The use of silver and silver plus gold conductors with the ferro low temperature tape

Abstract

For low temperature co-firable ceramic tape to play a significant role in the replacement of both alumina for high temperature packaging and conventional thick film hybrid materials on alumina it is essential that a full range of stable conductors, resistor and capacitor materials be available that are compatible with the LTCC during the firing process. The FERROTAPE A6 system provides for the first time such a range of materials to complement the unique properties of the tape, (low microwave insertion loss, K=5.9 and compatibility with silver conductors). The tape can be used with either silver or gold conductors and a technological breakthrough now allows both silver and gold to be used together as a result of the development of a novel via material. This paper presents information on the complete range of FERROTAPE A6 materials.<>
