Why is it necessary to add a coating on the PCB board during SMT processing in Yantai

I don't know if my friends have noticed a problem. Nowadays, many SMT processing manufacturers in Yantai will specifically mention that their products use special processes such as gold plating and silver plating when promoting their products. By now, many friends will probably think that this process will be helpful for the use of the products. So today, let me give you a detailed summary and sharing.

In fact, industry insiders should be aware that various components need to be welded on the surface of sheet metal, but it requires a portion of the copper layer to be exposed for welding. The problem is that over time, copper is easily oxidized, leading to difficulties in welding later on and increasing resistance, which affects the performance of the product. So engineers came up with various ways to protect the solder pads, and gold plating and silver plating are one of them.

From this perspective, whether it is gold or silver, the purpose of the process itself is to prevent oxidation, protect the solder pads, and ensure yield in the subsequent soldering process.
