Immersion Tin PCB Printed Circuit Board Manufacturing

2021-10-25  Chemical immersion tin is a PCB copper surface treatment technology. The products of this process will neither contaminate the solder (unlike chemical nickel-gold board) nor produce an additional polyester layer on the solder mask. The method can be evenly covered with a layer of tin in any size PCB hole and the position of the connection plate.
