Reel to Reel Solderability


Soderability Problem on Reel to Reel

I need information on troubleshooting solderability problems related to tin plating. We are having difficulty passing a solderability test. We are plating s/s with a ni strike, sulfamate ni followed by tin. We are experiencing de-wetting.

Please advize if there is any info. about this problem available.

The sulfamate bath should be squeaky clean (carbon treat), and what kind of tin bath are you using? Organic contamination will cause de-wetting.

Regarding solderability fail, I recommend the followings:

- In case of thin tin thickness by wide thickness distribution and average low thickness,elevate to Min. 250 microinches in thickness.

- In case of organic contamination in the tin bath, check the level regularly:deposit tin on bright dipped sus,dry and peel it off carefully and then measure the carbon level with the carbon analyzer.

- In case of inorganic contamination,copper/nickel,check the metallic impurities by AA unit.

- In case of poor pre-treatment, check the solution and process stages,drag-in?/nickel surface after nickel plating?....

- MSA based plating chemical is recommended.
