THICK-FILM RESISTOR FABRICATION METHOD Russian patent published in 2015 - IPC H01C17/00 

FIELD: electricity.

SUBSTANCE: in this method of fabrication of thick-film resistors which includes consecutive application by the screen printing method on the isolating substrate of conducting and resistive layers with subsequent drying and burning-in in the air atmosphere; on the resistive layer in addition a layer of high-temperature protective paste is applied using the screen printing method with the subsequent burning-in, then after laser adjustment of resistance of resistors an additional protective layer is applied using the screen printing method, then the female contacts are formed by application of low-temperature conduction paste with the subsequent drying and galvanic sedimentation of nickel and solder layers.

EFFECT: increase of output of suitable resistors with simultaneous improvement of technical characteristics of resistors.
