In the production of electronic products, there will be a production process of printed circuit board. Printed circuit boards are used in electronic products in all industries. It is the carrier of electronic schematic diagram that can realize the design function and turn the design into physical products
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
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.
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
Before designing multi-layer PCB, the designer needs to first determine the circuit board structure according to the scale of the circuit
What should be paid attention to in the anti-corrosion treatment of multilayer circuit boards
