    摘要: A lead frame (10) for a quad flat non-leaded semiconductor package (606), includes a tie bar (12), a first group of leads (22) extending a first length from the tie bar (12) in a transverse direction (Y), and a second group of leads (24) extending a second length from the tie bar (12) in the transverse direction (Y). The second length is greater than the first length, and leads from the first and second group of leads (22, 24) alternate in a longitudinal direction (X) along the tie bar (12) so that the first and second groups of leads are staggered. The second group of leads (24) is displaced from the first group of leads (22) in a Z-direction (Z) perpendicular to both the transverse (Y) and longitudinal (X) directions. The leads of the first and second groups of leads (22, 24) each have a respective contact terminal (26 and 28) at their distal ends. The contact terminals (26 and 28) each have a contact face (40 and 42) in a contact plane (44).
