发明名称 METHOD OF PACKAGE STACKING USING UNBALANCED MOLDED TSOP
摘要 A semiconductor package assembly is disclosed including a pair of stacked leadframe-based semiconductor packages. The first package is encapsulated in a mold compound so that the electrical leads emanate from the sides of the package, near a bottom surface of the package. The first package may be stacked atop the second package by aligning the exposed leads of the first package with the exposed leads of the second package and affixing the respective leads of the two packages together. The vertical offset of leads toward a bottom of the first package provides a greater overlap with leads of the second package, thus allowing a secure bonding of the leads of the respective packages.
