Abstract:
1. A light emitting diode (LED) carrier assembly, comprising: an LED die mounted on a silicon submount; a middle layer disposed below the silicon submount, the middle layer consisting of a material that has both thermally conductive and electrically isolating properties; a metal clad layer disposed between the silicon submount and the middle layer a thermal pad and two electrical pads disposed between the silicon submount and the metal clad layer, wherein an entirety of the thermal pad is disposed between the two electrical pads; at least one via extending through the middle layer, the via containing Cu, Au, or Ag, wherein the at least one via is electrically coupled to at least one of the two electrical pads; and a printed circuit board (PCB) disposed below the middle layer, wherein the middle layer is bonded with the silicon submount and the PCB.
