Blood Glucose Meters – Precision in Diabetes Management

Blood glucose meters are essential devices for individuals with diabetes, enabling them to monitor their blood sugar levels regularly. These devices provide critical feedback, allowing users to adjust their insulin intake, diet, or physical activity levels. The key to effective diabetes management lies in the accuracy of these devices, and this accuracy is largely determined by the quality of the printed circuit board (PCB) used in the device. In this article, we will explore how blood glucose meters work, the components involved, and the role of PCBs in ensuring the device operates reliably.

How Blood Glucose Meters Work Blood glucose meters work by measuring the concentration of glucose in a small sample of blood. The user pricks their finger with a lancet, places a drop of blood on a test strip, and inserts it into the meter. The test strip contains chemicals that react with glucose in the blood, producing a small electrical current. This current is measured by the meter’s PCB, which processes the signal and displays the blood glucose level on the screen.

The Components of a Blood Glucose Meter A typical blood glucose meter consists of several key components: the test strip, the sensor, the microprocessor, the display, and the battery. The test strip reacts with the blood, producing a small electrical signal. The sensor detects this signal and sends it to the microprocessor, which processes the data and calculates the glucose level. The display unit shows the result, while the battery ensures the device is powered.

PCBs in Blood Glucose Meters The PCB in a blood glucose meter is responsible for connecting and controlling the various components, including the sensor, microprocessor, and display. It ensures that the electrical signals generated by the test strip are accurately processed, providing a reliable reading of the glucose concentration. The PCB also helps manage power consumption, ensuring that the device remains efficient and ready for use when needed.

Why High-Quality PCBs Matter in Blood Glucose Meters Accuracy is essential in blood glucose meters, as inaccurate readings could lead to dangerous health consequences. A poorly designed PCB can result in faulty readings, miscalculations, or device malfunction. Therefore, the quality of the PCB is paramount in ensuring that these devices deliver precise and consistent results. High-quality PCBs also contribute to the overall reliability and longevity of the device.

What are Rigid-Flex Circuit Boards?

As the name implies, a Rigid-Flex PCB is a hybrid of a Flex PCB and a Rigid PCB. The combination of the two types of boards utilises the benefits each one provides, integrating the versatility of the flexible board with the robustness of the rigid board. Rigid-flex printed circuit boards are used in more complex mechanical designs, eliminating flexible cables and wiring and replacing it with integrated circuits.

Rigid-Flex PCBs, by definition, are a combination of rigid part(s) joined by interconnecting flex areas where the flex material is used across the entire PCB area.

The rigid parts are where there is no bending requirement. Again, PTHs take connections from layer to layer as required. Rigid-flex may also employ other technologies as required eg. HDI. Unlike the cost-effective flex PCBs, Rigid-Flex PCBs can be a bit more costly due to their intricate design.

Rigid-flex PCB design can be used to eliminate or greatly reduce requirements for bulky and costly cable harnesses, in turn taking out costs and reducing assembly time. Like the pure flexible PCBs, a high volume of rigid-flex PCBs are used in aviation and space applications – and also in automotive and test equipment.

The flexible layers of a Rigid-Flex PCB are buried within the board and penetrate through the rigid sections of the PCB.

The trend to miniaturization in electronics continues. Integrated circuit board solutions are becoming more and more popular as a means of efficiently utilizing the even smaller casing volume in all three dimensions.

A rigid-flex printed circuit board is unique as the rigid part of the circuitry can be placed directly into the application. Then, the flexible section can be bent and even folded to fit around components to make another direct connection. This aspect ensures a reliable connection to parts for higher performance.

Some of the most common products that incorporate rigid-flex PCBs in their design include laptop computers, smartphones, and wearable devices due to the bending capabilities of rigid-flex.

Rigid-flex pcb boards are PCBs that have Flexible PCBs (FPC) and Rigid PCBs on the same board, which are commonly employed to save space, remove wiring assemblies and can also be welded with complex components. Combining other higher technology boards, such as HDI, as a part of its packaging, is also a common design.

