TechNetters, I'm following up on a discussion we had some months back, regarding use of an Omegameter at the end of a cleaning operation for SPC. Our production manager asked if we could use a single, standard board, run it through the solder wave and cleaner, then test it in the omegameter, doing this at prescribed time intervals for SPC. Let me make sure I'm clear: this standard board would be one unit, that would be used repeatedly to check the cleaning operation. Using the single, standard board would eliminate variablity from handling, board and material composition, and all the things that affect the omegameter reading. The only variables (we speculate) would be in the solder wave and the cleaner, the latter of which we are wanting to control. What, if anything, is wrong with this idea? My understanding is that incompletely cured laminate can release ionic material. Could there be any such problem with solder resist?
