Heatsink techniques for optical and electrical modules
A module for use in a hardware platform for networking, computing, and/or storage includes a printed circuit board assembly; components disposed on a primary side of the printed circuit board assembly; a primary side heatsink for a pluggable module, wherein the primary side heatsink is disposed to one or more pivot points on the pluggable module, for applying a uniform and controlled external force against the pluggable module. The module further includes a cage attached to the printed circuit board assembly for supporting the pluggable module, wherein the one or more pivot points are external to the cage.
1. A module for use in a hardware platform for networking, computing, and/or storage, the module comprising:
a printed circuit board assembly;
components disposed on a primary side of the printed circuit board assembly;
a primary side heatsink for a pluggable module, wherein the primary side heatsink is disposed to one or more pivot points on the pluggable module, for applying a uniform and controlled external force against the pluggable module, wherein the primary side heatsink is attached to a faceplate of the module via a sprung line-contact.
2. The module of claim 1 , further comprising a cage attached to the printed circuit board assembly for supporting the pluggable module, wherein the one or more pivot points are external to the cage.
3. The module of claim 2 , wherein the pluggable module and the cage are compliant to a multisource agreement (MSA).
4. The module of claim 1 , wherein the one or more pivot points include four points positioned adjacent to each corner of the pluggable module.
