ImAg Boards? -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Leland Woodall Sent: Friday, 15 October 2010 3:49 AM To: [log in to unmask] Subject: [TN] Detecting Oxidation Levels of PTH Techies, We have one assembly that sporadically experiences insufficient solder fill of plated through holes at the wave soldering process. If we cross section one of these, what testing equipment is best suited to detect the presence of oxidation on the PTH walls? What would be considered an unacceptable level that would prevent 100% climb? Thanks in advance for your responses!
