Composite Steel Pipe: Carbon Steel Pipe lining Stainless Steel

Stainless steel pipe with thin-walled composite inner wall of carbon steel pipe, lined with stainless steel composite pipe‌ is a bimetal composite pipeline, mainly composed of carbon steel pipes as the base pipe, and the stainless steel liner pipe is combined with the base pipe through composite processes such as shrinkage, cold expansion, explosion or brazing.

This kind of pipe is composited with thin-walled stainless steel pipes on the inner wall of the steel pipe, which greatly improves the corrosion resistance of the steel pipes, while retaining the mechanical strength and good sealing of the steel pipes.‌.

Advantages

1. No staining, no nodules, corrosion resistance

Composite in steel pipe Thin-walled stainless steel pipe, because stainless steel contains18%-20% chromium, an extremely thin chromium oxide film is formed during use. This film prevents metal from continuing to oxidize, so stainless steel has strong corrosion resistance. It can not only withstand the corrosion of water and air, but also withstand the corrosion of weak acids and weak alkalis. The corrosion resistance and density of stainless steel are stronger than the galvanized layer of galvanized steel pipes. so,Lined stainless steel composite steel pipe During use, there is no need to worry about scaling or noduling caused by rust on the inner wall, which will cause the inner hole to shrink.

The corrosion resistance of stainless steel is much higher than that of carbon steel, and is lined with stainless steel pipes, which can be used to transport acidic or alkaline chemical fluids.

2. High strength, pressure resistance, stretch resistance

Lined stainless steel composite steel pipe The outer steel pipe in the middle is made of welded steel pipe, seamless steel pipe, and spiral seam welded pipe. The tensile strength of welded steel pipes or seamless steel pipes is greater than that of335MPa, elongation is greater than 15%, and the elongation of the steel pipe inline stainless steel composite steel pipe reaches more than 25%. The steel pipes have undergone water pressure tests of more than 3.0MPa and pass the standard specified Bending test,flattening test,Fracture toughness test, metallographic inspection, tensile test and higher strength pressure test. After the composite stainless steel pipes in the outer steel pipes increase the total wall thickness and strength, it can not only be used for civil water and gas transmission, but also for industrial fluids. When welded steel pipes are used in outer steel pipes, the strength reliability of composite steel pipes is improved because the welds of outer steel pipes and stainless steel pipes are not in the same position.

3. Can be soldered

Welding can be used. Before welding, mechanical methods and organic solvents should be used to remove at least each side of the weld surface and the welding bevel.Oil stains, rust, metal chips, oxide films and other dirt within 20mm. Welding equipment should meet the welding process requirements and comply with the relevant equipment standards. In the welding procedure, first weld the composite material (stainless steel pipe), then the transition layer, and finally the substrate (carbon steel pipe).

The surface of the composite weld should be kept as smooth and smooth as possible from the composite surface. When welding the transition layer, the amount of melting of the base metal should be minimized as much as possible while ensuring good fusion, that is, the melting and ratio should be reduced. Clean after welding, and carefully clean the welding slag, welding tumor splashes and other dirt on the surface of the weldment after welding. Welds should be partially trimmed if necessary. After cleaning after welding, welder marks should be stamped on obvious parts near the substrate weld for future inspection.

4. Can be connected to flange,CanThreaded connection

Lined stainless steel composite steel pipe The joint seal is a double-layer seal, the outer layer is a pipe thread seal, and the inner layer is a special structure silicone rubber seal ring seal, ensuring the reliability of the piping system seal. Can also be coated on the outside of the shoulder-type forged cast fittingsHA alloy coating has corrosion resistance performance that reaches the corrosion resistance of stainless steel.

5. YesTrench connection

Because of the large diameter of the pipe fittings of DN125-DN600, it is difficult to process threads and tighten threads, so the pipe fittings of DN125-DN600 should use grooved pipe joints and plastic lining blue. Trench pipe joints are carried out on the outer surface and end surfacesElectrostatic plastic sprayingTreatment, can also be plated outside the ductile iron grooved pipe jointHA alloy coating, the corrosion resistance level of the coating reaches the corrosion resistance level of stainless steel. Silicone rubber or food grade inside the connectorNitrile rubberThe sealing ring, fluid flows in the pipe and will not come into contact with the outer steel pipe.

exist Lined stainless steel composite steel pipe The outer surface of the end of the end is extruded out of the groove, and the two end sides of the grooved pipe joint are pressed into the groove. The grooved pipe joint consists of two flap grooved pipe joints, and the grooved pipe joints are connected by bolts and nuts. When the bolt and nut are tightened, the two grooved pipe joints are tightly clamped together to tighten the silicone rubber sealing ring in the grooved pipe joint. The silicone rubber sealing ring tightly hugs the ends of the two-section pipes together, and the fluid flows in the tube and the sealing ring, ensuring the sealing of the fluid flow.

