What materials need to be prepared before PCB layout design?

In the appearance quality control of circuit board solder mask, the color of solder mask is a more important control point. For a production board using the same type of solder mask ink, the board surface solder mask has obvious color difference, which is generally not accepted by customers. So wh

The circuit board design and production process has as many as 20 processes. Poor tinning is really a headache. Poor tin on the circuit board may cause such as circuit sand holes, chipping, circuit dog teeth, open circuit, and circuit sand holes. Wire; if the hole is too thin, there will be no coppe

Circuit board brief For designers who are beginners to circuit boards, only after fully understanding the production process of circuit boards can they design circuit boards better. Therefore, it is necessary to have a certain understanding of circuit board production. The simple production process
