Embodiment Construction
[0009] The composite silver wire of the present invention contains gold, palladium, platinum, and other components such as silver.
[0010] Wherein, the weight percentage of gold is greater than or equal to 4wt% and less than 8wt%. If the gold content is lower than 4wt%, the hardness of the alloy of the present invention will be too high, which will easily lead to poor workability. If the gold content exceeds 8wt%, The workability and reliability of the composite silver wire of the present invention not only fail to be significantly improved, but also greatly increase the cost.
[0011] The weight percentage of palladium is between 2wt% and 4wt%. If the palladium content is lower than 2wt%, the composite silver wire of the present invention cannot pass the high temperature and high humidity reliability test. If the palladium content is higher than 4wt%, the composite silver wire of the present invention cannot Alloy hardness of the composite silver wire is too high, resulting ...
