A heat sink and method for heat sinking a package containing electronic components is described. The heat sinking is accomplished by use of a cooling plate located beneath a circuit board. The package having leads extending from more than one side of the package is positioned on the cooling plate so that the leads from the sides of the package can be electrically coupled to conductors on the circuit board wherein the circuit board is disposed about at least two and preferably three sides of the package. The package is secured to the cooling plate by a spring clip. The spring clip permits flexible positioning of the package relative to the cooling plate including positioning the package in close proximity of the edge of the cooling plate. Thermal conduction between the package and the cooling plate can be enhanced by the presence of a compressible thermally-conducting material. The circuit board preferably has an opening therein so as to permit the board to be in close proximity to the three sides of the package for increased connectibility.

Apparatus and method for improved thermal coupling of a semiconductor

A container for a semiconductor device has a metal plate and a body of synthetic resin which encapsulates a part of the plate, keeping a large surface thereof exposed. In the area separating the part encapsulated within the body of resin and the part without the resin, the plate has two opposed side notches and at least one groove connecting them.

High reliability metal and resin container for a semiconductor device

Method for making an insulating package premolded on a metallic frame with electrical contacts containing in an inner space a semiconductor chip which rests on a thermic dissipator and is connected to the electrical contacts. The inner space of the package is closed on top by a cover provided with a lateral extension with a bent end, which operates not only as a cover, but also as a means for fastening and thrusting the package toward a support surface.
