The bonded joints of aluminum, copper and test sheets coated with silver and gold respectively were tested, using seven kinds of the conductive adhesives with different compounds under five different environmental conditions. The bond strength remained unchanged after high temperature and UV test, but the joints deteriorated faster in high humidity and especially under the water-immersion test. The bonded joints of test pieces coated with silver and gold respectively were not good at high temperature and high humidity, and consequently their resistivities somewhat increased, in the case of aluminum joint the resistivity increased more. When a coupling agent was properly added, the bond strength increased.

The measurement data and theoretical analysis are given in this paper.
