If this component is laser marked, you could just spray conformal coat on it and the marking will disappear.

What type of conformal coating spray ? Is it permenant or washable ?

You don't mention any particular IC or manufacturer or marking method. However, most IC marking is done with lasers these days. The laser actually alters the encapsulation so the only way to erase the marking is to remove the encapsulation. Otherwise

Prior to packing the boards, we cover the marking on the IC by dispensing epoxy on top it. This is a way to protect our design so no one can copy it. We have a lot of boards and the optr takes a long time doing it manually. im thinking of using a pne

Any ol' acrylic or urethane will work. It's possible to remove these conformal coatings. We've never removed coating from components to determine if the marking is still unlegible

John: As one of the previous replies indicated a LASER of the proper wavelength (organic materials) will do this job. Contact BEST at http://www.solder.net offline to see if this is an option you want to pursue. Other methods include labels and m

I agree, except you need to be careful with the depth of cut since it may affect the package internal connections (wirebonds) -A
