Abstract
A method is provided for electrically interconnecting a plurality of varistors of the type formed predominantly of metal oxide. Molten solder is first applied to the receiving surfaces provided on opposite sides of each of the varistors. The molten solder is then subjected to vibrations of from 5,000 to 35,000 hertz, causing the solder to strongly adhere to the receiving surfaces. The varistor bodies are then soldered to one another along their receiving surfaces to electrically interconnect the varistor bodies. In one embodiment of the method, the applying of molten solder, vibrating the molten solder, and soldering the varistor bodies to one another are all performed substantially simultaneously by means of a vibrating solder bath.