In order to solve the corrosion problem of the end face of the pipe, an anti-corrosion sleeve is designed. The outer surface of the anti-corrosion sleeve and the inner surface of the inner surface of the stainless steel composite steel pipe lined is formed, so that the anti-corrosion sleeve on the end face of the stainless steel composite steel pipe lined is closely attached to the end face of the pipe lined with the stainless steel composite steel pipe. Sealant is applied between the anti-corrosion sleeve on the end face and the end face and the inner surface of the steel pipe. The sealant is a two-component. When used, the two components are mixed together to immediately generate a great adhesion force. The end-face anti-corrosion sleeve and sealant well solve the corrosion protection problem of the end-face of the pipe when using grooved connections.

6. Resistant to high temperatures, can transport hot water, boiling water, steam, low temperatures, good brittleness, small expansion coefficient

The thermal expansion and contraction of plastics exceeds that of steel10 times, and the extension capacity of plastic when it shrinks when it is cold, it is much lower than that of steel. Therefore, when the water in the pipe is frozen and expanded in cold seasons, the plastic pipe cannot shrink and recover after it is frozen and expands, and it expands multiple times, causing the plastic to expand beyond its limit and breaks brittle.Welded steel pipes Ensure elongation exceeds 15%,Stainless steel pipe The elongation ensures that it exceeds 25%, an outer steel pipe that can elongate and expand, and a stainless steel pipe with better elongation is lining to avoid brittle breakage when the water in the pipe is frozen and expands.

7. Good hygiene performance and can transport clean water

Since stainless steel pipes are not corroded by fluid during use, the stainless steel pipe body has no impurities entering the fluid, and the stainless steel composite steel pipe is lined with Stainless steel threaded pipe fittings,Stainless steel flange, stainless steel welded pipe fittings, the fluid does not come into contact with the outer steel pipe, and the fluid only comes into contact with the stainless steel, so the inner lined stainless steel composite steel pipe can replace pure stainless steel pipes to transport drinking water.

8. Low price

Steel pipes are covered with Thin-walled stainless steel pipe This reduces manufacturing costs and ensures thickness to ensure strength, so that the cost of installing inner lined stainless steel composite steel pipes is much lower than that of thick-walled pure stainless steel pipes and thick-walled pure copper pipes.

Production process

In the production of stainless steel composite pipes, the composite steel pipe manufacturer must be required to select different corrosion-resistant alloy layers as the inner lined pipes according to the requirements of the chemical company's process flow. Most corrosion-resistant alloys (such as pure titanium,Nickel-based alloy, ordinary stainless steel, duplex stainless steel) can all be used as inner lining layer. But for Duplex stainless steel In other words, the difficulty of recombination is very high because the yield strength of duplex steel is relatively large and the elongation of break is small. If the process control is not accurate enough, it is very easy to crack during the recombination process. Duplex stainless steel has two metallographic structures: austenite and ferrite, so it resists chloride ion corrosion andStress corrosion crackingGreat performance over316L. In salt making or salt chemical companies, duplex stainless steel composite steel pipes have very good performance advantages.

PCB Assembly SMT SMT process details

SMT (Surface Mounted Technology, Surface Mount Technology) is a pinless or short lead surface assembly components (SMC / SMD, that is, sheet components) directly mounted on the surface of the PCB (printed circuit board), and through the re-flow soldering or dip soldering and other methods to achieve the soldering and assembly of the circuit mounting technology. The following is a detailed introduction to the PCB assembly SMT SMD process:

First, the basic flow of the SMT placement process

Incoming material inspection

Inspection of the PCB board, to see if there is deformation, scratches, short circuit, open circuit and other issues, while checking the solder resist layer, silk screen layer and so on whether it meets the requirements.

The appearance, size, pin coplanarity of electronic components are tested to ensure that their quality is qualified. It is also necessary to sample test the electrical performance of the components to ensure that they meet the design requirements.

Solder Paste Printing

According to the design of the PCB board and the specifications of the components, a suitable solder paste stencil is selected and installed on the solder paste printing machine.

Using the solder paste printing machine, print the solder paste evenly on the pads of the PCB board. During the printing process, the thickness, shape and printing position of the solder paste should be accurately controlled to ensure that the solder paste can accurately cover the pads and there are no defects such as less solder, more solder, pulling tip and offset.

