A welded wire termination for use in thermally and mechanically stressful environments is provided by forming a wire termination tab on a conductive pad (12) to define a tubule (20) for receiving a wire, either stranded or solid. The tubule is tweezer welded to form a welded termination joint (30) between the wire and the conductive pad. The tubule easily captures all of the stranded wires and increases the surface area of the weld to a solid lead. A tweezer weld exerts pressure laterally on the tubule, and thus does not exert a force on the underlying substrate (24) that could damage the substrate. This approach creates only a single electro-mechanical connection from the wire to the conductive pad, which is inherently more reliable than multiple connections such as those that are crimped first then welded. <IMAGE> |
