Abstract:
A package carrier comprising: a dielectric body having upper and lower parallel major planar surfaces; a first mounting pad array affixed to said upper major planar surface, said first mounting pad array sized to receive the leads of a first discrete integrated circuit package adjacent to said upper major planar surface;a second mounting pad array affixed to said lower major planar surface, each pad of said second array coupled to a pad of said first array by means of an internally plated aperture which extends between said upper major planar surface and said tower major planar surface; a set of carrier leads, each carrier lead conductivety bonded to a pad of said second array, said set of carrier leads spaced and configured for surface mounting on a printed circuit board; said package carrier forming a discrete unitary structure capable of being positioned on pads on a circuit board over a second integrated circuit package positioned on a printed circuit board; and a heat sink incorporated into said dielectric body and positioned on said lower major planar surface, said heat sink being a substantially flat member.