Rigid Flex PCB design

The designs of Rigid Flex PCBs are a little more complex as these boards are designed in 3D, which allows the board to be folded or twisted to create the desired shape for the product. Designing a board in 3D means they can offer greater spatial efficiency and can subsequently be used in special instances where space and weight reduction may be necessary, such as in medical devices. By being able to design in three dimensions designers can twist, fold and roll the flexible board substrates to achieve their desired shape for the final application's package.

Rigid Flex PCBs are usually thinner than other boards, meaning it’s a great option for any thin or light packaging needs your products may have. With thin copper layers and adhesive-less laminates, it’s a great small, thin and light solution for your circuit design needs.

Rigid-Flex PCBs Fabrication Applications:

Rigid-Flex PCBs offer a wide array of applications, ranging from smart devices to cell phones and digital cameras. Increasingly, rigid-flex board fabrication has been used in medical devices such as pacemakers for their space and weight reduction capabilities. The same advantages for rigid-flex PCB usage can be applied to smart control systems.

In consumer products, rigid-flex doesn't just maximize space and weight but greatly improves reliability, eliminating many needs for solder joints and delicate, fragile wiring that are prone to connection issues. These are just some examples, but Rigid-Flex PCBs can be used to benefit nearly all advanced electrical applications including testing equipment, tools and automobiles.

Rigid-Flex PCB and Its Production Process

The development of FPC and PCB has spawned a new product that is called rigid-flex PCB. Therefore, rigid- flex PCB is according to the relevant process requirements and through the lamination process to combine rigid board and flex board to form a circuit board with FPC characteristics and PCB characteristics.

Because rigid-flex PCB has a variety of complex structural forms, the manufacturing process is also different. Below picture shows the regular rigid-flex PCB and an example for regular stack up design.

Rigid flex PCB production is based on below steps: the first step is to process the rigid outer cover layer. The electroplating graphic that needs to be pressed in the outer layer, and then through the CNC milling machine, punching or laser method, routing out or routing the half of depth of the flexible part which is located in rigid layer. Flex board and the rigid outer cover are boned by adhesive sheet. The adhesive sheet has been pre-opened in the flexible part.

During the lamination process, if the rigid outer layer uses routing structure, a suitable pressure filling board should be prepared for the flex part. Using a vacuum pressing machine to obtain better press quality, and meanwhile with some auxiliary coating materials, such as PE, etc., so that the pressing process can provide a uniform pressure on the entire board, and make the low -flowing sticky sheet is fully flowing and filling the gap, especially for complex structures. Before adhesion or lamination, appropriate baking should be done as needed to remove moisture.

After lamination, the rigid- flex PCB can use a through hole treatment process which is similar to a multi-layer rigid board, the different part is remove drilling dirt. The method of removing drilling dirt depends on what materials used. Like the rigid board, drilling the hole after fully baking, and then use the plasma etching process to remove the residue in the hole wall. Before the plasma is treated, bake is also needed to remove water vapor. Caval polyesterness is generally recommended to not exceed 13um. The pore -plating process of conventional rigid board can be used, but the specific process parameters of the electroplating should be determined according to the reliability test data of the pores.

The next process is similar to the multi -layer rigid board. The outer layer etching, covering membrane (welded film), surface treatment, etc. can be used in similar processes. When making outline of the rigid-flex PCB, remove the filling board in the flexible part or depth control rigid outer cover in the flexible area can be formed into a rigid-flex PCB.

Careful consideration of Rigid-Flex solutions and a proper assessment of the available options at the early stages in the rigid-flex PCB design phase will return significant benefits. The Rigid-Flex PCBs fabricator must be involved early in the design process to ensure the design and fab portions are both in coordination and to account for final product variations.

The Rigid-Flex manufacturing phase is also more complex and time-consuming than rigid board fabrication. All the flexible components of the Rigid-Flex assembly have completely different handling, etching, and soldering processes than rigid FR4 boards.

Benefits of Rigid Flex PCB

Space requirements can be minimized by applying 3D

By removing the need for connectors and cables between the individual rigid parts the board size and overall system weight can be reduced.

By maximizing space, there is often a lower count in parts.

Less solder joints assure higher connection reliability.

