Abstract: Integrated circuit device packages and substrates for making the packages are disclosed. One embodiment of a substrate includes a planar sheet of polyimide having a first surface, an opposite second surface, and apertures between the first and second surfaces. A planar metal die pad and planar metal are attached to the second surface of the polyimide sheet. The apertures in the polyimide sheet are juxtaposed to the leads. A package made using the substrate includes an integrated circuit device mounted above the first surface of the polyimide sheet opposite the die pad. Bond wires are connected between the integrated circuit device and the leads through the apertures in the polyimide sheet. An encapsulant material covers the first surface of the polyimide sheet, the integrated circuit device, the bond wires, and the apertures. The die pad and leads are exposed at an exterior surface of the package.

Abstract: A melt distribution block for feeding melt through an extrusion die to an extrusion passage. The melt distribution block has a generally annular body with inner, outer, front and rear faces. The front and rear faces include a series of flow divider channels therein extending generally radially inwardly from an inlet and terminating in a plurality of feed spirals. The feed spirals curve radially inwardly from the flow divider channels to encircle the inner face and narrow toward a radially inwardly disposed end. The feed spirals on the front and rear spaces curve in respectively opposite directions. An inlet port extends into the outer face and fluidly communicates with the inlet of the flow divider channels. A melt distribution die includes an axially stacked array of melt distribution blocks interspersed with separator blocks extending radially about a centrally disposed mandrel to define an extrusion and passage therebetween.

Abstract: Methods of making integrated circuit device packages and substrates for making the packages are disclosed. An embodiment of a method of making a substrate includes providing an unpatterned sheet of polyimide material having a first surface and an opposite second surface. A planar metal layer is attached to the second surface of the polyimide sheet. The metal layer is patterned to form an array of package sites, with each site including a planar die pad and planar leads. Apertures are formed through the polyimide sheet, either before or after attaching the metal layer. Each aperture is juxtaposed with a lead allowing access thereto. A method of making a package using the substrate includes mounting an integrated circuit device above the die pad (e.g., on the substrate or on the die pad through an aperture in the substrate). Bond wires are connected between the integrated circuit device and the leads through the apertures.

Abstract: An electronic assembly (20) having an insulated metal heat sink (10) and a method of manufacturing the electronic assembly (20). The electronic assembly (20) has a heat dissipater (11), a dielectric material (12), and a conductive layer (13). A semiconductor chip (21) is attached to the insulated metal heat sink (10). Heat generated by the semiconductor chip (21) is conducted to the conduction surface (14) of the heat dissipater (11). In one embodiment a convection surface (16) of the heat dissipater (11) is present and the heat is transferred from the convection surface (16) of the heat dissipater (11) to a fluid by convection. The fluid is directed by a manifold (64).
