A NEW TYPE OF WIRE BOARD——RIGID FLEX PCB
https://www.speedapcb.com/rigid-flex-pcb/
Tumblr media
Rigid-flex PCB is a new type of wire board with both hard and soft boards. The hardboard has the same thickness and strength as the PCB board. It can mount electronic components and withstand certain mechanical forces. Parts are usually used to achieve three-dimensional installation.
 The use of flexible boards allows the entire flexible and rigid board to be partially bent. Rigid-flex PCB meets the needs of today's electronic products in the direction of high density and high reliability, miniaturization, and lightweight, and also meets strict economic requirements and the needs of the market and technological competition. Flexible circuits have gained tremendous popularity recently because they can be shaped, bent, twisted, and folded into infinite configurations.
 However, in the end, rigid-flex PCB serves the same ultimate function in the most basic sense, connecting various electrical and mechanical components together.

WIRING ON THE DOUBLE-SIDED BOARD——DOUBLE SIDED PCB
https://www.speedapcb.com/double-sided-pcb/
Tumblr media
There are wiring on both sides of the dual layer PCB, but to use the wires on both sides, you must have a proper circuit connection between the two sides. This "bridge" between circuits is called a via. A via is a small hole filled or coated with metal on the PCB. It can be connected to the wires on both sides. Because the area of the double-sided board is twice as large as the single-sided board, the dual layer PCB solves the difficulty of wiring interleaving in the single-sided board (which can be conducted to the other side through the hole), and it is more suitable for more complicated circuits than the single-sided board.
 Features of Double Sided PCB
 Double Sided PCB
SPEEDAPCB is a professional PCB supplier. We can provide customers with a one-stop service from PCB design to PCB production and assembly.
 As a professional PCB manufacturer, we have 10 PCB production lines to manufacture double sided PCB board prototype. The machine works 24 hours a day, only to provide customers with satisfactory delivery time.
 Double Sided PCB
Our PCB boards can be divided into single-panel double-panel and multilayer boards according to their structure. The double sided PCB board is a board with double-sided wiring on the board. An important feature of the double sided prototype PCB is that it has a guide hole to connect the wires on both sides into a circuit.
 Double Sided PCB
The double-panel wiring can be staggered with each other, which is the biggest difference from a single-panel; the double-panel is more suitable for complex circuits and has a wider range of use.
 Double Sided PCB
The cost of single and double panels is not much different. If there is no special requirement, all industries will give preference to double panels; after all, the performance and stability of double panels are better than single panels.

4 Layer PCB
https://www.speedapcb.com/4-layer-pcb.html
Tumblr media
In general, in a 4 layer PCB, both the top and bottom layers belong to the signal layer, while another two inner layers are GND and VCC. If the first inner layer has several GND planes, the blank areas of which should be filled with copper. It could also have some routings, but do remember these routings are not allowed to cross the copper area. Same to the second layer with several powers. Usually, layers of a 4 layer PCB are connected by plated through holes, buried holes, and blind holes while layers of a 2 layer PCB are only connected by plated through holes. Besides, if possible, VCC and GND should not serve as signal layers.
 There are insulation materials between the two layers. After every layer is printed with circuits, we could use lamination to make circuits overlap and use drills to make via holes to connect circuits. Since a 4 layer, PCB has routings in several layers, it is a good choice if you want to design elaborate products in small sizes, like mobile phone circuit boards, mini-projectors, and recorders. In addition, multi-layers provide broader space for design, control differential characteristic and single-ended impedance, and better the output of signal frequency.
 Right now, our electronic devices continue to pursue higher speed, larger capacity, and smaller size. Therefore, 4 layer PCB is a product that emerges as the times require. Later plated through holes, buried holes and blind holes come into being to meet people’s needs to produce circuit boards with greater density, precision. Now that computer and aerospace industries are in great need of high-speed circuits, they are asking for components with higher packaging density. Besides, discrete components are getting smaller, microelectronics is facing rapid development, and electronic devices are turning into smaller and lighter ones. With such background, the single-sided or double-sided printed boards are not capable to increase the packaging density because they have restrictions brought up by limited space.

