A conductor pad, formable on a substrate or a printed circuit board, for conducing the reduction of gas voids in solder when an electronic device is soldered to the conductor pad, wherein the conductor pad includes a uniform and electrically conductive base layer having an interface surface, and also includes a patterned layer formed on the interface surface of the base layer, wherein one of the base layer and the patterned layer is substantially non-wettable and the other is substantially wettable, and wherein the base layer and the patterned layer cooperatively define strips of non-wettable surface areas which extend across the interface surface of the base layer. The strips of non-wettable surface areas can be defined upon the interface surface of the base layer in various ways to thereby create various non-wettable patterns upon the base layer. Preferably, the base layer is substantially wettable, and the patterned layer is both substantially non-wettable and electrically conductive.
