Craig,

How about a spray process? If you keep the epoxy coating thin, you might not be as concerned about overspray, so confining the application isn't as big a problem.

Or if you are looking for a different method, maybe laser? (depends  on the component material?)

Subject: EXTERNAL: [TN] Obscure IC part markings

I have a customer requirement to "apply an electronics grade epoxy over component x that will obscure part the part marking." They are trying to prevent reverse engineering of their product. There are of course a multitude of epoxies, but dispensing onto small ICs, etc., can be a challenge. 

 

I know about micro abrasion processes and such but I'm curious how others would handle this requirement?
