FR4 PCB
PCBA is a process requiring knowledge covering PCB manufacturing assembly, PCB design, fabrication and a strong understanding of the final product. ZF is a professional pcb manufacturing companies with high-quality, all of our products have obtained ISO9001, ISO13485:2016, IATF16949:2016, IPC-A-610E, UL, RoHS certifications. PCBs have long been an essential part of electronic circuits. As a result, most of the electrical engineers involved in the production of these boards are familiar with the different materials used to manufacture them. FR4 is one of the most popular materials used by fr4 pcb manufacturer. What makes it popular? You will find information about the FR4 material used in fr4 printed circuit board down below. Introduction to FR4 PCB material FR in FR4 denotes flame retardant and FR4 distinguishes the material from other materials in the category. The glass pcb fiber fr4 structure provides structural stability to the material. The glass fiber layer is covered with a flame retardant epoxy resin, which brings durability and robust mechanical properties to the material. All these characteristics make fr pcb popular among electronics manufacturers. Advantages of the popularity of FR4 PCBs 1. FR4 is a low-cost material. 2. It has a high dielectric strength, which contributes to its electrical insulation properties. 3. The material has a high strength-to-weight ratio and is lightweight. 4. It is moisture-proof and also has a relative temperature. 5. It has an excellent electrical loss performance. 6. FR4 does not absorb water and is therefore also suitable for various marine PCB applications. 7. The material is yellow to light green and is ideal for any application. All these features make it suitable for a wide range of environments. How is FR4 organized on a conventional FR4 PCB? FR4 can act as the base for any PCB. The material is laminated with a copper foil layer, which is laminated using heat as well as an adhesive. The copper foil can be used to laminate the material from one or both sides. Tips for choosing the right FR4 material for your FR4 PCB It is vital to use the correct thickness of material for the construction of FR4 PCBs. Thickness is measured in inches, such as inches, feet, and yards. There are several elements to consider when selecting pcb material fr4 for your PCB. The following tips will simplify your selection process. 1. Select thin FR4 material for building panels with space constraints. The thin material can support the various precision components needed to make devices such as Bluetooth accessories and USB connectors. They are also suitable for larger projects where engineers wish to focus on space-saving design. 2. The thin FR4 material is suitable for applications where flexibility is required. For example, using the thin material for automotive and medical PCBs is ideal as these PCBs need to be bent regularly. 3. Avoid choosing thinner materials for PCB designs with recesses as it increases the risk of damage or fr4 pcb board breakage. 4. The thickness of the material affects the weight of the fr4 circuit board and may also affect the compatibility of the components, which means that a thin FR4 material would logically facilitate the manufacture of lighter boards and thus the production of lighter electronics. These lightweight products are attractive and easy to transport. When to avoid using FR4 PCB material? FR4 material is not the right choice if your application requires any of the following. 1. Excellent heat resistance. If PCBs are required to be applied in high- temperature environments, it is recommended that FR4 materials are not used. For example, for PCBs in aerospace applications, FR4 material is not the right choice. 2. Lead-free soldering. If your customer requires a RoHS compliant PCB, lead- free soldering must be used. During lead-free soldering, reflow temperatures peak and reach 250 degrees Celsius and are not tolerated by FR4 materials due to their low-temperature resistance. 3. High-frequency signals. When exposed to high-frequency signals, FR4 boards are unable to maintain a stable impedance. As a result, fluctuations can occur and may affect the integrity of the signal. Due to their popularity and widespread use, it is easy to find FR4 PCB materials on the market today with a wide range of specifications and functions. Such an abundance of choice can sometimes make selection difficult. In such cases, it is essential to discuss your requirements with the manufacturer. Minimum Order: 1 bags Contact:

Application of flexible PCB Aerospace Military Mobile communications Laptop computers Computer peripherals PDAs Digital cameras More Types of flexible PCB 4. Substrate to generate double-sided board Two layers of single-sided PI copper-clad plate materials are used to compress the board, supplemented by adhesive for a window opening at a specific position, so as to become a double-sided conductor circuit board with a two- layer separated structure in a local area to achieve a circuit board with high flexural performance in the stratified area. (1) Single sided board To form a single layer flex pcb coverlay board, the single-sided PI copper clad plate is used to form a flexible circuit board with a single layer of conductors by covering it with a protective film after the circuit is completed. (2) Ordinary double sided board For double sided printed circuit boards, after the double-sided circuit is completed with double-sided PI copper clad plate, the protective films are added on both sides to make a circuit board with double-layer conductors. (3) Single sided board generated by substrate A pure copper foil material is used in the circuit manufacturing process where a protective film is added to each side of the PCB to make a circuit board with only a single layer of conductors which, however, are exposed on both sides of the PCB. (4) Double sided board generated by substrate Two single-sided copper PI boards are compressed with a bonding adhesive at a specific location to form a double-sided conductor board with a lamination in one local area and a separation of the two layers in other local area to achieve a board with high flexural properties in the layered area. Advantages of flexible PCB: Good heat dissipation and excellent solderability, easy assembly and connection and low overall cost. That's why you would consider flex PCB when you buy the PCB board. The base material is mainly polyimide copper clad laminate, which has high heat resistance and good dimensional stability. It can be pressed with a cover film with mechanical protection and good electrical insulation properties to form the final product.

