Abstract:
A surface mount semiconductor circuit device comprising:a substrate having a surface with at least one edge defining a periphery of the device;vias in the surface of the substrate, at least two of the vias being adjacent to each other and substantially equally spaced from the edge of the substrate;solderable input/output pads on the at least two vias, a first of the input/output pads being closer to the edge of the substrate than a second of the input/output pads, each of the input/output pads having an oblong shape in a direction perpendicular to the edge of the substrate; anda reflowed solder bump on each of the input/output pads, each of the reflowed solder bumps having an oblong shape congruent to the oblong shape of its corresponding input/output pad.
