Abstract
The present invention provides a novel method of reducing the amount of seed deposited on polymeric dielectric surfaces. The method comprises the following steps: providing a work-piece coated with a polymeric dielectric layer; baking the work-piece to modify the surface of the polymeric dielectric layer; then applying the seed to polymeric dielectric layer and electrolessly plating metal to the seed layer. The invention also relates to a circuit board produced by the method of the present invention.