ZF is a professional pcb manufacturing companies with high-quality, all of our products have obtained ISO9001, ISO13485:2016, IATF16949:2016, IPC-A-610E, UL, RoHS certifications. The double layer pcb china(double-layer/double-sided printed circuit board/breadboard) is more complicated than single sided PCB. The circuit patterns, on both sides, are connected through a through-hole in the middle. Various types of double-sided PCB are on the market, such as double sided copper clad PCB, high Tg thick copper foil PCB, high-frequency PCB, and hybrid dielectric base high-frequency double-sided PCB. Double-sided PCBs are widely used in high-tech industries like telecommunications, power supply, computers, industrial control, digital products, scientific and educational equipment, medical equipment, automobiles, aerospace defense. The production process of double sided PCB Double-sided or 2 layer PCB is usually made of epoxy glass cloth copper-clad laminates. It is mainly used for communication electronic equipment, advanced instruments, and electronic computers with high-performance requirements. The production process of two sided PCB can be generally divided into several methods, such as process wire method, hole plugging method, masking method, and pattern plating-etching method. Advantages of double layer PCB As one of the professional PCB fabrication companies in China, ZF Electronics will introduce some features of double layer printed circuit board: It makes it relatively easy to add conductive paths on the board, which means you will have a PCB that better suits your needs. As both sides are conductive, a large number of ICs and components can be assembled at any time. You can add more components as needed as there is an extra layer. More space and flexible design allow the PCB to suit your requirements. Dual layer PCB is ideal for demanding applications and advanced electronics. If necessary, the size of the double-sided PCB can be reduced, because double sides can be used. This type of printed circuit board for sale may save you money because you may only need one. Double-sided PCBs can be used in many different applications and electronic products, suitable for a wide range of industries. The difference between double sided PCB and single sided PCB Appearance: A single sided circuit board only has one layer, but the double- sided PCB has 2 layers, with a via hole connecting double sided PCB circuit.

Buried Via PCB
PCBA is a process requiring knowledge covering PCB manufacturing assembly, PCB design, fabrication and a strong understanding of the final product. ZF is a professional pcb manufacturing companies with high-quality, all of our products have obtained ISO9001, ISO13485:2016, IATF16949:2016, IPC-A-610E, UL, RoHS certifications. A buried via is a connection of any circuit layer inside the PCB but not connected to the outer layer. The via cannot be drilled after bonding because it must be drilled on the individual circuit layers first. After partially bonding the inner layer, it has to be plated before finishing the bonding, which is more laborious and therefore more expensive than the original through via and blind via. Usually, it is only used in high-density(HDI) PCB to increase the available space for other circuit layers. 1. What is via? The via is an important factor in the design of multi-layer PCB and consists of three main parts, including drill hole, the pad around the hole and the POWER layer. When talking about its process, it should be firstly plated a layer of metal by chemical deposition on the cylindrical surface of the via wall to connect the copper foils that need to be connected to the middle layers. The upper and lower sides of the via will be made into a common pad shape, which can be directly connected with the lines near the two sides or not. 2. Classification of vias by function In terms of function, vias can be divided into two categories. One is used for electrical connection between layers while the other is used for fixing or positioning devices. As for the process, the vias can be generally divided into blind via, buried via and through via. (1) Blind via Blind via hole is located on the top and bottom surfaces of the PCB with a certain depth. It is used to connect the line on the surface and the underlying inner line and its depth usually does not exceed a certain ratio (aperture). (2) Buried via It refers to the connection via that is in the inner layer of buried via PCB which will not extend to the surface of the circuit board. Both of above-mentioned two types of vias are located in the inner layers of the circuit board, which are completed by using a through-via forming process before lamination. There may also be several inner layers overlapping during the via formation process. (3) Through via The through hole vias penetrate the entire circuit board and can be used for internal interconnection or as a positioning via of component installation. Because of its easier implementation and lower cost in the process, most of the PCBs use it instead of the other two kinds of vias. The advantages of the blind via and buried via In the non-through-via technology, the application of blind via and buried via can greatly reduce the size and weight, as well as the number of layers and costs in printing circuit boards, moreover, improve the electromagnetic compatibility, increase the characteristics of electronic products, making the design simpler and faster. As for the traditional PCB design and processing, there are many problems brought by through vias. First of all, through-vias occupy a large amount of effective space. Secondly, a lot of through-vias densely packed in one place also make the wiring of the inner layers in the multilayer PCB difficult. That is because they will take up the space required for alignment, destroy the impedance characteristics of the power supply and make the power ground plane ineffective. What's worse, the conventional mechanical method of drilling will be 20 times the workload of non-through hole technology.

