In any switching power supply design, the physical design of the PCB board is the last step. If the design method is improper, the PCB Design may radiate too much electromagnetic interference, causing the power supply to work unstably. The following is the analysis of the matters needing attention in each step. pcba 1. PCB […]
How many layers are the best for PCB design? One article will help you understand the meaning of PCB layers. PCB has many layers. When beginners begin to learn PCB design, they are easily confused by various layers. To this end, we have made a summary of the layers in the PCB to help you […]
Recently, the generative model led by ChatGPT has become a new hotspot of AI. Microsoft and Google in Silicon Valley have invested heavily in such technology (Microsoft has invested $10 billion in OpenAI behind ChatGPT , and Google has recently released its own BARD model). Internet technology companies represented by Baidu in China have also […]

Most people are familiar with the terms circuit board, PC board and PCB. In fact, these three terms refer to the same thing. However, if you are not a friend in the electronics industry, the term PCBA may be a little strange and may be confused with PCB. Although PCB and PCBA are only one […]
What is UL? Underwriters Laboratories (UL), founded in the United States about 120 years ago, is an independent facility for testing the safety of new products and technologies. Today, it has websites all over the world and focuses on product safety. It tests products, certifies manufacturers, and produces and updates safety standards for a wide […]
PCBA chip processing factory improves PCBA welding method 1、 Improve welding temperature and time The intermetallic bond between copper and tin forms grains, and the shape and size of the grains depend on the duration and strength of the temperature during welding. Less heat during welding can form fine crystalline structure and form excellent welding […]
Semi-curable sheet is a major category of products sold as commodities in the PCB FR-4 copper clad plate industry. When making multilayer printed boards, PCB factories use it to bond the prepared inner boards. Previously, the production of multilayer printed circuit boards required at least two semi-cured sheets for each layer, so that the resin […]
The copper plating quality of printed circuit board is closely related to the application reliability of printed circuit board. With the development of printed boards to high density and high precision, the requirements for copper plating are also higher and higher. It is not only required that the coating is uniform and fine, but also […]
When designing HDI circuit boards, we should first follow IPC guidelines and standards. Four are specifically applicable to HDI circuit board design, as shown in Figure 1. IPC/JPCA-2315: This is an overview of HDI and provides a model for estimating the design density. IPC-2226: This specification educates users on micropore formation, wiring density selection, design […]
In SMT chip processing and production, it is often necessary to take electrostatic protection measures for the assembly of electronic products to reduce the damage to electronic products. The specific methods of electrostatic protection are: (1) Reduce product friction In the rotating device of the production line, it is necessary to reduce the slipping of […]
