GAISER SMALL WIRE WEDGE INFORMATION   

20. DEEP ACCESS STANDARD SHANK DESIGNS PAGE 1 (2)

The deep access wedge design was created to meet the challenge of bonding into deep cavity packages. The high walls of these packages make access with conventional 30 , 45 , and 60 wedge bonders very difficult.

With a conventional bonder, the position of the wire clamps behind the bonding wedge limits access in the deep package. Also, the wire may be impeded between the wire clamps and the wedge by these walls.

The deep access wedge bonder feeds the wire vertically down the center of the tool. The wire clamp is located above the wedge instead of behind the

wedge. This clamp position allows the wedge to penetrate deep cavity packages.

The deep access bonding wedge is a combination of both a wedge and a capillary. The wire travels through the center of the wedge shank, exits down toward the bottom, out the back of the shank, and re-enters

through the wire feed hole at either a 45 or 60 angle. This innovation in wedge bonding has provided the opportunity for small bond lengths into deep cavity packages.
