Abstract:
A flexible interconnect structure (10) allows for rapid dissipation of heat generated from an electrical device that includes light-emitting elements (300), such as light-emitting diodes ("LEDs") and/or laser diodes. The flexible interconnect structure (10) comprises: (1) at least one flexible dielectric film (20) on which circuit traces (40) and, optionally, electrical circuit components (30, 32, 34, 36, 38) are formed and at least a portion of which is removed through its thickness; and (2) at least a heat sink (100) attached to one surface of the flexible dielectric film (20) opposite to the surface on which circuit traces (40) are formed. The flexible interconnect structure can include a plurality of such flexible dielectric films (20), each supporting circuit traces (40) and/or circuit components (30, 32, 34, 36, 38) and each being attached to another by an electrically insulating layer (70). Electrical devices or light sources having complex shapes are formed from such flexible interconnect structures and light-emitting elements (300) attached to the heat sinks (100) so to be in thermal contact therewith.

Abstract:
A circuit board with a heat-recovery function includes a substrate, a heat-storing device, and a thermoelectric device. The heat-storing device is embedded in the substrate and connected to a processor for performing heat exchange with the processor. The thermoelectric device embedded in the substrate includes a first metal-junction surface and a second metal-junction surface. The first metal-junction surface is connected to the heat-storing device for performing heat exchange with the heat-storing device. The second metal-junction surface is joined with the first metal-junction surface, in which the thermoelectric device generates an electric potential by a temperature difference between the first metal-junction surface and the second metal-junction surface.
Abstract:
A printed circuit board for use with a cooling device configured to cool at least one device is provided. The printed circuit board includes a substrate having a first surface and a second surface opposing the first surface; a ground plane on the first surface of the substrate, and circuitry in a circuit-region on the second surface of the substrate. The ground plane includes a patterned-region that is patterned with an array of holes. The circuitry is configured for use with the at least one device to be cooled. When a first side of the cooling device contacts the ground plane, and when the at least one device to be cooled contacts the circuitry, a reduced cross-sectional area of the patterned-region prevents heat from a second side of the cooling device from degrading performance of the at least one device.
