PROCESS FOR MAKING ELECTRICALLY CONDUCTIVE PATTERNS

摘要

A process for making an electrically conductive pattern on a substrate including forming a patterned adhesive layer on the substrate, applying a conductive metal powder to the adhesive layer, and in a second coating pass, applying a powder containing supplementary elements to the pattern. The patterned substrate is fired to volatilize theadhesive layer and sinter the powders. This process can be used to make printed circuits on ceramic substrates which are useful in hybrid circuits, for example.
