ABSTRACT:
A printed circuit board (10) comprises a polymeric coating (30) and a metal circuit trace (26) applied to a substrate (22). The coating defines an opening (32) whereat the substrate is uncoated. The metal circuit trace includes a runner section (28) that is covered by the polymeric coating and a bond pad (20) integrally formed to the runner section at the opening and having an upper surface (40) that includes lip (36) overlying the polymer coating to facilitate positioning of a component for solder bonding to the pad. The bond pad preferably also includes a surface accessible within the opening to enhance solder bonding to the bond pad.
