Abstract
Substantially flat thin foil electrical components, e.g. thin foil resistors, are disclosed wherein a thin metallic foil is bonded to an insulating substrate and a circuit path is formed on the foil by photographic artwork-etching or other techniques. Terminal lands of the circuit are electroplated on the foil connecting leads having paddles or flattened portions formed with a hole or slot therein are soldered to the lands such that the solder extends into the hole or slot. The value of the resistor is finally adjusted by use of a laser beam, at least one bead of rubber is applied on at least a portion of the edges of the substrates, and the resistor is encapsulated.