After printing, you can use SPI (Solder Paste Inspection) and other equipment to test the quality of solder paste printing.

Component placement

Mounter according to the pre-programmed program, from the material belt or tray to pick up the corresponding surface mount components, and will be accurately affixed to the PCB board on the designated location.

During the mounting process, attention should be paid to the polarity and direction of the components to ensure correct mounting. For some tiny components, such as 0201, 01005 and other packages of components, the mounter needs to have higher precision and stability to ensure the quality of placement.

Reflow soldering

The mounted PCB boards are sent into the reflow oven to be soldered under a certain temperature profile.

The reflow soldering process usually includes preheating, constant temperature, reflow and cooling stages. Preheating stage can make the solvent in the solder paste volatilization, to avoid air bubbles in the reflow process; reflow stage temperature to ensure that the solder paste is completely melted, the formation of a good welding connection; cooling stage to make the solder joints cooled quickly, curing the weld structure, improve the strength of the weld.

The temperature profile setting of reflow soldering should be optimized according to the component type and board material to avoid overheating or underheating resulting in weak soldering or component damage.

Quality Inspection

Visual inspection, automatic optical inspection (AOI), X-ray inspection, in-circuit tester (ICT), flying probe tester, function tester and other inspection means are used to comprehensively inspect the soldering quality and assembly quality of PCBA (printed circuit board assembly).

Visual inspection is mainly through manual observation of the PCBA surface to check whether there are components missing, offset, short circuit, false soldering and other obvious defects.

AOI, on the other hand, utilizes the principle of optical imaging to quickly scan the PCBA, detect welding defects, and automatically judge and mark them through image analysis software.

X-ray inspection is mainly used to detect soldering defects hidden inside components such as BGA (Ball Grid Array).

Rework and Depaneling

For the defective products detected, the use of soldering iron, rework workstations and other tools for rework processing, to remove the bad welding points, re-welding, to ensure that the product quality meets the requirements. Rework need to be tested again, until the product quality is qualified.

Separate multiple PCBs from the motherboard, usually using V-CUT or punching and cutting machines for board separation operations.

Grinding and washing

After the partition of the PCB need to grind and wash board processing to remove excess burrs and residues, to ensure that the board surface is clean and smooth.

Second, the characteristics and advantages of SMT placement process

High assembly density

SMT placement technology can achieve a higher assembly density, so that the PCB board can accommodate more functional modules, thereby realizing the miniaturization and multifunctionality of the product. For example, the smart phone motherboard densely arranged on a variety of chips and components, it is thanks to the SMT placement technology to achieve a powerful function in a limited space.

High production efficiency

SMT placement technology has a high degree of automation, can quickly and accurately complete a large number of components mounted, greatly shortening the production cycle of the product and reduce production costs.

High Reliability

SMT placement technology uses surface mount components, which have shorter pins, smaller size, lighter weight, and fewer soldering points, and therefore have higher reliability. In addition, SMT placement technology reduces electromagnetic and radio frequency interference and improves product stability.

Easy to realize automated production

SMT SMD technology can be combined with automated production equipment to achieve fully automated production line, improve production efficiency and product quality.

Third, the application areas of SMT placement process

SMT placement technology is widely used in various types of consumer electronics, communications equipment, industrial control, automotive electronics, aerospace and many other fields. With the continuous development and renewal of electronic products, SMT placement technology is also progressing and perfect, for the miniaturization of electronic products, multifunctionality, high reliability provides strong support.

Fourth, the development trend of SMT placement process

Miniaturization and high precision

With the continuous miniaturization of electronic products, SMT placement technology will also be towards the direction of miniaturization and high-precision development. Future SMT placement equipment will have higher placement accuracy and stability, and can handle smaller, more precise components.

Intelligent and automation

SMT placement technology will be combined with intelligent and automation technology to realize fully automated and intelligent production lines. Through the introduction of artificial intelligence, big data and other advanced technologies, production efficiency and product quality can be improved and production costs can be reduced.

Greening and environmental protection

With the increasing awareness of environmental protection, SMT placement technology will also develop in the direction of greening and environmental protection. Future SMT placement equipment will use more environmentally friendly materials and processes to reduce the impact on the environment.

In summary, the SMT placement process as the electronic assembly industry in the most widely adopted an advanced process, with high assembly density, high production efficiency, high reliability, easy to realize the advantages of automated production, etc., widely used in various types of electronic products. With the continuous progress and improvement of technology, SMT placement process will continue to play an important role in the future.

