To all those subscibers I've misled, I made the statement "...Entek doesn't work on flex..." This was a misleading statement and I'd like to clarify myself. The flex manufacture I was working for wanted very much to approve an annti-ox coating for a very large OEM. The problem encounterd was that this program had stiffeners and/or heat sinks on the parts. These heatsinks/stiffeners created hot spots in the IR reflow which can cook off the coating. It was for this reason that I made the above statement. I meant in no way to discourage the use of such coatings on flex, but only to be careful. As a former engineer in the flex industry, I'm a big proponent of flex circuity, and should be more care about throwing statements out onto this forum without more clarification. Again I apologize, [log in to unmask] ps. Though I've learned my lesson, I'll give my address for further chewing-out.
