Microchip module mounting structure

摘要

An apparatus such as a portable computer including a microchip module constituted by a substrate and semiconductor chips mounted thereon. The microchip module is surrounded and supported by an annular frame. The microchip module and the annular frame are fixed to a motherboard by screws. A heat-radiating plate is attached to the microchip module to constitute a microchip module unit. The arrangement including the annular frame protects the microchip module from vibration and impact, and improves a grounding function, a heat radiating efficiency, and a shielding function.
