First Claim
Patent Images
1. A process for applying a protective coating to a flex circuit comprising:
- providing a flex circuit having conductive traces on one surface of the flex circuit;
providing a liner having at least one opening; and
,applying a protective coating in substantially a liquid state to the one surface from a first roller including the protective coating in a pattern thereon, wherein the pattern includes at least one area on the one surface of the first roller that is not covered by the protective coating,wherein applying the protective coating comprises applying the protective coating to the liner with the first roller in the predetermined pattern and then applying the liner to the one surface of the flex circuit so that the at least one opening of the liner is aligned to create at least one opening of the protective coating on the one surface.
