Embodiment 1
[0026] The gold alloy bonding wire of this embodiment contains 1.0% by weight of Pd, 30% of Ag, 0.5% of Cu, 1% of Pt, 80ppm of Ce, 20ppm of Ca, and the balance is gold.
[0027] In this embodiment, the manufacturing method of gold alloy bonding wire comprises the following steps:
[0028] (1) Melting and casting: Pd, Ag, Cu, Pt, Ce and Ca are added to the gold raw material in proportion, and after vacuum melting and directional continuous casting process, a wire rod with a diameter of 8 mm is obtained;
[0029] (2) Wire drawing: drawing the wire rod obtained in step (1) to obtain a bonded wire semi-finished product with a diameter of 0.5mm;
[0030] (3) Continue to draw the semi-finished bonding wire obtained in step (2) to obtain a gold alloy bonding wire with a diameter of 15-50 um (such as 20 um);
[0031] During the wire drawing process, intermediate annealing is carried out several times on the semi-finished product of the bonding wire. During the annealing process, N 2...
