In PCB design, adopting appropriate wiring forms has a significant impact on the performance and reliability of the circuit. The following are several common wiring forms, each with its own advantages. Choosing the appropriate form based on specific design requirements will be more conducive to improving circuit performance and reliability. 1. Straight line routing: Straight […]
（1）. Environmental protection 1. Keep the board surface dry: Excessive humidity can cause electrochemical reactions, oxidation and corrosion in multi-layer board circuits, and even cause short circuits in severe cases. Therefore, the environmental requirements for using PCB multi-layer circuit boards are relatively high, so try to keep the environment dry. 2. Pay attention to dust […]
1. Corrosion resistance Immersion gold PCB has excellent corrosion resistance. Its surface metal coating can effectively prevent the PCB board from being corroded by the external environment. Compared with other surface treatment processes, immersion gold PCB can better resist oxidation, sulfuration and chemical corrosion, thereby extending the service life of the circuit board. 2. Reliability […]
Via hole is one of the important components of multi-layer PCB, and the cost of drilling usually accounts for 30% to 40% of the PCB board manufacturing cost. Simply put, every hole on the PCB can be called a via. From a functional point of view, vias can be divided into two categories: one is […]
High-speed PCB boards, as the name suggests, refer to PCB boards used in high-speed circuits, generally used in communications, computers, military and other fields. High-speed PCB board is a widely used electronic component that has excellent performance in high frequency, high-speed transmission, signal integrity, etc. So what exactly does high-speed PCB mean? In fact, it […]
PCB impedance board is an indispensable part of modern electronic manufacturing. It plays an important role in circuit wiring, signal integrity, power consumption control and EMI anti-interference. By controlling the impedance value and optimizing the circuit design, the signal transmission quality can be improved, power consumption can be reduced, and the reliability and anti-interference ability […]
The combination of Rigid-Flex circuit boards refers to the combination of software and hardware in circuit board design to achieve more efficient and stable circuit functions. 1. Improve production efficiency The design of the Rigid-Flex circuit board can reduce the wiring length while making the connections between circuit components closer, thereby reducing electromagnetic interference and […]
Thick copper PCB is a high-performance PCB that is widely used in high-power electronic devices due to its unique performance and characteristics. 1、 Good thermal conductivity The copper layer thickness of thick copper PCBs is relatively large, usually reaching 10oz in the inner layer and 6oz in the outer layer, which is much thicker than […]
If analog circuits (radio frequency) and digital circuits (microcontrollers) work alone, they may work well, but once they are put on the same circuit board and work together using the same power supply, the entire system is likely to be unstable. . This is mainly because the digital signal frequently swings between ground and positive […]
PCB layout requirements refer to the guidelines and specifications that must be followed when designing a printed circuit board (PCB). These requirements ensure the successful function, efficiency and reliability of the board. The following are some common PCB layout requirements: 1. Component placement: Components should be arranged in such a way as to minimize signal […]
