摘要
A thick film conductor material comprising metal particles containing both gold and at least one additional element prealloyed into a single particle. The additional element may preferably be Pd and the prealloying may preferably be accomplished by coprecipitation. The conductor material, when bonded with Al wire, impedes the growth of intermetallic compounds and subsequent Kirkendall voids, even at elevated temperatures.