Handling during assembly is easier in comparison with flexible boards.

Simplified PCB assembly processes.

Integrated ZIF contacts provide simple modular interfaces to the system environment.

Test conditions are simplified. A complete test prior to installation becomes possible.

Logistical and assembly costs are significantly reduced with flex-rigid boards.

It is possible to increase the complexity of mechanical designs, which also improves the degree of freedom for optimized housing solutions.

Rigid Flex PCB Fabrication Applications

Rigid flexible PCBs offer a wide array of applications, ranging from cell phones to digital cameras. Increasingly, rigid flex board fabrication has been used in medical devices such as pacemakers for their space and weight reduction capabilities. The same advantages for rigid flex PCB usage can be applied to control systems

In consumer products, rigid flex doesn't just maximize space and weight but greatly improves reliability, eliminating many needs for solder joints and delicate, fragile wiring that are prone to connection issues. These are just some examples, but rigid flex PCBs can be used to benefit nearly all advanced electrical applications including testing equipment, tools and automobiles.

Available structures for rigid flex PCB

There are numerous, different structures available. The more common ones are defined below:

Traditional rigid flex construction (IPC-6013 type 4) Multilayer rigid and flexible circuit combination containing three or more layers with plated through holes.

Asymmetrical rigid flex construction, where the FPC is situated on the outer layer of the rigid construction. Containing three or more layers with plated through holes.

Multilayer rigid flex construction with buried / blind via (microvia) as part of the rigid construction. 2 layers of microvia are achievable. Construction may also include two rigid structures as part of a homogeneous build.

Rigid Flex Printed Circuit Board Manufacturer

Rigid flex printed circuit boards (PCBs) are manufactured by combining rigid and flexible board technologies. These circuit boards are made up of multiple flexible circuit inner layers. An epoxy pre-preg bonding film is used to attach together these inner layers. The key benefit of these boards is that they are a combination of the best quality of flexible and rigid circuit boards. This can have several further benefits as far as stability, assembly, signal transmission, and overall size of the circuit are concerned. Hitechpcb provides a number of variants in rigid flex PCBs, which include 4 layer rigid flex with ENIG finish, 10 layer rigid flex with 4 layer flex, 12 layer rigid flex with heat sink, 14 layer rigid flex circuit boards, and many more. It is one of the leading rigid flex PCB manufacturers.

Every printed circuit board depends on the copper for carrying electricity. We understand that copper thickness plays a key role in the performance of these circuit boards. Thus, we allow the customers to choose from a variety of copper thicknesses, including 0.5 OZ, 1.0 OZ, 2.0 OZ, 3.0 OZ, up to 6 OZ. The solder mask helps in improving the aesthetic appeal of the components on the PCB. We can provide rigid flex printed circuit boards in various solder mask colors, including white, black, blue, green, red, and Taiyo PSR4000 white. The PCB can be availed in silkscreen colors – black and white.

Rigid flex printed circuit boards have minimal space requirements that are optimized by 3D application. These circuit boards require no cables or connectors between the rigid parts. This helps reduce the board size, as well as overall system weight. These lesser solder joints also help assure high connectivity. Additionally, these boards have ZIF contacts that are integrated. These contacts help simplify the system interfacing. This 4 layer rigid flex PCB and other printed circuit boards are vacuum packed during the transit. This helps us assure the quality, as well as working condition of the boards.

The Disadvantage and Advantage of Rigid-Flex PCB

Rigid-flex PCB has many production processes with the characteristic of superior difficulty in production and high defect rate. Its biggest disadvantage is that the price is more expensive than flex PCB or rigid PCB and long production cycle. Another disadvantage is that both SMT and furnaces may need to use carrier to support the flex PCB which virtually increases the SMT cost.

One of the key features of rigid-flex PCB is the thin profile and changeable shape, making it an ideal solution for ultra -thin and ultra -light packaging. Although the rigid flex PCB may be more expensive in design and manufacturing, they do have many advantages and can solve many problems in traditional hardboard technology.

