Abstract: A metal pallet is integrated within a circuit board using a process similar to a multilayer PCB, which integrates the metal pallet into the circuit board at the same time as the supporting layers are fabricated. The use of B-stage material provides a bonding mechanism for the metal pallet to be embedded within the circuit board, creating a cohesive integrated part. Embedding the pallet during the fabrication process, pre-lamination, generates a more robust construction and connection not impacted by post fabrication process in assembly. After assembly the circuit board with embedded metal pallet can be mounted directly on a heat sink, cool ribbon or other feature required to help remove heat. The planar back side surface provides a more robust mounting of the metal pallet than a post fabricated assembly as used in conventional techniques.

Abstract: This document describes techniques and apparatuses that implement a high thermal conductivity region for optoelectronic devices. In some embodiments, a printed circuit board (PCB) includes a high thermal conductivity region that extends through the PCB. The high thermal conductivity region has first and second surfaces that are approximately coplanar with exterior layers of the PCB. A side-emitting optoelectronic device is mounted to the first surface of the high thermal conductivity region via conductive material that enables conduction of the device's heat into the high thermal conductivity region. The high thermal conductivity region can then transfer the heat away from the device and toward the second surface of the high thermal conductivity region, thereby improving the device's thermal performance.
