摘要:
A lead frame for a semiconductor package has a flag to which a semiconductor die is mounted. Tie bars are coupled to the flag. There is a first set of leads and each first set lead in the first set of leads has a first set lead parallel length and a first set lead tapered length. The first set lead parallel length of each first set lead has a constant width and edges that are parallel to edges of all other first set lead parallel lengths. A free end region of the first set lead tapered length of each first set lead provides a first set lead bond target region. There is a second set of leads disposed between a first one of the tie bars and the first set of leads. Each second set lead, in the second set of leads, has a second set lead parallel length and a second set lead tapered length. The second set lead parallel length of each second set lead has a constant width and edges that are parallel to edges of all other second set lead parallel lengths in the second set of leads and also parallel to the edges of first set lead parallel lengths. At least one second set lead has an extension length extending inwardly from the second set lead tapered length, the extension length has a constant width and provides a second set lead bond target region. Wire bond leads electrically couple both the first set lead bond target region and second set lead bond target region to respective die external electrical connection pads on a surface of the die and a package body encloses the die.
