摘要:
The present disclosure provides systems and methods for a package securing system including a top plate, an alignment frame, a gasket, and a back plate. The top plate comprises a thermal conductive member to transfer heat from a central processing unit (CPU) and secure the CPU to a ball grid array (BGA) socket and a printed circuit board (PCB). The alignment frame is configured to align a connection between the BGA socket and the PCB. The gasket is to seal the CPU, the BGA socket, and the alignment frame between the PCB and the top plate. The back plate is configured to couple with the top plate through the PCB.

An electronic device may have a metal electromagnetic interference shielding enclosure. The enclosure may have a bottom wall, vertical sidewalls that extend upwards from the bottom wall, and a lid that covers the enclosure to define an interior cavity. Power supply components and other electrical components may be mounted within the interior cavity. A printed circuit board on which integrated circuits and other components are mounted may have an upper surface that faces the bottom wall of the enclosure and an opposing lower surface that faces a metal plate. Fence structures may be used to help shield components mounted on the printed circuit. Heat may be dissipated from components on the printed circuit into the bottom wall and into the metal plate. A plastic housing may be used to house the shielding enclosure, printed circuit board, components mounted on the printed circuit board, and the metal plate.

The present invention is a method for fixing electronic components. Since the invention removes a step for coupling an existing metal printed circuit board (Metal PCB) and a thermally conductive compound to a heat sink by directly fixing electronic components to the heat sink using the thermally conductive compound, a manufacturing process can be simplified and thus manufacturing costs can be reduced. In addition, the invention can more efficiently transfer heat generated from the electronic components to the heat sink.

摘要:
A precursor structure for fabricating light sources, the light sources fabricated therefrom, and the method of fabricating the precursor structure are disclosed. A precursor substrate includes a flexible printed circuit board on which dies are bonded and a separation ridge. The flexible printed circuit board has a bottom heat-conducting layer, an insulating layer, and a circuit layer. The insulating layer and the circuit layer include a plurality of openings that expose the top surface of the heat-conducting layer. The separation ridge extends above the circuit layer and the dies and is configured to prevent contact with the dies and any structures constructed above the dies when the precursor substrate is in contact with a surface positioned over the die and in contact with the separation ridge. The structure is well suited for roll-to-roll processing equipment.
