Abstract

1384951 Semi-conductor devices BBC BROWN BOVERI & CO Ltd 9 March 1972 [11 March 1971 20 July 1971] 11148/72 Heading H1K A semi-conductor device is mounted between two thrust members on which bear two spring biased rigid pressure members and on each side of the device the contacting surfaces of the thrust and pressure members have different radii of curvature, the smaller radius of curvature being sufficiently great that rolling motion can take place during the application of a clamping force. As shown, Fig. 2, a semi-conductor device 7 secured between carrier plates 8, 8<1> which may be of Mo is positioned between a pair of thrust members 5, 6. Pressure members 1, 2 are urged towards one another by spring loaded bolts 10, 11 and apply pressure to domed surfaces on the thrust members 5, 6, which can roll to ensure that the pressure is applied evenly across the device. Members 5, 6 also act as cooling members and may contact the carrier plates 8, 8<1> through ductile foils 9, 9<1>. Layers 23, 24 of titanium carbide, a polyamide or other suitable plastics material may be applied to the pressure members 1, 2 to provide a friction brake surface which, together with resilient members F1, F2 provided on the edges of the pressure members 1, 2, protect the device against lateral impacts. Alternative configurations of the pressure transmitting surfaces between the thrust members and the pressure members are illustrated in the insets A, B and C. The ball shown in variant C may be replaced by a lens shaped body. A stack of semi-conductor devices and thrust members may be arranged between the clamping members.
