How to select a thermal gap pad when clamping force is limited: the ASTM D5470 impedance model explains why low-pressure conformability dominates contact resistance, plus a gap-hardness-thickness checklist.

A practical look at how hardness and compression interact with assembly tolerance, surface contact, and component load in power-module thermal interfaces.
Height variation and uneven mating surfaces can interrupt the thermal path between a component and its heat sink. This article connects gap filling, conformity, slab thermal resistance, and practical selection.
A bigger heat sink won’t fix high thermal resistance caused by a poor interface. See how a thermal gap pad conforms under low pressure to improve contact between components and heat sinks.
