Abstract
PURPOSE:To obtain an excellent bonding wire by limiting the purity of Pd by weight to more than 99.97%. CONSTITUTION:When the purity of Pd of less than 99.97wt%, Cu, Fe, Mg, Si, Al, Ca, B, Cr, Zn, Sn, Pb and so forth readily oxidizable in the Pd and their oxides obstruct the preferred properties of the Pd in general and hence deteriorate the bonding property of the Pd. When this purity is thus limited, its fracture strength can be particularly improved, and excellent rate of elongation and excellent bonding property can be exhibited.
