Electrodeposited (ED) or electrophoretic polymer coatings are useful as dielectric sealants for anodized aluminum printed wiring boards using polymer thick film (PTF) pastes for conductor lines. As a means of increasing density of circuit lines and also conductivity of circuit lines, it is desirable to plate the electrodeposited coating. After the plating, photoimaging, and etching steps, a circuitized printed wiring board can be produced.
