Abstract

PURPOSE:To improve the processing capacity of a wire bonding work by providing a plurality of bonding head mechanisms. CONSTITUTION:At least two bonding head means 2, 2' for wire bonding a pellet to a lead frame are provided. The bonding head mechanism 2 bonds every other pellets on a lead frame 5, and the bonding head mechanism 2' bonds all the remaining pellets. Thus, the throughput capacity of a wire bonding apparatus is improved twice with respect to one bonding head mechanism. The load of the wire bonding region to the mechanisms 2, 2' is assigned by dividing one pellet as designated by reference characters A and B.

Normally, in the manufacturing process of semiconductor devices, there is a mounting process in which a pellet is mounted on a lead frame before the wire bonding process of connecting the pellet on the lead frame and the lead frame. The wire bonding process for connecting wires at multiple locations requires three to four times as much time.

Therefore, in the above-described bonding apparatus, since there is only one bonding head, only one pellet can be bonded at a time, leading to a decrease in productivity.
