Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 7:
8. An electronics assembly comprising:
a circuit board comprising:
a substrate;
a die mounted on the substrate;
a heat sink that is thermally connected to the die; and
a thermal lid between the die and the heat sink; and

an optical module for converting communication between optical signals and electrical signals, the optical module comprising:
a heat spreader that is structurally connected to the circuit board and extends from inboard of the substrate to outboard of the substrate thus overlapping the substrate, wherein:
the heat spreader is thermally connected to the heat sink; and
a side of the heat spreader that is thermally connected to the heat sink is coplanar with the surface of the thermal lid that is thermally connected to the heat sink; and

an optoelectronics assemblage that is thermally connected to the heat spreader and is wholly outboard of the substrate thus not overlapping the substrate, wherein the optoelectronics assemblage comprises an integrated circuit and a lens configured for optical communications.
