Thermal pads only reach their rated W/mK under compression, usually 20–30%. Learn to measure the gap, pick nominal thickness, and set the right mounting force.

Choosing a thermal interface material means matching W/mK, thickness, hardness and insulation to your gap and power budget. A step-by-step guide for engineers.

Gap fillers conform to large, uneven gaps; gap pads are the fastest drop-in; PCM gives the lowest resistance on flat, high-power lids. A design-in comparison.

A practical comparison of thermal pads and thermal paste — how each works, where each wins, and how to choose by gap size, W/mK and manufacturability.

Thermal interface materials fill microscopic air gaps between a chip and heatsink to cut thermal resistance. Compare TIM types, W/mK and how to choose one.