Q: How can no-clean fluxes improve the soldering process?

A: No-clean fluxes offer several advantages that can significantly improve the soldering process, particularly in modern electronics manufacturing. Here's how:

Eliminates the Need for Post-Solder Cleaning:

Traditional fluxes require cleaning to remove residues that might cause corrosion or affect insulation resistance. No-clean fluxes leave minimal, non-corrosive residues, eliminating the need for additional cleaning steps, reducing labor and costs.

Time and Cost Efficiency:

By removing the cleaning process, manufacturers save time, water, cleaning agents, and energy, streamlining the production process and improving overall efficiency.

Enhanced Reliability:

Residues from no-clean fluxes are designed to be inert and non-conductive, ensuring that they do not interfere with the performance of the soldered assembly, even in sensitive electronic applications.

Environmental Friendliness:

No-clean fluxes reduce the use of cleaning solvents, many of which are harmful to the environment. This aligns with sustainable manufacturing practices and regulatory compliance, such as RoHS and REACH.

Improved Solder Joint Quality:

Advanced no-clean flux formulations provide excellent wetting and flow, ensuring strong and reliable solder joints, even for challenging surfaces or components. For instance, the Electo 3127 series no-clean fluxes deliver exceptional soldering performance, leaving minimal residues while maintaining high reliability in demanding applications.

Versatility in Applications:Collapse

No-clean fluxes are suitable for a wide range of soldering processes, including wave soldering, reflow soldering, and hand soldering, making them adaptable across industries.

Key Considerations:

While no-clean fluxes, like the Electo 3127 series, are advantageous, their selection depends on the specific application and operating environment. Factors like thermal stability, residue profile, and flux activity should be evaluated to ensure optimal performance.

[melssblog]

Why is cleaning needed

Harmful contaminants such as solder and adhesive residues, flux, and dust and debris from other manufacturing processes and handling are often formed during the course of electronics manufacture, and the primary purpose of cleaning is to remove these contaminants at regular intervals. This ultimately leads to increased lifetime of the electronic product by ensuring good surface resistance and by preventing current leakage due to PCB failure.

With the constantly evolving cleaning market to meet the demands of the ever-expanding electronics industry, it is of paramount importance that the level of cleanliness required be clearly defined. A correct method must then be used to ensure that the level of cleanliness achieved meets the standard specified by the electronics engineer.

When to perform cleaning

There are many stages where cleaning is required:

Before stencilling and soldering to remove contaminants from the previous production stages

After stencilling to remove excess solder/adhesive

After soldering to remove corrosive flux residues and any excess solder

How is cleaning performed

Precise application of solder is often achieved using a stainless steel stencil over the printed circuit board. Once the circuit design has been finalised, it is mostly purchased as a set of a stencil and many PCBs (a single stencil can be used on thousands of PCBs). The solder is applied on the stencil through which it flows precisely onto the PCB below.

The ultimate goal of cleaning is to remove unwanted residue from the surface and under components. This is achieved by considering selection of components, board material compatibility, placement and defining solder mask in the Design Phase. The cleaning agent must be according to the solder alloy and flux composition with proper heat exposure. The Cleaning Agent must be selected with reuse, environmental, temperature, use rate and Health and Safety considerations in mind. Any Cleaning Machine used must perform proper fluid management, give a good throughput and consume less energy.

Types of cleaning in electronics manufacturing

Proper cleaning can be categorised into PCB Cleaning, Stencil Cleaning and Maintenance Cleaning.

PCB cleaning This can be further categorised into inline and batch aqueous sprays for in-air cleaning, ultrasonic and batch immersion cleaning, manual PCB and benchtop cleaning and vapour degreasing.

While inline washers use high flow, energy and deflective forces, batch cleaning machines are designed to wash, rinse and dry assemblies of smaller footprint. In ultrasonic and batch immersion cleaning, the product being washed is completely immersed in the cleaning agent using either ultrasonic energy or spray-under-immersion forces. Manual PCB and benchtop cleaning is required in rework and repairs to production assemblies and after hand placement of BGAs, connectors or other surface mount components and this is achieved by using an aerosol can or a pump dispenser and ensuring the right cleaning chemistry. In vapour degreasing, the engineered cleaning fluid is a blend of solvents which behave like an azeotrope to produce a constant boiling system at a specific temperature range.

