FAQ

1. Q: What is Si gold plating?
​A: Si gold plating, that is, silicon gold plating, is a technology for gold plating on the surface of silicon materials. This technology can enhance the electrical conductivity, corrosion resistance and aesthetics of silicon materials, while also helping to improve the performance of silicon materials in some specific applications.

2.Q: What is the process of Si gold plating?
A: The process of Si gold plating usually includes three steps: pre-treatment, gold plating and post-treatment. Pretreatment is mainly to clean the surface of the silicon wafer to remove impurities such as oil and oxide; Gold plating is to deposit a layer of metal gold on the surface of the silicon wafer by electroplating, electroless plating, etc. The post-treatment is to cure and polish the gold-plated layer to improve its adhesion and aesthetics.
