Abstract
PURPOSE:To obtain a high quality junction wire by coating a high purity Ag wire with high purity Au or alloys adding Be, Ca, Co, Fe, Ge, Ni or one group of Pd, Pt, Rb, Ir, Os, Ru or elements out of both groups to Au. CONSTITUTION:Ag and Au of 99.99W/O or more are easily alloyed and have good break strength and metallic wires composing of the above Ag and Au will not peel off at the time of junction. The sulfuration of Ag will also be prevented by Au coating. If the gross amount, about 0.0003-0.01W/O, out of Be, Ca, Co, Fe, Ni is added to Au, mechanical strength will further be increased. The amount of 0.0003-0.01W/O, or less will have no effect and that of 0.01W/O or more will have inferior junction. Pd, Pt, Rh, Ir, Os, Ru also adapt well themselves to Au or Ag. Therefore, 0.0003-0.1W/O in gross amount out of them may be added to Au or Ag to increase the mechanical strength. The amount of 0.0003W/O or less will have no effect and the slip of wire is not good for the amount of 0.1W/O or more. When addition is made from both groups, about 0.0003-0.11W/O in total amount will be suitable.