1. Small Size and Flexible Shape

The rigid- flex PCB is easier to install more components in smaller space, because they can change the shape according to a specific contour. This technology will reduce the size and weight of the final product and the overall system cost. At the same time, the compact shape of rigid flex PCB makes it the best choice for fine lines and high -density circuits in HDI technology.

2. Customized for Different Applications

Rigid-flex PCB has various packages, which can be customized for the application of many industries such as medical equipment and consumer electronics. They can customize the size and shape to adapt to the shell design and 3D design, which provides designers with more possibilities to meet different requirements in specific applications.

3. Better Mechanical Stability

The stability of the rigid board and the flexibility of the flexible board form the stable structure of the entire packaging, while retaining the reliability and flexibility required for small space installation.

4. Good Performance in Harsh Environments

Rigid-flex PCB has high resistance and high vibration capacity, so they can work normally in a high -stress environment. There are fewer cables and connectors used in rigid-flexible PCB, which also reduces security risks and maintenance in future use.

5. Easy to Manufacture and Test

The rigid-flex PCB requires a small number of inter connect and related components/parts. It helps simplify the assembly operation, making rigid –flex PCB easier to assemble and test. Rigid-flex PCB is very suitable for PCB prototypes.

In addition to the above advantages, other common advantages of rigid-flex PCB also include high circuit density, good heat dissipation and good chemical resistance. In a word, rigid-flex PCB combines all the advantages of rigid PCB and flex PCB, and at the same time make up for the shortcomings. This PCB is the best solution to design reliable and powerful circuits for smart wearable devices and other industries.

Package Substrate: The package substrate serves as the foundation for the entire FCBGA package. It is typically made of materials like ceramics or glass fiber-reinforced epoxy resin (FR4). This layer provides structural support and ensures good connectivity between the solder balls and external circuit boards.

Heat Dissipation Layer: For high-power chips, heat management is crucial. FCBGA substrates often incorporate heat dissipation layers made of copper or other high thermal conductivity materials. These layers help transfer heat from the chip to the external environment, preventing overheating and chip damage.

Testing and Encapsulation Layer: During the manufacturing process, the FCBGA package undergoes extensive testing to ensure each package works as expected. The encapsulation layer is usually made of polymer materials and serves to protect the chip while adding mechanical strength to the package.

Advantages of FCBGA Substrate

FCBGA substrates offer many advantages due to their unique design and material choices. These benefits are especially apparent in high-performance and high-density electronic devices. Here are some of the key advantages:

High-Density Interconnects (HDI): The flip-chip design and ball grid array layout support extremely high interconnect densities. The circuit lines on the substrate can be packed more tightly, reducing the package size while enhancing electrical performance.

Excellent Thermal Management: FCBGA substrates excel in thermal management, effectively transferring heat from the chip. Since high-power chips generate a lot of heat, effective thermal design is essential to ensure reliable chip performance and longevity.

Smaller Package Size: FCBGA packages are typically smaller than traditional packages, making them ideal for applications where space is limited. This compact design allows for the integration of more functions into devices like high-end smartphones, servers, and portable electronics without increasing their size.

High-Speed Signal Transmission: The flip-chip design reduces the signal transmission path length, allowing for faster data transfer speeds. This feature is crucial for applications that require high-speed computation, such as processors and graphics chips.

Improved Reliability: The solder ball connection method used in FCBGA packages is more reliable than traditional pin-based connections. It can withstand higher mechanical stresses and temperature fluctuations, making it ideal for high-reliability applications.

Applications of FCBGA Substrate

FCBGA substrates are used across a wide range of electronic products, particularly in industries where high performance, high density, and high reliability are required. Some of the key applications include:

Central Processing Units (CPUs) and Graphics Processing Units (GPUs): FCBGA packaging is commonly used for high-performance computing chips like CPUs and GPUs, which require high processing power and effective heat management. The FCBGA substrate provides the necessary high-density connections and thermal dissipation needed for these chips to run efficiently at higher speeds and lower temperatures.

Servers and Data Centers: Processors used in servers and data centers need to handle large amounts of data, making their packaging requirements extremely demanding. FCBGA substrates' high-density interconnects and excellent thermal performance make them ideal for data center processors.

