Abstract

A precision resistor has a thin resistive foil 12 cemented to a much thicker rigid substrate. The foil has formed therein a pattern defining the resistive path between terminal pads 14. Copper leads can be spot-welded directly to these pads without damage to the junction between lead and pad. To that end, apertures 25 are provided through the terminal pads, through which cement softened by the spot-welding heat can locally expand and gas evolved under pressure can escape, all without adversely affecting the junction and without substantial lifting of the terminal pads from the substrate. <IMAGE>
