The obtained Ag—Pd alloy solution is drawn to obtain a Ag—Pd alloy wire. The Ag—Pd alloy wire is then drawn to obtain a Ag—Pd alloy bonding wire with a predetermined diameter. | 09-23-2010 |
| 20100239456 | COMPOSITE ALLOY BONDING WIRE AND MANUFACTURING METHOD THEREOF - A manufacturing method for a composite alloy bonding wire and products thereof. A primary material of Au and Ag is melted in a vacuum melting furnace, and then a secondary metal material of Pd is added into the vacuum melting furnace and is co-melted with the primary material to obtain a Au—Ag—Pd alloy solution. The obtained Au—Ag—Pd alloy solution is drawn to obtain a Au—Ag—Pd alloy wire. The Au—Ag—Pd alloy wire is then drawn to obtain a Au—Ag—Pd alloy bonding wire with a predetermined diameter. | 09-23-2010 |
