Comparison of copper and silver thick film on alumina substrates properties

This paper deals with comparison of copper (Thick Printed Copper) and silver thick films on alumina substrates properties. Thick film technology is used in many fields of electronic industry. Thick printed copper is a new prospective technology, which is used for power electronics substrate manufacturing. Comparison of adhesion, solderability and other properties of TPC technology and silver thick films are mentioned in this paper.
