Semiconductor package system with cut multiple lead pads
Abstract:
A semiconductor package system includes: providing a leadframe having inner frame bars, outer frame bars, a die pad, tiebars, and rows of leads, the inner frame bars being coplanar with outer frame bars; attaching a semiconductor chip to the die pad; attaching bond wires between the semiconductor chip and the rows of leads; encapsulating the semiconductor chip, the bond wires, the inner frame bars, the outer frame bars, the die pad, the tiebars, and the rows of leads in an encapsulant; cutting a groove to remove the inner frame bars; and singulating the leadframe and the encapsulant to remove the outer frame bars.
