In Fig. 1, a large-scale integrated chip 10 is contacted by a cylindrical piston 12 split into a first half 14 and a second half 16. A hat-shaped member 18 encloses the piston and is suitably secured to a substrate 20 on which the chip 10 is mounted. A flat spring 21 is positioned between the members 14 and 16 and urges them against the member 18. The spring 21 also engages the chip and further contributes to the removal of heat from the chip. The spring may be made from a high thermal conductivity spring alloy. (The spring further contributes to better thermal conductivity between the pistons 14, 16 and the member 18. The additional points of contact between the chip and the members 14, 16, and 21 improve heat removal.
