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

Hi Oswald, Shelf life with ENIG if vacuum sealed and kept in controled enviroment would be 12 to 14 months. Shelf life in shrink wrap - No recomended packaging, 6 moths. If Shelf life goes over the 12 -14 months - Baking ? I would not suggest re-b
