The main factor that determines the quality and positioning of a board is the surface treatment process. For example, OSP can spray tin, gilt and sink gold. Relatively speaking, the metal is facing the high-end board. Sunken gold due to good quality, relative to the cost is relatively high. So many customers choose the most commonly used tin spraying process. Spray tin is divided into lead spray tin (that is, hot air leveling) and lead-free spray tin. The following is a look at the differences between each process;
