ABSTRACT:
A fabricating method and apparatus of an zinc phosphate coating for a varistor has a insulation formed on a surface of a body which does not include two opposite ends of the body formed two outer terminals. The insulation has anti-etch feature for the electrolyte, so that the exposed surface of the body prevents to be etched and to be electroplated a metal material on it. Therefore the varistor has a great fabricating yield and the great shape after electroplating the two outer terminals step.
