Abstract
A method and an adjustable clamp system for clamping a die assembly during wire bonding. The system includes at least one pair of opposing base walls, each of the base walls has a base clamping surface. There is at least one pair of clamping members, each one of the clamping members being movable towards a respective base clamping surface to thereby clamp a lead frame of the die assembly. A die assembly support is disposed between the pair of opposing base walls and the die assembly support and pair of opposing base walls provide a cavity. There is a position sensor coupled to a controller and there is also a drive that is controllable by the controller. The drive provides movement of the die assembly support relative to each the base clamping surface to thereby adjust a depth of the cavity. In operation, after the lead frame is clamped between the base clamping surface and clamping members, the controller allows the drive to provide the relative movement until the position sensor detects that an underside of the lead frame has abutted the die assembly support.
