Comparison of copper wire connections and gold wire connections:

1. Copper wire that has undergone annealing treatment is about 33% harder than gold wire, so the pressure and stress on the pad during copper wire bonding are much higher than those during gold wire bonding. The resulting pad damage and damage to the underlying structure can sometimes be difficult to control.

2. Compared with gold wire connections, copper wire connections mainly have the advantages of lower cost and better electrical performance. Copper wire connections are a very good solution, as they can avoid the increased costs associated with using flip-chip applications, and at the same time, copper wire has 23% higher conductivity than gold wire of the same diameter.
