PURPOSE:To enhance the mechanical strength of gold wire by containing the first element group of Ag, Ge, Ca, Fe, Mg, the second element group of Ti, Cu, Si, Sn, Bi, Mn, Pb, Ni, Cr and so forth and the third element group of other metals in Au. CONSTITUTION:The first element group of Ag, Ge, Ca, Fe, Mg, the second element group of Ti, Cu, Si, Sn, Bi, Mn, Pb, Ni, Cr, Co, Al, Pd, and the third element group of other metals are contained in a highly pure Au. The Ag of the first group is contained 2-80ppm, Ge is 5-80ppm, Ca is 1-20ppm, Fe is 0.5-10ppm, Mg is 0.5-30ppm in the ranges. Thus, the mechanical strength of the bonding gold metal can be enhanced, thereby increasing the strength after bonding. |
