One topic at a time, published quarterly — drawn from problems we keep meeting on real programs.
How hot is a surface allowed to get?
A specification with "43°C" on one line is usually wrong. Why the allowable temperature depends on contact duration and surface material, and how to set a defensible design target.
Read moreWhy datasheet conductivity is the wrong way to pick a TIM
A 6 W/m·K product can perform worse than a 3 W/m·K one. Here's why resistance — not conductivity — is the number that matters, and how to compare candidates properly.
How far can air cooling go — and where liquid takes over
"How many watts can air handle" has no answer. Convert heat flux and allowable temperature rise into a required heat transfer coefficient, and check what to settle before switching.
Vapor chamber or heat pipe — which problem are you solving?
Both move heat by phase change, but they solve different problems. Start by deciding whether spreading or transport is your bottleneck.
