To remove and replace usually means the go back through the cleaning portion with possibly the same result. Does not make sense to do that. Ever since CFC went away we been using cleaning solvents, high pressure wash, etc and component manufactures marking can not always with stand the aggressive cleaning. We use to put varnish on IC to protect marking years and years ago. Might look at IPC Test Methods and see if anything is in there about receiving inspection having to test component markings like the old MIL-STD-208 series did. Component spec hopefully can tell you the type of ink or marking used and maybe that will lead to solvent compatibility issue or non issue. Just thoughts, Jon -----Original Message----- From: Ken Bloomquist [mailto:[log in to unmask]] Sent: Monday, August 14, 2000 12:43 PM To: [log in to unmask] Subject: [TN] Component Markings Good Day Technetters, I have searched the archives and couldn't find the answer to my question. J-Std-001, 9.2.2, says that you can not deliberately alter, obliterate or remove component markings. It goes on to say that random part marking loss...... does not constitute deliberate obliteration. This doesn't say if the later condition is OK. We have one faction here that believes components need to have markings no matter what. They want us to re-mark or remove and replace any components that have had their markings degraded, due to the cleaning processes after soldering. I contend that we are doing more damage by removing and replacing these components than just leaving them alone. These Class 3 assemblies are tested and have traceability to the component level. Replace, Re-mark or Leave Them Alone, that is the question! Any information that could help load my cannons would be appreciated. Thanks in advance for your responses.
