The PCB circuit board corrodes from the edge. When unpainted copper foil is corroded, the circuit board should be removed in time in case the paint falls off and corrodes the useful line. It rinses with clear water and scrapes off the paint with bamboo, etc. (the paint comes out of the liquid and is easy to remove). If it's not easy to scratch, it is just flush with hot water. Then dry, sandpaper clean, exposed shiny copper foil, a printed circuit board is done. In order to preserve the results, Rosin solution is usually coated with a polished PCB circuit board to help weld and prevent oxidation.
With the rapid development of the mobile phone, electronics, communication industry and so on, the PCB circuit board industry is growing rapidly, and people are demanding more and more layers, weight, precision, material, color, reliability and so on.
In the face of the wide variety of PCB circuit boards in the market, we can start from two aspects to distinguish the quality of PCB circuit boards. The first way is to judge from the appearance, and the other is to judge the quality specifications of the PCB boards.( prototyping board)