Mobile Devices: Processors and graphics chips in smartphones, tablets, and other mobile devices also utilize FCBGA packaging. The compact nature and efficient thermal management of FCBGA substrates are particularly suited for mobile devices that face size constraints.

Automotive Electronics: FCBGA substrates are also used in automotive electronics, such as self-driving, in-car entertainment systems, and electric vehicle control units. Automotive electronics must perform reliably in harsh environments, making the high durability and thermal management capabilities of FCBGA packaging a perfect fit.

Challenges and Future of FCBGA

While FCBGA substrates offer significant advantages, they also face some challenges:

Manufacturing Cost: The manufacturing process for FCBGA substrates is complex, involving precise fabrication and material selection, which increases the cost compared to traditional packaging methods. This could limit its use in lower-end products.

Thermal Issues: Although FCBGA substrates have good thermal management, as chip power increases, managing heat dissipation remains a challenge. Finding the balance between high-power density and effective cooling continues to be a key focus of packaging research.

Signal Integrity: High-speed signal transmission presents a challenge for FCBGA packaging. As chip frequencies increase, ensuring signal integrity and minimizing signal interference become critical issues in the design process.

FCBGA substrates are a crucial component in modern electronic packaging, offering high density, performance, and reliability. They are widely used in processors, GPUs, servers, mobile devices, and automotive electronics.

Flexible PCB Manufacturing

[email protected]

What is Flex PCB?

Flexible printed circuits, also known as flex circuits, are sometimes regarded as a printed circuit board (PCB) that can bend, when in reality there are significant differences between PCB’s and flex circuits when it comes to design, fabrication and functionality. One common mistake that designers make is to design a flexible circuit using the same rules as a PCB. Flex PCB require a unique set-up and have their own set of design rules that the Hitechpcb team has termed “flex-izing” and have worked hard to perfect over the last many years.

Flexible PCB, which also called Flex PCB, Flexible circuit board or flex circuit, it consists of PI base material, adhesive layer, copper layer, coverlay and sometimes with stiffeners. Flexible PCBs are now being used widely to replace traditional FR4 PCB in various different applications due to the benefits from flex PCB specially. Although more expensive than a normal rigid PCB, the right design in the right application could save weight and time in assembly, coupled with the reliability which makes flexible circuit board a worthwhile consideration.

A flexible printed circuit consists of a metallic layer of traces, usually copper, bonded to a dielectric layer, usually polyimide. Thickness of the metal layer can be very thin (<.0001″) to very thick (> .010″) and the dielectric thickness can vary from .0005″ to .010″. Often an adhesive is used to bond the metal to the substrate, but other types of bonding such as vapor deposition can be used to attach the metal.

How to calculate your flex pcb bend radius?

Because copper tends to readily oxidize, the exposed surfaces are often covered with a protective layer, gold or solder are the two most common materials because of their conductivity and environmental durability. For non-contact areas a dielectric material is used to protect the circuitry from oxidation or electrical shorting.

The number of material combinations that could go into a flexible printed circuit are nearly endless; current, capacitance, chemical and mechanical resistance, temperature extremes and type of flexing are just some of the criteria that impacts the material selections that best meet the functional needs. An experienced Hitechpcb design engineer takes the critical requirements into consideration when designing a circuit to meet your needs.

Flexible printed circuit boards (FPC) has become a common component of electronic products due to its lightness and flexibility performance. It is widely used in smart terminal, wearable electronics, consumer, automotive, industrial and medical fields. The miniaturization and integrated function of electronics product development is driving FPC to fine line and multilayer design.

What is Multilayer flex PCB?

This type of flexible printed wiring boards are multilayered (with three or more conductor layers) and require plated-through holes. We could use through vias, buried vias and blind vias.

A multi layer flex circuit combine several single-sided or double-sided circuits with complex interconnections, shielding and/or surface mounted technologies in a multi layer design. The multi layers may or may not be continuously laminated together throughout the production process. If your design needs require maximum flexibility, continuous lamination may not be appropriate. Multi layer circuits are an effective solution when confronted with design challenges such as: unavoidable crossovers, specific impedance requirements, elimination of crosstalk, additional shielding and high component density.

