Product Details

PCB Knowledge:

Immersion Tin is a new surface treatment process, and it has many similar characteristics with silver immersion process. However, since thiourea (which may be a carcinogen) used in the Immersion Tin process during PCB manufacturing which needs to be prevented, there are significant health and safety issues to be considered. In addition, it should pay attention to the tin migration ("tin burr" effect),although anti-migration chemicals can have some effect in controlling this problem.  

 

Advantages: good solderability, flat surface, relatively low cost.

Disadvantages: health and safety problems, number of thermal cycle is limited.(pwb board)
