Element e.g. conductor, resistance or di-electric prodn. on substrate - by shaping solvent free paste contg. filler and binder on substrate and hardening by microwave energy on support

摘要

Elements, e.g. conductors, resistances or dielectrics, are formed on a substrate by (a) forming the element on the substrate by means of a thick film paste contg. (i) 50-85 wt.% of a filler, and (ii) 50-15% of a binder, and free from solvent, (b) placing the substrate on a support, and (c) hardening the paste by converting microwave energy into conducted heat in the support.