Blind Via PCB
ZF Electronics, as one of the top custom circuit board manufacturers and pcb manufacturing companies in China, can provide customers with single-sided PCB, double-sided FR4 PCB, metal core PCB, heavy copper PCB, rigid PCB and rigid- flex PCB. As the name suggests, blind via cannot be seen. Blind via buried viais the via that connects the surface layer and the inner layer without penetrating the entire board. In order to increase the space utilization of the PCB circuit layer, the blind via is produced. Blind via in pcb is located on the top and bottom surfaces of the printed circuit board and has a certain depth. It is used to connect the surface circuit and the underlying inner circuit and the depth of the hole usually does not exceed a certain ratio (aperture). How to manufacture blind via PCB? The hdi vias PCB production method requires special attention to the depth of the drilling (Z-axis) to be just right. If you do not pay attention to it, it will cause difficulties in electroplating in the via, so almost no factory adopts it. You can also put the circuit layer that needs to be connected in advance in the individual circuit layer. The blind and buried vias are drilled first, and then glued together, but more precise positioning and alignment devices are required. The line width and line spacing of most process equipment: blind via 0.1mm, 0.125mm, 0.15mm. Difference between blind via and plating through blind via hole PCB From the processing point of view, through hole circuit board PCB and blind via and buried via hole PCB have different requirements for cutting tools in terms of chip removal ability. The processing of blind buried vias makes it easy for the cutting tool to be buried in iron chips, so better chip removal performance is required. It is better to use spiral flute taps to machine blind holes, instead of straight flutes, it is easy to block chips and cause tool breakage. For drilling and blind hole processing, it is best to use an internally cooled central water outlet drill bit. With the central water outlet effect of the machine tool, the iron filings can be forced off by the coolant pressure, so that the iron filings will not be entangled and blocked, which leads to over- tolerance in machining and breakage of tools. The boring is the same as the drilling, and it is best to use the center outlet. But the above statement is not absolute espeically when you want custom made pcb boards. It mainly depends on the depth-to-diameter ratio of the blind via aspect ratio. If the shallow hole is processed, it can also be used as a general plating through hole PCB processing tool.

Aluminum PCB
ZF Electronics, as one of the top custom circuit board manufacturers and pcb manufacturing companies in China, can provide customers with single-sided PCB, double-sided FR4 PCB, metal core PCB, heavy copper PCB, rigid PCB and rigid- flex PCB. With excellent electrical properties, heat dissipation capability, electromagnetic shielding, high dielectric strength and resistance to bending, aluminum substrates are widely used in many industries such as high-power LED lighting, power supplies, TV backlighting, automotive, computer, air conditioning inverter modules, avionics, telecommunications, medical and audio. When it comes to cell phone cameras which are the most commonly used in our daily life, aluminum pcb factoryis of great importance. As a aluminum pcb china (MCPCB), aluminum foil circuit board/aluminum printed circuit board has many similarities with FR4 PCB in terms of manufacturing process or technology, including thick copper foil etching, aluminum surface etching protection, aluminum PCB board manufacturing and solder resist film printing. Since the 1970s, aluminum PCBs were first used in power amplification hybrid ICs and have become popular. Due to the development of LED industry in recent years, the application and trend of them are increasingly widespread together with the boost of aluminum PCB manufacturers or factories in China. Therefore, in order to better utilize them in the product and industry, it is necessary to understand some important characteristics of the PCBs. Structure of Aluminum PCB In terms of the structure, it truly shows the structure of aluminium board pcb CCL, different from the metal core board, consisting of copper foil, dielectric layer, aluminum base and aluminum base film (which is optional). (1) Copper foil layer The aluminum CCL has the same copper foil layer as the ordinary one. The circuit layer requires large current carrying capacity, which is the reason for changing thicker copper circuits from 1 ounce to 10 ounces. The back of the copper foil must be chemically oxidized while the surface should be zinc-plated and brass-plated to improve the peel strength. (2) Dielectric layer The dielectric layer consists of a layer of thermally conductive dielectric material with low thermal resistance and a thickness of from 50μm to 200μm, which is the core technology of aluminium clad pcb CCL. It excels