Planning PCB to reduce interference, just do these things
Anti-interference is a very important link in modern circuit design, which directly reflects the performance and reliability of the entire system. For PCB engineers, anti-interference design is the key and difficult point that everyone must master. The presence of interference in the PCB board In...Read more -
How to understand the circuit board circuit diagram
How to understand the circuit board wiring diagram? First of all, let’s first understand the characteristics of the application circuit diagram: ① Most of the application circuits do not draw the internal circuit block diagram, which is not good for the recognition of the diagram, especiall...Read more -
Why should PCB be immersed in gold?
1. What is Immersion Gold? To put it simply, immersion gold is the use of chemical deposition to produce a metal coating on the surface of the circuit board through a chemical oxidation-reduction reaction. 2. Why do we need to immersion gold? The copper on the circuit board is mainly red c...Read more -

Talking about the advantages and disadvantages of FPC circuit boards
We usually talk about PCB, so what is FPC? The Chinese name of FPC is also called flexible circuit board, also called soft board. It is made of soft and insulating materials. The printed circuit board we need belongs to pcb. One kind, and it has some advantages that many rigid circuit boards do n...Read more -
Analysis of related questions about the color of pcb circuit boards
Most of the circuit boards we use are green? Why is that? In fact, PCB circuit boards are not necessarily green. It depends on what color the designer wants to make it. Under normal circumstances, we choose green, because green is less irritating to the eyes, and the production and maintenance pe...Read more -
