ABSTRACT:
A method of manufacturing solid electrolyte chip capacitors. Each capacitor comprises a substantially rectangular capacitor element having a cathode layer surrounding it, an anode conductor rod protruding therefrom and a pair of electrode terminals disposed on the bottom face thereof. A metal strip, such as the material of electrode terminals, is punched and pressed to form pairs of L-shaped terminals with horizontal legs connected to the remainder of the strip, which face toward and spaced from each other by a distance corresponding to the full length of the capacitor element, each of the vertical legs has a pair of facing side wings separated by a distance corresponding to the width of the capacitor element. The capacitor element is inserted in each enclosure defined by the vertical legs and their wings and positioned precisely, and then encapsulated with synthetic resin. The resultant products are cut off from the strip.
