Abstract:
1. A manufacturing method for an alloy bonding wire, comprising: a) providing a primary material of Au and Ag; b) melting the primary material in a vacuum melting furnace, adding a secondary metal material of Pd into the vacuum melting furnace and co-melting with the primary material in the vacuum melting furnace to obtain a Au—Ag—Pd alloy, wherein the alloy excludes copper; c) casting and drawing the Au—Ag—Pd alloy to obtain a Au—Ag—Pd alloy wire; and d) drawing the Au—Ag—Pd alloy wire to obtain a Au—Ag—Pd alloy bonding wire with a predetermined diameter, wherein the weight percentage of Au in is 8.00%˜30.00%, the weight percentage of Ag is 66.00%˜90.00% and the weight percentage of Pd is 0.01%˜6.00%.
