PCB (Printed Circuit Board), the Chinese name is printed circuit board, abbreviated as printed circuit board, is one of the important components of the electronics industry. Almost every electronic device

What should be paid attention to in the anti-corrosion treatment of multilayer circuit boards

Before designing multi-layer PCB, the designer needs to first determine the circuit board structure according to the scale of the circuit

Our common computer boards and cards are basically epoxy resin glass cloth based double-sided printed circuit boards. One side is the plug-in components, and the other side is the welding surface of the component feet. It can be seen that the welding points are very regular

According to the number of layers, there are three types of single-sided, double-sided, and multi-layer circuit boards, which are distinguished according to the circuit layers inside.

Printed circuit board (PCB) is a substrate for assembling electronic parts. It is a printed board that forms the connection between points and printed components on the general substrate according to the predetermined design. According to different classification methods