Stencil cleaning

According to some estimates, up to 70% of solder defects are attributed to the stencil printing process. Stencil cleaning is categorised into under-stencil wiping to remove soils, ultrasonic cleaning to remove trace levels of solder paste from stencil openings, solvent-based cleaning to clean wet solder paste, adhesives and flux residues from stencils, mis-printed PCBs, wave soldering pallets, tools and fixtures, spray-in-air aqueous wash/rinse to rapidly dissolve the solder paste, hand-held stencil cleaning to remove trace levels of solder paste from the apertures, and misprint cleaning to address misprints due to issues such as clogged apertures, stencil out of alignment and solder paste rheology shifts.

How to choose the right types of masking tape?

Masking tape is an easily removed adhesive tape used temporarily covered or fixed. Masking tapes temporarily protect areas from painting, soldering, blasting, spraying, coating, plating, and polishing while these procedures are administered to nearby surfaces. The different types of masking tape use for different application.

Types of Masking Tape’s Carrier

A single-sided tape that it’s backing is self-wound around, without release paper liner. At present, there are mainly 6 different types of carrier on the market: Crepe paper masking tape, Washi paper masking tape, PE cloth masking tape, Cloth masking tape, PVC masking tape, PET masking tape.

Crepe paper or Washi paper is extra thin backing carrier.

It’s conformable ability to create crisp paint line and without paint bleeding past the edge. This type of masking tape is usually used as Painter’s Tape. It contains light and soft carrier and water based Acrylic adhesive. So painter’s tape mainly use to masking painting walls, automotive body.

PE cloth is PE laminated flat yarns weaved cloth carrier.

It is light and soft carrier but more stretch-resistant. The flat yarns cloth easy tear by hand with linear fracture. PE cloth masking tape coating water based Acrylic adhesive. It is fairly Anti-solvent and Anti-UV, waterproof. Most of applications are masking building steel structure, bridge steel structure, granite exterior wall, ceramic tile, concrete.

Cloth mean spun rayon cloth that similar to duct tape’s carrier.

It is thick cloth backing with heavy duty Rubber adhesive. So most of Cloth masking tape similar to duct tape but adhesive free-residue. It is good tack for irregular surface such as granite exterior wall, ceramic tile, concrete.

Sandblast tape also is a heavy duty Cloth masking tape with a tough resistant cloth backing and a strong adhesive.

This abrasive blasting tapes mask components during sandblasting, shotpeening, or other coarse-media finishing process. The thick rubber adhesive and backing provides wear resistance to covered areas.

PVC film is a vinyl carrier, the backing has good conformable ability, as well as more flexible workability.

PVC masking tape is also relatively cheap. Most of PVC masking tape use to masking the metal panels, Aluminum alloy door and window frames, glass.

PET film is a Polyester carrier have high resistance temperature and clarity characteristics.

PET masking tape usually used for holding tape. It is designed for the purpose of temporary fixation. So holding tape is often used to temporarily fix certain parts of electrical appliances or office equipment during transportation. Its ease of use and non-residue characteristic makes it an excellent functional tape.

Types of Masking Tape’s Adhesive

Since masking tape’s intent is temporary, the removal needs to be residue-free. This limits the adhesive options for different types of masking tape. Most types of Masking tape for painting applications use water based Acrylic adhesive. Such as Painter’s tape and PE cloth tape, their adhesive layer is very thin and transparent. Acrylic-based adhesives create the good conformable and no bleed performance of Masking tape. It can reach their maximum adhesion almost immediately upon application, have adequate resistance, require no preparation, and have good sheer and peel strength Natural rubber adhesive mainly use to irregular surface masking. It’s thick adhesive layer have good tack. Such as cloth masking tape and Sandblast tape. Silicone adhesive have a high degree of flexibility and very high temperature resistance (600°F). It available as a heat masking application, or low temperature resistant, the masking tape will be wide application.

Electrolyte Anti-penetration Absorption Material, SINOYQX Melamine Foam

What is electrolyte?

Electrolyte is the medium used in chemical batteries, electrolytic capacitors, etc., and its representative content varies greatly in different industries. There are electrolytes in living organisms (also called electrolytes), there are also electrolytes used in the battery industry, as well as electrolytes in electrolytic capacitors, supercapacitors, and other industries.

