Barbara, I love white tin! It is absolutely, positively my favorite finsih. The flatness, which is it's main attribute, is perfect for fine pitch, 50mil and lower, and the wetting characteristics are superb. The only downside is the thiurea (sp?). Apparently it's pretty toxic and carcinogenic. I'm sure Brian Ellis will chime in soon (I hope). Jason Gregory Production Supervisor LaBarge Inc.

Who is using this and is it working for you? What do y'all think about the "Omikron" process as opposed to other White Tin applications? Is one better than the other? Barbara J. Burcham, C.I.D.
