Title: Cooling unit for integrated circuit
Inventor: HAGIWARA TAKASHI
IPC: H01L23/46
Filed: 1985-08-23
Abstract: PURPOSE:To largely decrease thermal resistance, by forming minute gaps between integrated circuit and the surface of thermally conductive fluid layer, with volume contraction of the thermally conductive fluid. CONSTITUTION:For an integrated circuit 3, treatment for the prevention of soldering-wetting is performed in advance before soaking them in a molten soldering layer. After soaking the integrated circuit 3, that is, after placing a substrate frame 5 on a cooling container 1, heating the cooling container 1 is interrupted. This interruption of heating allows the temperature of molten solder in the cooling container 1 to gradually fall, and the cooling solidification of the molten solder proceeds together with volume contraction by said temperature fall. Because the treatment for the prevention of soldering-wetting is performed on the integrated circuits 3, minute gaps 8 are formed by volume contraction of the molten solder between the surface of a solidified soldering layer 2 and the integrated circuits 3. An outer peripheral lower end surface 5a of the substrate frame 5 is brought in contact with an outer peripheral upper end surface of the cooling container 1 and they are fixed jointly by the use of fixing screws 6 and 6. Hence, thermal resistance can be largely decreased.