The compositions of electrolytes used in different industries vary greatly, or are even completely different. For example, the human body's electrolytes are mainly composed of water, sodium chloride, pH buffering substances, etc.; the electrolyte of aluminum electrolyte capacitors contains major solvents such as GBL; the supercapacitor electrolyte contains propylene carbonate or acetonitrile as the main solvent; the electrolyte of lithium manganese primary battery contains main solvents such as propylene carbonate and ethylene glycol dimethyl ether;  lithium-ion battery electrolyte contains main solvents such as ethylene carbonate, dimethyl carbonate, ethyl methyl carbonate and diethyl carbonate. Their respective conductive salts are also completely different, such as sodium chloride in the human body, tetraethylammonium tetrafluoroborate in the supercapacitor electrolyte, and lithium perchlorate or lithium triflate commonly used in lithium manganese primary batteries. And in lithium-ion batteries, it is lithium hexafluorophosphate.

There are many advantages to using electrolyte as a cathode. The first is that the contact area between the liquid and the medium is large, which is helpful to increase the capacitance. Secondly, electrolytic capacitors made with electrolyte can withstand high temperatures, so they can pass wave soldering (wave soldering is an important process for SMT patch installation), and they also have relatively strong voltage resistance. However, the electrolyte also has shortcomings, and there are potential safety hazards, such as environmental pollution, fire, and human injury caused by leakage.

What are the dangers of electrolyte leakage?

1. Inhalation hazards

Fine gas suspensions in the electrolyte are easily mixed into the atmosphere. Especially when the temperature rises, the poisonous gas in the electrolyte is easily inhaled, which can cause neurotoxicity in the human body. Lithium battery electrolyte can cause respiratory, eye, and skin irritation, with symptoms including cough, diarrhea, headache, blindness, and skin burning.

2. Skin contact hazards

When a large amount of gas is released, the electrolyte is easy to splash out and meet the skin, which can cause skin burns, irritation, and allergic skin diseases. It can even cause severe tissue fragmentation and coagulation, skin whitening, blisters, irritating eczema and ulcerated dermatitis symptoms.

3. Risk of eye contact

The electrolyte can not only pass through the skin, but also stick along the facial skin and into the eyes. If not treated in time, it can cause further damage to the retina and eye membranes, and cause symptoms such as pain, irritation, eye warmth, tearing, eye itching, and itching.

4. Dangers of dietary intake

When improperly maintained, the electrolyte of the electrolyte splashes into food, which can cause harmful substances such as ions, acids, alkali impurities, and heavy metals in the liquid to contaminate food and water sources. These substances have an extremely serious impact on human health and can cause symptoms such as nausea, vomiting, general discomfort, stomach pain, gastrointestinal soreness, and even death.

5. Flammability hazards

If there is contamination or large amounts of leakage, flammable gases can easily form. Once a fire occurs, the lithium battery electrolyte flame will become violent and the fire will accelerate significantly, increasing the disaster.

6. Environmental pollution hazards

The discharge of electrolyte not only damages the environment, but also affects the fertility of the soil. And it cannot be decomposed, even if it is affected by natural degradation in the atmosphere and water, it will remain in the surface soil and water. Long-term contamination of land and water sources may also pose potential threats to human health.

How to prevent electrolyte leakage?

The use of anti-penetration absorbent materials can effectively prevent electrolyte leakage. Melamine foam, for example, can be used to absorb leaked electrolyte after the adapter's electrolytic capacitor fails to avoid safety issues such as power short circuit caused by electrolyte.

Magnet wires can be classified according to their basic composition

Sometimes it is also classified according to the particularity of its use, such as self-adhesive enameled wire, refrigerant-resistant enameled wire, etc. Due to the large insulation thickness and low High quality China Polyurethane Enameled Copper Wire heat resistance, most of them have been replaced by enameled wires. Later, polyvinyl formal enameled wire came out, and its mechanical properties were greatly improved. Magnet wires can be classified according to their basic composition, conductive core and electrical insulation layer.

In the early days, cotton yarn and silk, called yarn covered wire and silk covered wire, were used in motors and electrical appliances. The paint film can fall off by itself in the high-temperature tin enamel tank, making the copper wire easy to solder. But its mechanical strength is poor, and it can only be used in micro motors and small motors. It can be directly used in motor windings and is called high-strength enameled wire. In recent years, the rapid development is the film wrapping wire, mainly polyester film and polyimide film wrapping wire. Enameled wire can be divided into polyester enameled wire, polyesterimide enameled wire, polyamideimide enameled wire, polyimide enameled wire, polyesterimide/polyamideimide enameled wire, corona resistant enameled wire, and oily enameled wire according to the insulating varnish used.; the latter includes the requirements of stretching, bending and abrasion during winding and embedding, as well as swelling and erosion during dipping and drying.

