Thermal Conductivity
Definition
Ability to transfer heat, key for heat-dissipating tapes.
Historical Background
1990s: thermally conductive tapes replaced bulky metal conductors.
Example
Thermally conductive tape between CPU and heat sink rapidly transfers heat.
Formula
Thermal Conductivity (W/m.K) = Heat Flow x Thickness / Area x Temp Diff
Core Concepts
Phonon conduction through molecular chains. Fillers enhance it.
Extended Applications
Ordinary: 0.2; conductive: 1-3; high: 5-10; ultra-high: 20-30 (5G); graphene: 100+ W/m.K.
