ABSTRACT:
Extremely thin polymer film substrates are conditioned for subsequent electroless plating by contact with a mild caustic solution. Aqueous solutions of about 1/2 wt % NaOH or KOH can successfully condition polyimide films with contact times of less than an hour. The more robust PET polymer films benefit from the addition of a permanganate salt to the solution to accelerate the conditioning process. Since these films are so thin, less than 1 mil, significant loss of polymer is not necessarily desirable. This process is designed to roughen the surface of the polymer film and render it hydrophilic to enhance the effectiveness of the subsequent electroless metal film deposition.
