The immersion white tin we have seen requested is Omikron by Florida CirTech
and I have heard of Dexter and Alphametal producing an immersion white tin.
Supposedly assemblers are moving to the IWT because it is more reworkable
than OSP, the surface co-planarity is good and so is the solderability.
We're trying to determine where the industry is going, is anyone else seeing
this happen?
