International Classification:

H02G003/08
H05K005/00

US Classification:

174 521, 361760, 361761, 361773

Abstract:

A power converter includes electrical contacts arranged on a first surface and a connection device. The converter has a top surface above the first surface and a bottom surface below the first surface. A border of the bottom surface is inset from a border of the second surface. The connection device includes a pair of conductive legs, each leg comprising a first end and a second end. The pair of legs lie opposite each other in a pair of evenly spaced planes that intersect the first surface. The first ends are adapted to connect to one or more of the contacts on the first surface and the second ends are adapted to connect to one or more conductive pads on a surface of a substrate. The connection device is adapted to enable the first ends of the two legs to connect to the contacts from below the first surface.

International Classification:

H01L 21/00

US Classification:

438127, 438126

Abstract:

Power conversion apparatus can include a circuit board with power conversion circuitry and a package. The package may be formed by encapsulating areas of the circuit board assembly either before or after the interface contacts are attached to the circuit board. A method for encapsulating two sides of a substrate can include providing a mold that fills a larger first cavity to create a sealing force on a smaller second cavity. The encapsulant flows through the first cavity into the second cavity. A thermal extender can include a surface for mounting a heat dissipating power converter and a surface for mating with an external circuit board. Interface conductors may mate with contacts on the heat dissipating power converter and with conductive regions on the external circuit board. A heat sink may be thermally coupled to remove heat generated by the power converter.

Abstract:

This document describes apparatus and methods for a self-contained assembly having an encapsulated electronic module coupled to a heat removal device by a thermally conductive substance. In an illustrative example, the module includes at least one heat dissipating device thermally coupled by internal members to selected portions of a housing. The module housing includes a flat top surface with a perimeter adjoined to side surfaces. In one example, the heat removal device includes a cavity interior surface with an upper surface to match the module top surface, and side walls that match at least 50% by area of the selected portions of the module side surfaces. The cavity interior surface may receive at least 50% of the housing surface area. The matched portion of the cavity side surfaces may be at least 33% by area of the portion of the cavity upper surface that matches the module top surface.
