Abstract
A flattening resistor and a manufacturing method thereof are provided. The flattening resistor includes a substrate, a resistive layer, and an electrode layer. The present disclosure solves the problems of increased impedance and abnormal product characteristics caused by improper jointing of the interface between the electrode layer and the resistive layer, which includes using laser-cutting or grinding to eliminate the step difference of the interface and process the discontinuous structure of the electrode layer after the electrode layer process is completed.
Claims8
A manufacturing method of flattening resistor, comprising:
- disposing a substrate;
- forming an electrode layer on both ends of the substrate;
- forming a tangential concave platform by laser-cutting or grinding a surface of the electrode layer;
- forming a resistive layer covering the tangential concave platform of the electrode layer;
- and
- forming a protective layer on the resistive layer.
A flattening resistor, comprising:
- a substrate;
- an electrode layer disposed at both ends of the substrate, the electrode layer comprises a tangential concave platform;
- a resistive layer disposed on a surface of the substrate, wherein the resistive layer is connected to the electrode layer;
- and
- a protective layer disposed on the resistive layer and exposes the electrode layer.
