I agree that it should not but would as Carrie suggests use markers made for this. They are available in red solvent soluble and blue water washable. -----Original Message----- From: Ronald Currell [mailto:[log in to unmask]] Sent: Wednesday, January 08, 2003 10:48 AM To: [log in to unmask] Subject: [TN] Question Re: Marking Defective Solder Joints Hi, I am setting up a QC Station between our Board Department and the Technicians, who install the PC Boards into Instruments. I would like nonconformances marked right on the solder joints with a red marker. If the ink is not removed prior to the re-work process, will the ink contaminate the Solder Joints? I suspect that the surface tension of the solder will not allow contamination to occur. What do you think? Please reply to [log in to unmask] Thanks, Ronald G.
