20130171470 | ALLOY WIRE AND METHODS FOR MANUFACTURING THE SAME - An alloy wire made of a material selected from one of a group consisting of a silver-gold alloy, a silver-palladium alloy and a silver-gold-palladium alloy is provided. The alloy wire is with a polycrystalline structure of a face-centered cubic lattice and includes a plurality of grains. A central part of the alloy wire includes slender grains or equi-axial grains, and the other parts of the alloy wire consist of equi-axial grains. A quantity of the grains having annealing twins was 20 percent or more of the total quantity of the grains of the alloy wire. | 07-04-2013 |
20130233593 | COMPOSITE WIRE OF SILVER-PALLADIUM ALLOY COATED WITH METALLIC THIN FILM AND METHOD THEREOF - The invention provides a composite wire for electronic package, the composite wire including an alloy core member and a plating layer forming on a surface of the alloy core member. The alloy core member is silver-palladium alloy. The plating layer is at least one layer of thin film of pure gold, pure palladium or gold-palladium alloy. The invention also provides a method for manufacturing the composite wire. The method includes steps of: (a) providing a wire rod, (b) forming a wire having a predetermined diameter from the wire rod by a plurality of processes including cold working and annealing and (c) forming a plating layer on a surface of the wire rod before step (b) or forming a plating layer on a surface of the wire after step (b) by electroplating, sputtering or vacuum evaporation. | 09-12-2013 |
