8 layers thick gold PCB circuit board

PCB gold plating is simply the process of depositing gold onto the surface of the circuit board by electroplating. SMT placement has always been difficult as ICs and IC pins have become denser. Electroplating is an important stage in PCB production. Different types of materials such as copper, nickel, tin and gold. However, the gold-plated circuit boards stand out. Because of its conductive properties, gold can be used to plate circuit boards.

Besides electrical conductivity, gold has other properties. These make it ideal for PCB plating. Experts use gold contacts on PCBs with membrane switches. Since gold plating has strong adhesion, you can attach gold particles to the PCB. Gold plating is a surface treatment method that uses electrochemical electroplating to deposit gold onto another metal.