Blank PCB
https://www.speedapcb.com/blank-pcb.html
Tumblr media
Blank PCB is a printed circuit board, also called printed wiring board, which is an important electronic component, the support of the electron component, and the supplier of the electrical connection for the electron component. Since it is made with electron printing, it is called a "printed" circuit board.
 As the electronic instruments become more and more complicated, the parts they need become much more accordingly, and the circuit and the parts on the board become denser. The blank PCB (without parts on) is often called the "Printed Wiring Board (PWB)". The substrate of the board is made of materials with attribution of insulation, thermal insulation, and inflexibility. The tiny wires can be seen on the surface is the copper foil which had been covered the whole board, but partially etched, then the remaining part formed the tiny netted wires. And these wires are called conductor pattern or electric wiring, which is used for offering the electrical connection for parts on PCB.
 Generally, the color of the PCB is green or brown, which is the color of the solder mask. It is the protective layer of insulation to protect the copper foil and preventing the parts from being soldered onto the incorrect positions. Silkscreen will be printed on the solder mask where words and marks (mostly white) will be printed in order to highlight each position of the parts. The silkscreen is also called a legend.

Through hole pcb
https://www.speedapcb.com/through-hole-pcb/
Tumblr media
PLATED THROUGH HOLE PCB / PTH PCB
 There are three common types of drilled holes in the printed circuit board: PCB through hole plating, blind via hole, and buried via hole. Therefore, PCBs are classified according to drilling methods and can be divided into plated through-hole PCB, blind via hole PCB, and Buried via hole PCB.
 PTH is the most common drilling method, and it is common in various types of PCBs. SPEEDAPCB has been focusing on the production of various PTH (plated through hole PCB-PTH PCB), buried via hole PCB and blind via hole PCB.
 Drilling Method of Plated Through Hole PCB
 Through Hole PCB
Plated Through Hole, the copper foil lines between conductive patterns in different layers of the circuit board are connected or connected with this type of hole, but the copper legs of the component lead or other reinforced materials cannot be inserted. The PCB is formed by the accumulation of many copper foil layers. The copper foil layers cannot communicate with each other because each layer of copper foil is covered with an insulating layer, so they need to rely on via for signal connection.
 Through Hole PCB
The through hole of the circuit board must pass through the plug hole to meet the customer's needs. In changing the traditional aluminum sheet plugging process, the solder mask and plug hole on the circuit board surface are completed with a white net to make its production more stable and the quality more reliable , More perfect to use. The vias help the circuits to be connected to each other. With the rapid development of the electronics industry, higher requirements are also placed on the PCB manufacturing process and surface mount technology. The plugging process for vias came into being, and at the same time, it must meet the following requirements:
 1. Only copper is required in the hole, solder plug can be plugged or not;
 2. There must be tin-lead in the hole, with a certain thickness requirement (4um), to avoid solder mask ink entering the hole, causing tin beads to be hidden in the hole;
 3. The through hole must have a solder resist ink plug hole, opaque, no tin rings and beads, and must be flat.
 Through Hole PCB
Through-hole boards are common in all fields and are one of the most common PCBs.
 Generally, the mobile phone board or PDA board has a board that uses a combination of blind and buried holes. The buried hole can reduce the probability of signal interference, maintain the continuity of the transmission line's characteristic impedance, and save routing space. Circuit board design. This type of board requires high technical content and accurate accuracy, so relatively speaking, the requirements for factory equipment are much higher than ordinary multilayer boards, and the cost of such circuit boards will be much higher than ordinary Shelf should be high.

Single sided pcb
https://www.speedapcb.com/single-sided-pcb/
Tumblr media
THE MOST BASIC CIRCUIT BOARD——SINGLE SIDED PCB
 Single-Sided Boards are the most basic PCB, the parts are concentrated on one side, and the wires are concentrated on the other side (when there are chip components, the same side as the wire and the plug-in device is on the other side). Because the wires only appear on one side, this type of PCB is called Single-sided (also known as one sided PCB). Because the single panel has many strict restrictions on the design circuit (because there is only one side, the wiring cannot cross and must go around its own path), only early circuits used this type of board.
 Features of Single Side PCB/Single-sided PCB
 Single Side PCB/Single-sided PCB
The single sided PCB is the most basic circuit board of the PCB industry. The single sided PCB as the name implies is that the wires are on one side and the plug-in parts are on the other side. PCB single panels were widely used in various industries in the early days. However, due to the high wiring requirements of single side PCB, each line must have a separate path and cannot cross.
 Single Side PCB/Single-sided PCB
For single sided flex PCB with many wirings, the stability is not enough and the performance is also missing. Gradually develop towards dual panels. Therefore, the usage rate and yield of PCB single panels are gradually decreasing; at present, PCB single panels are used more in power supply boards.
 Single Side PCB/Single-sided PCB
The single-panel wiring diagram is mainly screen printing, that is, a resist is printed on the copper surface. After etching, it is marked with a solder resist. Finally, the part guide hole and punching process are completed. shape. In addition, some small and diverse products use a photoresist to form patterns.

