Abstract

Surface-mount solder-tails (124) for use in a surface-mount edge connector (100) and other surface-mount components. The terminal members (120) are each formed with an upper-section providing a bearing surface to facilitate slidable insertion of a circuit board within connector housing (10), a mid-section which serves to anchor terminal members (120) within housing (10), and an improved solder-tail section (124) of compact design for establishing electrical contact with conductive traces on the surface of a motherboard (30). The improved solder-tails (124) are provided with an elbow to increase the length, thereby increasing the resiliency in the vertical and horizontal directions. Alternatively, solder-tails (124) may be narrowed or annealed to achieve the same result. Edge connector (100) minimizes an aggregate normal force imparted to said second circuit board (30) while maintaining a proper electrical connection, and the solder-joints are well-protected from stresses imparted to the motherboard.
