ABSTRACT:
A lead (12) of an electrical component (10) is formed with an arrowhead-shaped tip (20) that functions to mechanically fasten the lead and component to a substrate (14), such as a flexible printed circuit (11). The tip is formed with barbs (21) extending rearwardly from the end (22) of the tip and having a width (W) across the barbs greater than the diameter (d) of a mounting hole (13) in the substrate. With this arrangement, the barbed tips may be inserted into and through the hole, with the barbs being compressed relatively inward with respect to the hole as the tip passes through the hole, so as to fasten the tips to the substrate in preparation for a soldering operation, in which the tips are soldered (30) to conductive pad areas (16) deposited on the surface of the substrate adjacent to the tips.
