What is the role of Shen Jin and Jin Jin in PCB board?

First of all, let's first introduce what is Shen Jin? The copper on the circuit board is mainly copper. The brazing joints are easily oxidized in the air. This causes electrical conductivity, that is, poor tin or poor contact, which reduces the performance of the board. Therefore, the brazing points need to be surface treated. [...]
