Leads from the solid state device are soldered to conductors on a printed circuit board which is attached to the chassis by a further threaded screw. Heat generated by the solid state device' is conducted via the support to be dissipated by the chassis
serving as a heat sink. However, the amount of heat which can be conducted away from the solid state device is limited.

The mounting means can be utilized to provide a quick and strong mount for solid state devices in close proximity to a printed circuit board.
Brief Description of the Drawings
One embodiment of the present invention will now be described by way of example, with reference to the accompanying drawings, in which:
Fig. 1 is a perspective view, partially in exploded form, of the preferred embodiment of the invention; and
Fig. 2 is an end view of the preferred embodiment of the invention, partly in section.
Best Mode for Carrying Out the Invention
Referring to Fig. 1, an elongated thermally conductive, support body 20 is shown having a substan¬ tially L-shaped cross section formed by a pair of legs 28 and 22, with leg 22 extending at a right angle from leg 28 and having an angled end portion 24. The legs 22, 28 may be of approximately equal length or, as shown in the drawings, of different lengths. In the preferred embodiment of the invention, the angle of the end portion is approximately 30 degrees. Leg 22 has a first flat surface 25 and leg 28 has a second flat surface 27. Each of a plurality of thermally conductive cap members 10 (shown individually in Fig. 1 as 10A, 10B) has an L-shaped cross section, and one leg thereof is provided with an angled surface 16 that is designed to mate with the angled end portion 24. An elongated opening 12, in each cap member 10, is adapted to receive a fastener, which may be a bolt 14. The bolt 14 contacts a receptacle in the form of a threaded opening 23 in the leg 22 (shown in Fig. 2). Each cap member 10, in the preferred embodiment of the invention, was of a width that permitted two solid state devices 30 to be mounted by the cap member. The solid state devices 30 are shown individually as 30A- 30D in Fig. 1. The cap members 10 may be made wider or narrower in width to permit either more or less solid state devices 30 to be mounted by each cap member.
Each solid state device 30, in the preferred embodiment, is comprised of a body section 32, a flat heat transfer plate 34, and electrical conductors
(leads) 36. The leads 36 extend from the solid state device to conductors 48 on an associated printed circuit board 40 (shown in Fig. 2).
Referring now to Fig. 2, a metallic chassis 50 provides the major heat sink to which the thermally conductive support body 20 is attached. The leg 28 is provided with an opening 26 through which a fastener 44 is inserted and which fastener also passes through an opening 42 in a printed circuit board 40 and an opening 52 in the chassis 50. The leg 22 extends through an opening 46 in the printed circuit board 40. The fastener 44 holds the second flat surface 27 of leg 28 in thermal contact with the chassis body 50, while also holding the printed circuit board 40 in a fixed relationship with respect to the chassis 50 and the support body 20.
To assemble, the solid state device 30 is positioned between the leg 18 of cap member 10 and the first flat surface 25 of the leg 22. As the bolt 14 is tightened downwards into the threaded opening 23 of the leg 22, the angled surface 16 slides downwards at an angle which causes the cap member 10 to move in the direction indicated by the direction of arrow B and in the direction indicated by the direction of arrow C. Movement in the B direction causes a force to be transmitted to the solid state device 30, which urges the heat transfer plate 34 into contact with the first flat surface 25 of the leg 22. Once mounted in this sandwiched fashion, the solid state device can transmit heat upwards through the leg 18 and then down through the leg 22 and through heat transfer plate 34 to the leg 22, and hence downward into the chassis 50.
The leads 36 are soldered to the corresponding conductors 48 on the circuit board 40 and if necessary, to remove a defective solid state device the leads 36, can be easily de-soldered and the bolt 14 disengaged so that the defective component can be removed and a new component installed.
In the preferred embodiment of the invention, the support member 20 and the lap members 10 were formed of aluminum which aluminum was finished black anodized.
