Abstract:
An improved multi-chip module includes a main circuit board having and array of electrical interconnection pads to which are mounted a plurality of IC package units. Each IC package unit includes a pair of IC packages, both of which are mounted on opposite sides of the package carrier. The package units may be mounted on one or both sides of the main circuit board. A first primary embodiment of the invention employs a laminar package carrier having a pair of major planar surfaces. Each surface incorporates electrical contact pads. One IC package is surface mounted on each major planar surface, by interconnecting the leads of the package with the contact pads on the planar surface, to form the IC package unit. A number of other vriations exist that provide various other embodiments of the invention including one in which the carrier leads are laminated directly to the leads of an IC package.
Abstract:
A package carrier (100) for increasing the circuit density on printed circuit boards (503). The package carrier (100) mounts on a printed circuit board (503) on top of a first integrated circuit package (507) that is also mounted on the printed circuit board (503). The carrier (100) has an upper major surface (102U) having a pad array on which a second integrated circuit package (501) is mountable. The carrier (100) has a plurality of leads by means of which the carrier (100) is surface mounted to the printed circuit board (503). Each carrier lead is also electrically connected to a single pad of the pad array on the upper surface (102U). The integrated circuit package (507) beneath the carrier (100) shares all or most printed circuit board (503) connections in common with the carrier (100) and consequently the integrated ciurcut package (501) mounted upon the carrier (100). The carrier (100) also includes heat sink or heat disipation structures.
