We are investigating alternatives to HASL finishes for more dense PWBs. OSP is not a good choice because of low solid flux and possibly long shelf life. Immersion gold is expensive and so far has been more difficult to wave solder. Has anyone had experience with a "White Tin" process? What material is "white tin". Can it be used interchangeably with HASL PWBs? Any help would be appreciated.
