Abstract

Metallization of electrodeposited polymers, i.e. electrophoretic or electrocoated deposition of polymoric films, for example, acrylics provide an excellent means for applying uniform thin insulating layers on a conductive substrate, such as copper. However, adhesion problems are encountered. The described technique employs substantially identical processing steps to that previously known, but improved adhesion characteristics are realized by following the exact sequence of process steps.

Metallization Process for Electrodeposited Polymers

Metallization of electrodeposited polymers, i.e. electrophoretic or electrocoated deposition of polymoric films, for example, acrylics provide an excellent means for applying uniform thin insulating layers on a conductive substrate, such as copper. However, adhesion problems are encountered. The described technique employs substantially identical processing steps to that previously known, but improved adhesion characteristics are realized by following the exact sequence of process steps.

First, the polymer film is deposited on a conductive substrate in accordance with well-known techniques. Then the polymer film is sensitized, for example, with a mixture of stannous chloride and palladium chloride. These two steps are then immediately followed by a curing operation. The curing operation can be suitably performed with an oven baked step in the range of 350 degrees C. After the curing step, a metallizing step employing a suitable electrical metal conductor such as copper or nickel completes the operation.
