Copper Conductive Paste and Resistive Paste for External Electrodes of Resistor
PRODUCT DESCRIPTION
Instead of using precious metal like traditional resistor, it use copper as conductive material and copper-nickel as resistive material, and it’s designed to replace low-resistance precious metal paste. Presently it can apply to components whose resistance is between 0.1 to 5 Ω, while the appearance after plating shows no difference to traditional type.
MAIN FEATURE
-
Printing paste.
-
Sinter under nitrogen atmosphere, sintering temperature is 900+/-20℃.
-
The conductive part is copper paste, and the resistive part is copper-nickel paste.
-
Good adhesion between paste and substrate after sintering.