The former includes its shape, specifications, ability to work at high temperatures for short and long periods of time, as well as withstanding strong vibration and centrifugal force at high speeds in some occasions, resistance to corona and breakdown under high voltage, and resistance to chemicals in special atmospheres Corrosion, etc. With the development of weak current technology, there has been a self-adhesive enameled wire, which can obtain a coil with better integrity without dipping and baking. Paper-covered wire still occupies a considerable position in the wrapped wire, which is mainly used in oil-immersed transformers. It needs to be covered with cotton yarn when used. As the application of enameled wire is becoming more and more extensive, the requirements are becoming stricter, and composite enameled wire has been developed. The existing inorganic insulated wires can be further divided into glass film wires, oxide film wires and ceramic wires. Generally, it is divided into enameled wire, winding wire, enameled winding wire and inorganic insulated wire according to the insulating material and manufacturing method used in the electrical insulation layer.

There are also combined wires, transposed wires and so on.What is enameled wire? Enameled wire, a type of magnet wire, generally refers to insulated wires used to make coils or windings in electrical products. The paint film has poor abrasion resistance and cannot be directly used to make motor coils and windings. The oil-paper insulation formed at this time has excellent dielectric properties, is low in price, and has a long life. The enameled wire is coated with a corresponding lacquer solution on the outside of the conductor, and then it is made by solvent volatilization and solidification of the lacquer film and cooling. Also called winding wire. Magnet wires must meet the requirements of a variety of uses and manufacturing processes. Inorganic insulated wire When the heat resistance rating exceeds the limit of organic materials, inorganic insulating varnish is usually used. In addition, in order to avoid the trouble of first removing the paint film during soldering, direct soldering enameled wire has been developed. Currently it is only used as a high-frequency winding wire.

Recently, there is also a mica tape-coated polyesterimide film-coated rectangular copper wire used for wind power generation. The earliest enameled wire was oily enameled wire, made of tung oil. The inner and outer paint films are composed of different polymer materials, such as polyesterimide/polyamideimide enameled wire. In the large and medium-sized winding wires, when the heat resistance grade is higher and the mechanical strength is higher, the glass fiber covered wire is also used, and the appropriate adhesive paint is used in the manufacture. Paint, acetal paint, polyurethane enameled wire, etc. Wrapped wire An important variety in winding wire

Are you ready to conformal coat? Here’s why you might want to know.

