Thanks LD! I'll Take that to the shop. I've been burnt by "violet" one to many times. Not to say that any of us are willing to use violet in a descriptive sence. I can't believe she is still out there. "Big Venture" much better! Did you get that off

I would suggest that as well as repeatedly inspecting the same board and looking at the standard deviations of the measurements, you should perform some form of accuracy test either by measuring a known glass plate or by inspecting a board at 0 and 1

Thanks for your feedback. I definitely agree with your viewpoints. Can you send across any documents/papers through e-mail or post them on the smtnet which clearly describes the HARMFUL EFFECTS OF WHITE RESIDUES. My customer's only apprehension is