OSP differs from other surface treatment processes in that it functions as a barrier layer between copper and air; in short, OSP is a chemically grown organic film on a clean bare copper surface. This film has anti-oxidation, thermal shock resistance, and humidity resistance to protect the copper surface from rusting (oxidation or sulfurization) in the normal environment. At the same time, it must be easily assisted in the subsequent welding high temperature. The flux is quickly removed for soldering. An osp pcb is an organic solderability preservative board.
 The general process is: degreasing-> micro-etching-> pickling-> pure water cleaning-> organic coating-> cleaning. The process control is relatively easy compared to other methods.
 OSP PCB
Currently, about 25% -40% of PCBs use organic coating processes, and this proportion has been rising. The organic coating process can be used on low-tech PCBs as well as on high-tech PCBs, such as single-sided TV PCBs and high-density chip packaging boards. For BGA, there are more organic coating applications. If the PCB does not have surface connection functional requirements or storage period limitations, organic coating will be the most ideal surface treatment process.

MORE PRINTED CIRCUIT LAYERS BOARD——MULTILAYER PCB
https://www.speedapcb.com/multilayer-pcb/
Tumblr media
A multilayer printed circuit board has more layers than a double-sided printed circuit board. It has many circuit layers between the top and bottom surfaces of the printed circuit board, and each layer can be connected through PTH (plated through holes). This type is more complicated than a double-sided printed circuit board.

SPEEDAPCB has been focusing on various single side PCB, double-sided PCB, and multilayers PCB manufacturing.
 Multilayer PCB
PCB multilayer board simply means that more single and double boards are used to alternate the insulation material and the positioning system, and then the lines are interconnected to form a multilayer circuit board. For example, one double board is used as the inner layer and two single boards are used as the inner layer. The inner layer is a four-layer board formed by technology.
 Multilayer PCB
The design of the multilayer board is more flexible and the electrical performance is more stable and reliable. At present, the most multi-layer boards used in various industries are still four or six-layer boards, and the consumer electronics industry uses more high-level PCB boards.

Electronics makes a significant contribution to the health-the nursing industry, as a diagnostic, monitoring, and treatment device. As the development of electronic products becomes more efficient and denser, the medical applications of these electronic devices continue to grow, bringing endless new possibilities.
  The heart of these medical devices is the PCB. PCBs in the medical industry is highly specialized to accommodate the unique limitations of medical devices. In many medical applications, small packages are required to meet the size requirements of implants or emergency room monitors. Therefore, medical PCBs are often special high-density interconnect PCBs, also known as HDI PCBs. Medical PCBs can also be made from flexible substrates, making the PCB bend during use, which is essential for both internal and external medical equipment.
  Due to the health issues associated with them, medical care maintains higher standards in PCBs than most other PCB types. In addition to meeting strict medical regulations, repeatability and reliability are two basic qualities that medical PCB suppliers must achieve.
  Medical PCB applications are growing as fast as the medical device industry itself. Some of the most common medical PCB applications include:
 Monitors: Personal and healthcare monitors, including blood glucose monitors, heart rate and blood pressure monitors, etc.
 Scanning technology: CT scanners and ultrasound technology often use PCB-based electronics.
 Control system: The device controls the infusion, and the flow rate and distribution are electronically controlled.
 Internal equipment: Pacemakers and similar internal medical equipment keep patients healthy and are operated by a trace PCB in the center.
 Scientific instruments: Medical research uses a large number of scientific instruments to study disease and test patient outcomes. These include electron microscopes, photometers, and generator and compressor control systems.

