Abstract
A printed circuit board is provided having a beveled edge for ease of insertion into a receptor. The beveled edge is extended onto the solder mask to present a contiguous beveled surface. Moreover, the PCB includes bonding pads which can be surface mounted with pins extending from the receptor. Each bonding pad includes a forward portion and a rearward portion. The forward portion is covered with the solder mask layer to present a smooth surface channeled inward in a V-shaped configuration. The forward portion channels or directs the pin along a central axis near the apex of the V-shaped forward portion onto the upper surface of the bonding pad rearward portion. Accordingly, the pin is channeled to an area absent solder paste along the central axis such that during subsequent reflow operation the solder paste is reliably extended over and around the centrally placed pin.
