thermosetting thick-film resistor paste and its manufacturing method and the thick-film resistor

摘要

A thermosetting paste for thick film resistor, manufacturing method thereof, and thick film resistor are provided to maintain high electric conductance by using filler having negative temperature coefficient of resistance or low coefficient of thermal expansion along with carbon black. A manufacturing method of thermosetting paste for thick film resistor comprises the following steps: a step for preparing for an organic resin(S210); a step for first-mixing the organic resin(S220); a step for second-mixing the organic resin(S230); and a step for performing three roll milling about the organic resin(S240). A carbon black is injected into a first-mixed organic resin. A deaeration and filtering processes are performed about a second-mixed organic resin.
