Wedge bonding utilizes a wedge tool to form the stitches on both ends, without the use of a ball for the first bond. The bonds themselves a thin and wedge-shaped. Wedge bonding can utilize both gold and aluminum wire but is more commonly aluminum wire at ambient temperature. The wedge bonding process uses both ribbon or round wire for bonding. Unlike the capillary found on a ball bonder, the wedge bonding tool needs to be oriented in the direction of the bond and as a result, can rotate to bond from all angles. This allows for bonding from any and all angles for a given assembly.
