Abstract

1524331 Semiconductor devices BROWN BOVERI & CIE AG 23 Feb 1977 07558/77 Heading H1K A semiconductor device 1 having thermal and electrical contacts 2, 2<SP>1</SP> is clamped between two pressure plates 4, 11 connected by four rods 6 acting via part-spherical washers 9 in countersunk portions of the one plate 11, wherein at least one pressure plate 11 is a square spring plate with a screw-threaded insert 12 guiding a screw 13 which acts on a convex thrust member 8 on one contact 2<SP>1</SP>. The other pressure plate 4 may be a heat dissipating crossmember or it may be a spring plate of another semiconductor device in a stack. The contacts 2, 2<SP>1</SP> or the pressure plate 4 may be part of a heat pipe. The spring plate 11 has flat characteristics so that a large range of compressive forces can be applied by it.
