A flatwire assembly includes a pair of elongate flatwire segments that are interconnected with a thin, flexible patch that overlies the opposed longitudinal ends of the segments. Conductive traces on the bottom face of the patch are electrically connected to the respective conductive traces of the segments by solder layers that, upon reflow under heat and pressure, respectively extend past an edge of the patch, whereupon visual confirmation of the solder joints between the traces of the patch and the segment is readily obtained. A layer of a thermally-activated or pressure-sensitive adhesive is disposed between the patch and each segment to further mechanically couple the patch to each segment during solder reflow. Longitudinal extensions of the patch substrate are bonded by the adhesive layer to respective portions of the segments farther removed from the segment ends than the solder layer extensions provide enhanced strain relief.
