A phase change material (PCM) TIM is a solid pad that softens near 50–60 °C to flow like grease and set a thin bond line — without paste's pump-out. How it works.

Thermal resistance (K/W) is steady-state; thermal impedance adds time or area — for a TIM it's °C·in²/W at a set thickness. How they differ and when each matters.

A TIM's W/mK measures bulk conductivity, not real cooling. Learn what W/mK means, why the datasheet number misleads, and what predicts junction temperature.

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.

Thermal paste is a conductive compound that fills the microscopic air gaps between a chip and its heat sink. Learn its types, W/mK ratings, and how it works.

A thermal pad is a soft, pre-cut thermal interface material that fills the gap between a chip and heatsink. Learn how they work, W/mK, types and how to choose.
