    摘要: A lead frame for a semiconductor device has a die flag and leads that surround the die flag. In order to decrease the distance or spacing between inner lead ends and the die flag, which allows for short bond wires for connecting the inner lead ends to a die mounted on the die flag, at least some of the leads are twisted along their lengths to be angled with respect to a die-flag plane. The pitch between such twisted leads can be reduced without resulting in physical contact between adjacent leads, enabling the leads to extend further towards the die flag.

    摘要: A mold (10) including a first mold part (12) and a second mold part (14) define a mold cavity (16) therebetween. A gate (18) is formed in at least one of the first and second mold parts (12) and (14) such that the gate (18) communicates with the mold cavity (16). A vent (20) having a constricted portion (22) is arranged to communicate with the mold cavity (16). A substrate (28) including a base substrate (30) and an electrically conductive pattern (32) and (34) formed on the base substrate (30) may be received in the mold (10). A solder resist layer (36) is formed on the base substrate (30) and a portion of the electrically conductive pattern (32). A plurality of grooves (38) and (40) is formed in a staggered arrangement around a periphery of a molding area (42) on the substrate (28).

    摘要: 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.