in resistance of heat and aging and can withstand mechanical and thermal stress. (3) Aluminum base The aluminum base is actually the aluminum substrate material and is the support component. It requires a high thermal conductivity to be suitable for general mechanical engineering, such as drilling, punching and cutting. (4) Aluminum base film The aluminum base film serves to protect the the surface from scratches and etchants. The films can be classified as normal one (below 120°C) and high- temperature-resistant one (250°C). The latter type can meet the requirements of HASL as a surface finishment. Aluminum PCB performance (1) Heat dissipation Compared to normal FR4 PCBs, the aluminum PCBs perform better and more quickly in heat dissipation than most of other PCB printed circuit board. Take the FR4 PCB and the aluminum PCB with the same thickness of 1.5mm as an example. FR4 PCBs have a thermal resistance of from 20°C/W to 22°C/W while aluminum PCBs have it of from 1°C/W to 2°C/W, which proves the feature again. (2) Thermal expansion The thermal expansion and contraction are common properties of substances but have different coefficients. Because of the excellence in heat dissipation of the aluminum PCBs, the problems on the thermal expansion and contraction on the board surface will be significantly reduced to increase the durability and reliability of the entire equipment and electronic devices. This kind of advantages can be particularly suitable for the thermal expansion and shrinkage problems of surface mount technology (SMT). (3) Dimensional stability The aluminum PCBs have significantly stable dimensions. Their dimensions will only change about 2.5% to 3.0% when they are heated from 30 ℃ to 140 ℃ or even 150 ℃. (4) Other performance a. Applicability to power device SMT. b. Effective thermal expansion of circuit design. c. Helpful to reduce operating temperature, improve product power density and reliability, and extend the shelf life of products. d. Helpful to reduce the size of the product, hardware and assembly costs. e. Easy replacement of fragile ceramic substrates with better insulation performance and mechanical durability.

Layer PCB
ZF Electronics, as one of the top custom circuit board manufacturers and pcb manufacturing companies in China, can provide customers with single-sided PCB, double-sided FR4 PCB, metal core PCB, heavy copper PCB, rigid PCB and rigid- flex PCB. 4 layer pcb board is laminated on the basis of double-sided PCB, PP and copper foil are added on both sides of the double-sided PCB. Usually, the layout of the4 layer PCB is signal wire-ground wire-power supply-signal. Production of 4 layer PCB 4 layer PCB/four layer pcb is made by lamination on the basis of the double sided PCB. During the lamination, copper foil and PP are added to the two sides of the double-sided PCB, and then the cheap 4 layer pcb is formed by high- temperature pressing. Some people would ask: what is the difference between double sided PCB and four layer PCB? The cropped double sided PCB can be drilled directly on the machine without lamination, while the 4 layer PCB will enter the lamination process after some circuits are etched in the inner layer. Finally, drill holes can be made after lamination. What are the common rules for designing a 4 layer PCB? (1) Line width: Usually, the signal line is set up 6mil, and the remaining power lines are 5V and 3.3V or it can be set up 10mil, 20mil respectively. (2) Vias: Normally, there are about 2-3 types of vias on a 4 layer flex pcb product. The designed conductor width and conductor spacing should take the production process capability of the 4 layer pcb manufacturer into consideration. If the conductor width and conductor spacing we designed are over the production capacity of the partner, it may increase unnecessary production costs, and even need to change the supplier. Therefore, when designing the conductor width and conductor spacing, we should basically control it at 4/4mil and the via 12mil, then the PCB 4 layer board supplier above 85% are able to put them into production. The conductor width and conductor spacing here refer to the size between elements such as line-to-hole, line-to-line, line-to-pad, line-to-via when setting rules. The setting rules consider the design bottleneck in the design file. If there is a 1mm BGA chip, its pin depth is relatively shallow, and only one signal line is needed to be set between two rows of pins and it can be set to 6/6mil. If pin depth is relatively deep, two signal lines need to be taken between the two rows of pins and it can set to 4/4mil. If there is a 0.65mm BGA chip, it needs to be changed to HDI blind via design. Generally speaking, if it is larger than the design bottleneck, then the regional rules can be set. Local line width and moment are designed to be smaller and the other places on the board could be larger to facilitate production and improve the qualification rate. (3) Copper foil: Under normal circumstances, modifications can be made.