Military PCB Manufacturer & Assembly
https://www.speedapcb.com/military-pcb.html
Tumblr media
 Today, printed circuit boards are commonly used in the military and aerospace industries. Military and aerospace products require printed circuit boards with high reliability under extreme conditions. Any electronics used for flight or combat must be rugged, reliable, and compact. Military and aerospace-related electronics typically require a 50-year lifespan and need to be able to operate for decades. Because their role is so critical, the printed circuit boards they use often have higher standards than ordinary printed circuit boards,
 Military and aerospace-grade PCBs are the most rugged, efficient, and reliable printed circuit boards on the market. These military printed circuit boards are often subjected to high pressure and pressure, which means that they will often require high-temperature substrates, such as high-temperature resistant laminates, copper, or aluminum. Military PCB manufacturers must produce PCBs that are resistant to thermally induced oxidation and designed to dissipate heat efficiently at a low weight.
 SPEEDAPCB provides PCB boards for sale, we have high-quality, durable, heat-resistant PCBs for a variety of military and defense applications. If your military or defense application requires a high-quality printed circuit board, SPEEDAPCB may be a smart and cost-effective option.

Large & Small PCB
https://www.speedapcb.com/large-small-pcb.html
Tumblr media
 Nowadays, the reduction of the size of the basic printed circuit board will reach half or the quarter of the original size. The extremely thin wires that designers couldn't use before are now the mainstream, and the thinnest wire with 75 micrometers (3 mils) has gradually been reduced to 30 micrometers (1.2 mils) or even thinner.
   Manufacturers of a sophisticated microcircuit can be divided into four groups. The first group is in the Asian area, which has developed the unique thin wire process for phones or iPods and can arrange wires of 40-50 micrometers. The second group consists of the research and development companies of limited numbers which produce small numbers of very professional circuits with thin wires of less than 40 micrometers.
 The third group is expanding its business of large and medium-sized PCB with the highest speed. They provide a little output with wires of 75-40 micrometers in width, and they can produce several thousand within weeks. At last, the fourth group produce PCB normally with the wires of 125-75 micrometers and includes a large number of manufacturers and participants.
 As the microelectronics business expands, more and more PCB companies find out the necessary technology in producing the very thin wires with a width of 40 micrometers, and even less than it, circuit designers need to be familiar with the new design rules and the merits and demerits of microelectronics manufacturing.

LEAD FREE HASL PCB / IMMERSION TIN PCB
https://www.speedapcb.com/lead-free-hasl-pcb/
Tumblr media
Lead-free HASL is to coat a layer of tin-lead alloy on the copper surface to prevent the oxidation of the copper surface and provide a good welding base for the subsequent assembly process. What is hot air leveling? It is actually a process of combining dip soldering and hot air leveling, and coating eutectic solder in the metallized holes of lead-free printed circuit boards and printed wires. The process is to first dip the lead-free printed circuit board with flux, then dip the molten solder, and finally pass between the two air knives. Use the hot compressed air in the air knife to remove the excess on the printed board The solder is blown off, and at the same time, the excess solder in the metal holes is eliminated, thereby obtaining a bright, smooth and uniform solder coating.
 The immersion tin process can form a flat copper-tin intermetallic compound. This feature makes the immersion tin have the same good solderability as hot air leveling without the troublesome flatness problems of hot air leveling; nor does it have electroless nickel plating / Diffusion issues between gold and metal; just the tin immersion board cannot be stored for too long.
 Lead Free HASL PCB
Immersion tin does not bring any new elements into the solder joint, which is especially suitable for communication backplanes. The use of the immersion tin board is restricted due to the inconvenience of storage and the carcinogens contained in the process. About 5% -10% of PCBs currently use a dip tin process.
 Parameters of Lead Free HASL PCB
1. Prevent oxidation of bare copper surface; 2. Maintain solderability
 SPEEDAPCB has a mature HASL production line, as well as particularly experienced engineers, we will do our best to provide you with the perfect plate making service.

 The most prominent advantage of solder coating with hot air leveling is that the coating composition always remains the same, and the edges of the printed circuit can be completely protected.
 The cost of hot air leveling is lower than other surface treatments, the process is mature, and the weldability is good.