Decreased Assembly Time and Costs

Design Freedom

Flexibility during Installation

High Density Applications

Improved Airflow

Increased Heat Dissipation

Increased System Reliability

Point-to-Point Wire Replacement

Reliability and Durability

Repeatable Routings

Simplified Circuit Geometry

Flex PCB Static Application

An application where flexible circuits are flexed only to install the circuit and fit it into its application (also known as flex-to-fit or flex-to-install). A static application will typically be made using the less expensive Electro Deposited (ED) copper.

Flex PCB Dynamic Flexing Applications

A situation where the flexible circuit itself is dynamically (repeatedly) flexed during the actual use of the final product. Common examples include flip-type cell phones, laptops, printer heads and robotic arms. A dynamic application will require the use of Rolled Annealed (RA) copper.

High Density Flex PCB Applications

Flexible circuits allow for minutely narrow lines giving way to high density device population. Denser device populations and lighter conductors can be designed into a product, freeing space for additional product features.

With a large number of investments on the facilities of flexible printed circuit board and continuously innovating the flexible circuit board manufacturing technology, Hitech Circuits is able to manufacture flexible PCBs with a great variety of technologies, from simple single sided flex PCB, double sided flex PCB to complex multilayer flexible PCB, Rigid flex pcb and support prototype FPC with laser cutting & flying probe test to mass production with toolings.

Multilayer flex PCB bookbinding

Circuit bookbinding is one of the best practices employed by Hitechpcb engineers for creating stacked PCBs. For flex PCBs, we offered a 12 layer flex PCB board with bookbinding. An additional small length is added to the circuit, making it move in an outward direction from the bend radius. There are copper traces placed at right angles to the bend. This helps restrict the circuit bend in one direction.

The length to be added depends on total number of layers in the PCB, as well as the tightness of the bend. The advantage of circuit bookbinding is that it removes a great amount of tension from the various circuit layers during the bending process. The method also helps prevent buckling of the circuits at the exact bend radius.

The bookbinded PCBs can easily meet the tight tolerance requirements in comparison to bonded PCBs. This is why this 12 layer flex PCB is a perfect choice for applications where stricter tolerances are required. Its polyamide construction delivers immense strength and flexibility. This flexi PCB can easily perform 180° bends. Also, the construction helps prevent buckling of inner layers, which often occurs in a long term use. This flexibility also helps reduce stress on the internal components. This 12 layer flex PCB board has better shelf life than a 12 layer bonded circuit board. The immersion gold plating offers low contact resistance, good wetting, as well as excellent shelf life. We can provide the 12 layer flex PCB board with book binding in width 4/4 mil, with minimum finish thickness 0.15 mm flex and maximum 1.6 mm.

Advantages of Flexible PCB

Flexible PCB technology often has a wide range of possibilities for different designs and products.

The flexible feature is among the best attributes of the cables, wires, connectors and even PCBs.

Some of the advantages of using the flexible circuit include:

Reduces the overall weight and size.

A flex circuit can reduce the weight of a device by up to 70%.

Improves the packaging of electronics

It gives you the ability to solve interconnect and packaging issues as it can bend, form and move.

Interconnect solution as it reduces the amount of interconnects such as cables, wires, pcbs and connectors.

Conformability as the slender nature of the material allows for making of 3D packages

Electrical integration – You can easily come up with custom solutions basing your design on a plethora of choices of materials. Apart from that, you have the freedom to choose from the myriad of designs and plating procedures.

Heat dissipation ability or power – The polyimide dielectric has the ability to withstand very high temperatures. You can, therefore, use it for high power applications.

Electrical and mechanical repeatability

Cost saving as you can save up to 30% of the total cost of hand wiring and other assembly processes.

You can also save on space by almost 30%

It is more reliable as it does not have any wiring errors

Despite the numerous advantages, the flexible PCB also has its disadvantages.

Let’s have a look.

Disadvantages of Flexible PCB

Every electronic solution must have certain demerits.

