Patent ID: 8590140

Claim:
A fabrication method of an alloy resistor, comprising the steps of: providing an alloy sheet having a plurality of openings spacing apart from each other and going through the alloy sheet and a plurality of alloy resistor units located between any two adjacent openings, wherein each of the alloy resistor units has an insulating cover area and a plurality of electrode ends on both sides of the insulating cover area; forming an insulating layer on a surface of the insulating cover area of the alloy resistor units by an electrodepositing coating process, wherein the formation of the insulating layer comprises the steps of: forming a deposition resistant layer on a surface of the alloy sheet for exposing the insulating cover area of the alloy resistor units; forming the insulating layer by the electrodepositing coating process; and removing the deposition resistant layer; cutting the alloy sheet to obtain a plurality of separated alloy resistor units; and forming a conductive adhesion material on the electrode ends of the alloy resistor units.
