Whether the plating of the pin array bus is better than gold plating or tin plating, let's analyze which kind of plating of the pin array bus is better,
At present, there are the following coatings on the market:
1. The gilding of the row of pins and bus bars is the most common one in the market. The gilding transmission speed is fast and it is not easy to oxidize.
2. At present, tin plating on the market is cheaper than gold plating, and tin plating is also easy to tin. But it will turn yellow after a long time.
3. Half Gold Tin Plating on the pins and busbars means that the contact surface is gold-plated and the solder foot is tin plated. This plating method requires higher requirements and costs higher.
