Номер: DE0002928212A1
Принадлежит:

The insulator suitable for carrying heat dissipating members for a disc shaped thyristor contains a metal bush (1) into which screws a rod. The bush is mounted on a lower member, and the rod passes through an upper member and carries members which hold down the upper member. The metal bush has a bottom flange (1b), and the whole is embedded in insulating material (3). This material extends above the bush and includes external cooling ribs (3b), while the base is stepped to match the bush inside. This includes a larger diameter portion (3d) which carries an outer metal ring (2) which assists its keying into the lower member. Its top surface is flush with that of the lower member, and the cooling ribs are above it. The metal parts are of non-magnetic metal and the insulating material may be of ceramic or a glass fibre reinforced substance.

Low thermal resistance coupling is provided between electronic components and a main heat sink by the expedient of providing individual, adjustable height pillars between them. Each pillar comprises a bifurcated body and a detachable head. The head is attached to the hot component by means of silver loaded epoxy. The height of the pillar may subsequently be adjusted, the component attached to a circuit board, and the pillar secured by establishing an interference fit between the pillar and the walls of its mounting hole. Thermal resistances of less than 6.5.degree.C/Watt are achieved between a semiconductor junction and a heat sink coupled in this way.

A mounting structure is provided which is capable of easily attaching a heat sink irrespective of a thickness of an LSI (Large-Scale Integration circuit) mounted on a printed circuit board. Each female screw metal fitting of each female screw portion is attached on an upper surface of a cylindrical gel in a stacked manner and a lower surface of the cylindrical gel is attached to the printed circuit board. An end portion of each male screw is made to pass through each through-hole of the heat sink so as to be screwed into each of the female screw portions. With a progress of screwing therein, each of the female screw portions is elevated and the cylindrical gel is pulled and elongated. Since a restoring force occurs when the cylindrical gel is elongated, the heat sink is pulled by each of the female screw portions toward the LSI. Thus, variations in height can be accommodated.

Assembly-heat sink for semiconductor devices

Номер: GB0002129215A
Принадлежит:

The present invention is directed to an assembly-heat sink for semiconductor fusions. The fusions are disposed within the assembly-heat sink between cylindrical metal members which both cool the fusions and facilitate making electrical contact to the fusions. Top and bottom members of the assembly-heat sink, which entirely enclose the cylindrical members and the fusions are comprised entirely of metal permitting the assembly-heat sink to be cooled from three sides. The fusions are electrically insulated from the top and bottom members of the assembly-heat sink.
