Could you share test data regarding solderability on each condition with me. From our beaker test Omikron White Tin showed better result than Dexter's. And what about cost factor ? As far as I know, if HASL has 1X, 0.6 X for OSP, 1.4 X for Tin and 4.0 X for Immersion Gold. There is a tendency towarding Immersion Gold, but in the standpoint of PCB shop too much burden because most our customer want us kept same price as HASL's. In that case we have to loose our profit at least $1.0/board ( $ 10/ sq. meter).So White Tin seems to me very attractive.