Over the holidays, I had occasion to watch a National Geographic documentary on the April 2019 fire that took place in the Notre Dame cathedral in Paris. A segment of the show touched on how the city fire department utilized an unmanned, 1,110 lb. fire-fighting machine, lovingly called the Colossus, to enter parts of the inferno unsafe for human firefighters. Not only was this advanced unit charged with discharging 660 gallons of water per minute into the blaze and providing a live video feed and sensor data to provide valuable insights on the fire’s progress to nearby fire chiefs - it had to perform these and other duties under the duress of incredible heat, drenched in water, and withstanding various impacts and vibration from falling or fallen debris, including molten lead from the cathedral’s lead roof. Talk about hostile workplaces!* * You can read more about and see the Colossus in action, here. Needless to say, the story brought to mind the advances the electronics industry has made and continues to make in the arenas of mobility, connectivity, processing, and - especially in this instance - durability. After all, machines like this don’t just happen: From major systems, to sub-assemblies, to individual components, on down the line — they are painstakingly designed, spec’d, and built to perform in adverse conditions. Which brought to mind the increased importance of the protection afforded by conformal coatings. What is conformal coating? Conformal coating involves spraying or immersing a printed circuit board (PCB) or PCB assembly in a protective coating - in much the same way that a car manufacture or service shop applies a coating undercarriage of your car. The applied material ‘conforms’ to the irregular surface or landscape of a PCBA, including surface-mounted components, solder points, raised or etched circuits, component leads, through-holes, and more. Once applied, applied conformal coatings must dry or cure for a suitable period of time before additional processing, assembly, quality control, or other tasks can proceed. Once applied, such coatings can protect against any number of strains your circuit may encounter in the real world, including: -Moisture, oils, chemicals, solvents -Thermal stresses, including extreme heat and cold Vibration, abrasion, physical impacts, handling during shipping, regular use, or service -Dust, dirt, grime -Ultraviolet (UV) exposure and degradation -Unexpected electric shocks (transient voltage surges, aka: lightening), shorts, and static electricity -Radiation What are conformal coatings made of? Conformal coatings or ‘resins’ come in a variety of compositions to match your unique application or performance goals. While other materials are available, including a new breed of ‘nano’ coatings, the three major types of traditional coating material options are: -Apoxy Resin (AR) is a rigid coating that offers basic, low-cost dust and moisture protection. Apoxies are, though, susceptible to chemical solvents, which makes it easier to intentionally remove the coating to do rework and field repairs easier, even if it also makes them less-than-ideal for caustic industrial settings. -Silicone Resin (SR) is a flexible, hydro-repellent material suitable for high-vibration and/or outdoor environments. SR-based coatings also have excellent dielectric properties, so they can help isolate high-voltage (aka: eliminate arcing) or, inversely, help protect static-sensitive components or PCBAs. -Urethane Resin (UR) is a hard coating that offers even better moisture and chemical resistance than SR- and AR-comprised coatings, which makes them a frequent choice in mission-critical aerospace, defense, avionics, or medical applications. Key considerations of conformal coating For a material that measures only 1-5 microns in thickness - the particulars of conformal coating composition, characteristics, and application require a deeper discussion than this blog post allows. That said, I can say choosing the right conformal coating for your unique application can be guided by five high-level considerations: -What kind of protection do you require? As outlined above, different conformal coatings offer different levels of protection. To pick the right one for your project, list and rank your priorities - permeability to moisture, chemical resistance, dielectric performance, ability to withstand or adjust to thermal contractions/expansions, vibration, and so on - and then work with your PCBA supplier to choose the right one for your job. -What sort of production process or timing are you working with? Are you working with small volumes where application of the coating can be manual, or high-volume runs that demand automation? Can your production schedule withstand long or short conformal coating curing times? What sort of quality system regimen do you or your customer demand to ensure repeatability? These and other production and process aspects should be accounted for when choosing your conformal coating. Speaking of QA, will your PCB, assembly, or finished device have compliance requirements? Individual customers may have proprietary specs or requirements, but most applications for conformal coated PCBs and PCBAs are commonly assessed against two prominent, namely IPC-CC-830B (or MIL-I-46058C) and UL746E. -Will the end device or equipment require rework or even allow for in-the-field repairs? If so, some coatings are better suited than others. -What’s the budget? No surprise that a hard-nosed cost/benefit analysis will be needed in choosing your conformal coatings, just as it does with every other item on your BOM. Thankfully, the wide range of conformal resins, application techniques, and suppliers - and availability of emerging coating options - all but ensure there is an option to suit your task without too many trade-offs. Which applications require conformal coating? The length of this blog here again precludes an exhaustive analysis of environments and applications that would benefit from resin-coated electronics. Still, my opening story of the Colossus fire-fighting machine makes clear some emerging applications are particularly well-suited to ruggedized electronics enabled by conformal coated circuits. For instance: -Unmanned vehicles - Robots with fire-fighting capabilities are just the beginning of this fast-growing field. (Come to think of it, I wonder if any were or could have been used to save lives and property during the Oregon wildfires that plagued CST’s own region last July?) Similar equipment is being applied in mines, sites of industrial accidents, war zones and law enforcement applications, and deep-sea, arctic, and space exploration, among other extreme environments. -Internet of Things (IoT) - Enabled by nearly ubiquitous broadband access (including 5G), connected sensor networks, and insatiable demand for/insights from big data and machine learning are also driving electronic devices into harsh and remote environments: Think of far-flung water, gas, and oil pumps; all-season sensors deployed across forests, farm fields, and water systems; traffic, vibration, and erosion sensors dispersed across interstate highways, bridges, rail systems, and cityscapes. -Communications infrastructure - Having mentioned how communications networks are drawing IoT technology into challenging environments, the same can be said for the infrastructure comprising those networks themselves. Base stations, cell towers, satellite dishes, antennae, mobile wireless equipment, and even satellites are subjected to a wide range of environmental stresses, making them key candidates for conformal coatings among other protective measures. -Handheld technology - Aided by miniaturization, innovative packaging solutions, and IoT connectivity mentioned above, handheld devices and other types of portable equipment are also driving technology into environments requiring ruggedization techniques like conformal coating. Two examples of this trend would be mobilized medicine and laboratories that bring healthcare and science into ever more remote challenging geographies — and app-driven handheld tools that enable industrial technicians to perform in-the-field maintenance, diagnostics, and even repairs. Need conformal coating? CST is here to help. In addition to assisting you with design and manufacture of your PCBA, Cascade Systems Technology has the experience, expertise, and infrastructure to help you choose, engineer, and apply the optimal conformal coating for your unique application. From small runs dictated by complexity or by production-on-demand schedules - to continuous, high-volume runs requiring high levels of automation - CST has your PCBA and conformal coating needs covered!
