I need to clean some metallic mating surfaces and since I have to use this same equipment in the future, I don’t want to just lightly sand the surfaces if I can help it. I suppose like gold contact I might be able to use the old eraser trick but I would like to chemically clean the surfaces to remove any coating contamination or oxidation without taking off the coating or the underlying metal plating – any body got a favorite cleaner?
I have a support PC made by one of the biggie manufacturers that I desperately need to meet class B emissions because it is the only one I have to drive the test item. Unfortunately it has what I’m sure the Mechanical Engineer thinks is a robust solution for the I/O panel for user added cards. From a brand new one time user perspective it is pretty slick, no tools need, just snap a couple of plastic fulcrums to different position to remove or add a card. The card face mates into a very delicate little lace interface of punched tin plated “?” gasket that conforms at several points along the I/O card face panel and the inside of the computer housing. The fit happens exactly once as far as I can tell. It mostly crushes and distorts and just leaves a cap running between the I/O card faceplate and the computer chassis. I’ll give them style points – but I’m going to whack somebody over the head for the execution.
