Claim Text:
1. An electronic device comprising: a substrate having first and second conductive traces on a first surface thereof, the first and second conductive traces being separated on the substrate by a gap therebetween; a light-emitting diode (LED) having first and second distinct electrical contacts on a first LED surface thereof, the first and second contacts being attached and electrically coupled to, respectively, the first and second conductive traces; a backside thermal pad disposed on a second surface of the substrate opposite the first surface; and at least one thermal via (a) extending from the first surface of the substrate to the second surface of the substrate and (b) thermally coupling one of the first and second conductive traces to the backside thermal pad, wherein (i) the backside thermal pad is electrically isolated from at least one of the first or second electrical contacts, (ii) the backside thermal pad has a thermal conductivity greater than 75 W/(m·K), (iii) the first and second contacts are bonded to the first and second conductive traces by an adhesive, the adhesive comprising at least one of a pressure-activated adhesive, an anisotropic conductive adhesive, a conductive adhesive, a non-conductive adhesive, a heat-activated adhesive, or a UV-activated adhesive, and (iv) the LED comprises a packaged LED.
