发明名称 Integrated circuit package with etched leadframe for package-on-package interconnects
摘要 Methods, systems, and apparatuses for integrated circuit packages, and for package stacking, are provided. An electrically conductive frame is attached to a first surface of a substrate. The electrically conductive frame includes a perimeter ring portion, a plurality of leads, and a plurality of interconnect members positioned within a periphery formed by the perimeter ring portion. Each interconnect member is coupled to the perimeter ring portion by a respective lead. A first end of each interconnect member is coupled to the first surface of the substrate. An encapsulating material is applied to the first surface of the substrate, without covering a second end of each interconnect member with the encapsulating material. The perimeter ring portion is removed from the electrically conductive frame to isolate the plurality of interconnect members. A first integrated circuit package is formed in this manner. A second integrated circuit package may be mounted to the first package. Signals of the first package may be electrically coupled with the second package at the exposed second ends of the interconnect members. Side surfaces of the interconnect members may be exposed at sides of the first package.
