Abstract
A pad is adjacent a hole that will be located on the trailing edge of the board when the board is processed through wave soldering. The pad includes a curved side that faces the hole. In addition, corners are absent from the pad. The intersections of sides of the pad occurs as a curve or radiused corner, rather than a verticed corner. Wave soldering the printed circuit board with the pad greatly reduces bridging of a lead inserted into the hole adjacent the pad.
