METHOD FOR MANUFACTURING THICK-FILM ELECTRIC PART ON HYBRID CIRCUIT SUBSTRATE

摘要

PURPOSE: To form Ag/Pd conductors on a hybrid substrate. CONSTITUTION: (a) A substrate is coated with an Ag/Pd conductive paste. (b) In a burning process of the paste, oxygen is introduced to keep oxygen concentrations of 40% and more in the region, and the processed substrate is held at least for ten minutes at a temperature of 850 deg.C and more. And (c) the substrate is coated with an insulation layer, and the insulation layer is processed within the confines of the conditions described at (b).
