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.

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.

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.

We will reply within one workday. We will continue to provide quotation support and design support. Welcome to learn about our production process.
