摘要: Conductive adhesive became solid at low temperature compared with Pb/Sn solder melting point. It was used as micro-interconnection material for those sensitive components. In this paper, experiments were conducted to characterize conductive joints microwave frequency. A switch attached on aluminum substrate by adhesive. The tests shear force and isolation evaluated in constant humidity 45°C 90% RH 1000h. Micro-cracks appeared the interface between a long time test. Shear decreased 2.35MPa after 100h test inclined 1.2MPa 1000h finished. Moisture went micro-cracks contact resistance of increased. Isolation rapidly first 200h steady afterwards accordance is only half beginning 6.5GHz. By contrast substrate, gold coated interconnect. 5% 6.5GHz
