Abstract
A system of single lead clamping and bonding in the assembly of integrated circuit devices. A capillary bonder has a clamp member rotatably mounted around the capillary for movement with the bond head. The clamp is moveable vertically to contact and clamp a terminal to be bonded. The clamp is rotatable to orient itself with respect to the terminal and the fine wire. The capillary and clamp move under computer control to make a series of bonds, typically between lead frame fingers and terminals on a semiconductor device.
