square millimeter kelvin per watt

Areal thermal resistanceexact by definition

The square millimeter kelvin per watt is 10⁻⁶ m²·K/W, the unit used inside semiconductor packaging where the areas are die-sized. A die-attach layer at 5 mm²·K/W under a 100 mm² die contributes 0.05 K/W to the junction-to-case path.
