摘要:
The present invention relates to an apparatus and method for dissipating heat from high-power electronic devices. The assembly includes a high-current substrate, such as a printed circuit board supporting an electronic device, a heat pipe thermally coupled with the electronic device and an assembly case which also forms a heat sink, and thermal transient suppression material which may be thermally coupled with the electronic device and the heat pipe.

An overmolded electronic package includes a circuit-carrying substrate and a connector housing or shroud interconnected via a suitable interconnection arrangement. Some embodiments may include a backplate affixed to the substrate and, in some cases, also to the connector housing or shroud. In some embodiments, the connector housing or shroud may be affixed to the substrate, and in any case the entire subassembly of components is overmolded with a rigidly formable molding compound to bond together all components of the subassembly and form the overmolded electronic package. The subassembly of components with the exception of the backplate may alternatively be overmolded with the molding compound, and a backplate thereafter affixed to the subassembly via a compliant bonding medium.

An improved overmolded electronic assembly includes a backplate provided with a recessed edge, a circuit substrate on the backplate, at least one electronic component mounted on the circuit substrate, conductive traces on the circuit substrate which together with the electronic component(s) defines a circuit device, an electrical connector, and an overmold body that has peripheral edges that wrap around sides of the backplate and onto the edge recesses. The resulting over wrap feature eliminates delamination problems that would otherwise occur during thermal cycling of the electronic assembly, improves corrosion resistance at connector-to-backplate interfaces, and enhances securement of the printed circuit board assembly and electrical connector to the assembly.

An encapsulated microelectronic package includes a fluid conducting cooling tube directly coupled to one or more semiconductor chips, with the encapsulant being molded over the semiconductor chips and portions of the cooling tube in proximity to the semiconductor chips. The encapsulant immobilizes the cooling tube with respect to the semiconductor chips, and the cooling tube and encapsulant are designed to minimize differences in their coefficients of thermal expansion relative to the semiconductor chips.
