Abstract
This application provides a graphene-bonded silver alloy wire and its preparation process, belonging to the field of bonding wire technology for packaging. The preparation process of this graphene-bonded silver alloy wire comprises the following components by weight percentage: graphene content 1000-4500 ppm; Pd content 10000-20000 ppm; the balance being Ag and impurities. With the addition of low gold and palladium content, the graphene-bonded silver alloy wire effectively improves the susceptibility of bonded silver alloy wire to moisture and sulfur / chlorine corrosion, thus migrating silver ions. It achieves the corrosion resistance and silver ion migration inhibition effects of traditional bonded silver alloy wires, significantly reducing material costs and possessing significant scientific research value and application prospects. Furthermore, the circular limiting ring seat, positioning groove, and conical pressure block of the high-tension wire drawing machine in the preparation process enable the high-tension wire drawing machine to quickly fix the I-beam and the wire, greatly improving production efficiency.
