Abstract
A precision resistor of the type formed by defining a resistive path in a thin foil of resistance material attached to a substrate. Metallic interface layers are deposited on terminal pads between which the resistive path extends, so that when solder-coated copper leads are spot-welded to the terminal pads, the junction between the copper leads and the terminal pads is both a spot-weld and a solder connection.