Some of the disadvantages include:

Flexible PCB

A higher initial cost – Since the flex circuit is often custom for particular electronics. The initial cost of designing, photographic plate and layout is very high. This limits you to using it on large quantities to save on cost.

Flexible circuit repairs and changes are very difficult – The initial process is not just expensive but difficult to come up with. Once you have the base map, it becomes difficult to make any more changes. Removing and replacing the covering film for repair is also extremely difficult.

It is often small in size – The batch process of making the flexible circuits often limits the size of the flexible circuit. The production equipment limits you from making wider and longer sizes.

Easy to damage – Improper personal operations can easily damage the flexible circuits. Rework and soldering will require the expertise of a technician.

The process of assembly is also very difficult.

Do not let the disadvantages kill your spirits.

Why Not Make All Circuit Boards Flexible?

Flexible circuit boards are certainly useful, but they are not going to replace rigid circuit boards for all applications. Cost efficiency is the main obstacle to implementing an exclusively flexible circuit board design in a consumer product. Rigid circuit boards are less expensive to manufacture and install in a typical automated high-volume fabricating facility.

Typically, the ideal solution for an innovative product is one that incorporates flexible circuitry when necessary and employs solid, reliable rigid circuit boards where possible to keep manufacturing and assembly costs down.

Some manufacturers even use hybrid rigid-flex printed circuit boards expressly for this purpose. This is common in laptop computers and medical devices, where rigid circuit boards can be connected to one other using ribbon-like flexible circuits. These boards can be compounded and designed to meet any number of engineering needs by focusing on the respective strengths of each circuit board base technology.

Hitech Circuits creates both flexible and printed circuit boards for product manufacturers. Enjoy a consultation with one of our sales reps to find out if your product prototype design is best served by flexible or rigid circuit board types.

What is Flexible PCB and Its Production Process?

Flexible PCB (Flexible Printed Circuit, FPC) is very popular with excellent characteristics such as low weight and thin thickness, etc. It is also can be folded freely. Flexible PCB mainly relies on manual visual inspection with high cost and low efficiency. With the rapid development of the electronics industry, the design of printed circuit board has become more and more high -precision and high- density, traditional manual testing methods can no longer meet production needs. FPC defect automation testing has become an inevitable trend of industrial development.

Flexible printed circuit (FPC) is a technology developed by theUnited Statesto develop aerospace rocket technology in the 1970s. It is high reliability, excellent deflection made by polyester film or polyimide as a substrate material. A flexible circuit is formed by embedding a circuit design in a thin, flexible plastic sheet that is flexible, allowing a large number of precision components to be stacked in a narrow and limited space. This circuit can be bent and folded at will. Flexible has the characteristics like light weight, small size, good heat dissipation, easy installation, etc, it breaks through the traditional interconnection technology in the structure of the flexible circuit, the material is composed of insulating film conductor and adhesive

Flexible PCB includes single sided FPC, double sided FPC and multilayer FPC, etc. Single FPC has chemically etched conductive pattern layer, the conductive pattern layer on the surface of the flexible insulating substrate is calendered copper foil. The insulating substrate may be polyimide, polyethylene terephthalate, arylamide fiber ester and polyvinyl chloride. The double sided FPC on both sides of the insulating base has a conductive graphics made of etching, which increases the wiring density of the unit area. Metal hole connects the graphic connection on both sides of the insulation material to form a conductive pathway to meet the flexible design and function. The covering film can protect the single, double -sided wire and indicate the position of the component placed. According to demand, metal holes and coverage layers are optional. This type of Flexible PCB has fewer applications. Multi -layer flexible PCB is to press the single-sided or double-sided flexible circuit layer of 3 or more layers together. The metal hole is formed by drilling and electroplating, and conductive channels are formed among different layers. In this way, there is no need to use a complex welding process. Multi-layer circuits have huge functional differences in higher reliability, better thermal conductivity and more convenient assembly performance.

At present, the production process of flexible PCB mainly includes looping, Sizing conductor, etching, routing of the conductors, ground planes, sizing of the holes, filleting, button plating, adhesive-backed films, screen-print liquid overcoats, photo imaginable liquid, film polymers and other processes. See the figure for the specific production process.
