To summarize, the production process of a typical pcb factory is as follows: blanking → inner fabrication → pressing → drilling → copper plating → outer fabrication → soldering paint printing → text printing → surface treatment → contour processing.
Image of local separation caused by local expansion between layers of substrate or between substrate and conductive foil or between substrate and protective coating.
To form the pad, the solder shield (insulating layer) forming process is required, as well as to protect the copper foil and provide better insulation.
In electronic assembly, printed circuit board is a key component. It is equipped with other electronic parts and connected to the circuit to provide a stable circuit working environment.
This article will effectively take you through the stages of the printed circuit board design process, but will focus more on the etching and stripping process of the board.
If the design rules do not meet the requirements of PCB manufacturing process, it will not only affect the function of the product so simple, even can not process can not realize the design intention of the engineer.
Before PCBS, circuits were made up of point-to-point wiring. The reliability of this method is very low, because as the circuit ages, the rupture of the line will cause the line node to break or short.
