Example Embodiment

[0043] figure 1 It is a schematic diagram of the structure of the single-layer substrate of the chip module of the present invention. A metal composite plate 23 is covered with an insulating layer 22. The insulating layer is a metal compound of the metal composite plate, that is, an oxide film layer or a nitride film layer, or an insulating ceramic material or polymer material deposited on the metal composite. The surface of the plate 23. The insulating film 22 can be used to replace the known composite substrate, that is, as an electrical insulator between the circuit layer 21 and the metal composite sheet 23. For example, an aluminum-based composite material is used as the material of the metal composite plate 23, and an insulating film layer of aluminum oxide or aluminum nitride is formed on the surface of the aluminum-based composite material. It can be seen from Table 1 that the thermal conductivity of aluminum is 237W / MK, aluminum oxide is 46W / MK, and aluminum nitride is 1...

Abstract

The chip module consists of a high thermal diffusivity base board, at least one chip mounted on base board. The high thermal diffusivity base board is made by forming insulation layer on metal compound material sheet and then mounting copper wire layer on the insulation layer. The copper wire layer can be used in adhering chip. For the material of base board, the aluminum base with high coefficient of heat-transfer is selected.

Description

technical field [0001] The invention relates to a high heat dissipation chip module and its substrate, in particular to a laminated circuit board in which the chip module uses an aluminum-based composite material to form a metal composite plate. Background technique [0002] With the gradual development of electronic products in the direction of high performance, high frequency, high speed and thinness, under the design concept of light, thin, short, small and multifunctional, various electronic related main components such as central processing unit ( CPU), chipset (Chipset), etc. are all researched and developed in the direction of high speed, multi-function, high power, and small size. Therefore, the calorific value per unit volume in the components is constantly increasing, and the heat dissipation of the components has become the key to the continued development of the electronics industry. [0003] The performance of integrated circuit (IC) chips continues to improve ...
