A Compute Module uses the enclosure as a heat-spreading surface. Which mechanical and thermal checks help avoid a design that cools well on one sample but places excessive load on the module or board connectors?

Re: How should a Compute Module enclosure handle heat without stressing the connectors?
#2Use the official mechanical dimensions and mounting guidance for the module and carrier. Build a tolerance stack for board height, standoffs, enclosure and thermal interface material. A nominal CAD fit does not show the contact pressure at manufacturing extremes.

#3Measure temperature under the sustained workload while checking the interface's specified compression range. Keep mechanical support deliberate so the connector is not relied on as a clamp. Allow for electrical isolation where the chosen thermal material or enclosure requires it.

#4Evaluate assembly repeatability, thermal cycling and service access as well as the best-case temperature. Record the exact pad or interface specification with the enclosure revision. A thicker material may accommodate tolerances but can change thermal resistance and contact force.
