Metal Core Boards - Thermal Conductivity

Thermal conductivity is the ability materials or a material that reports its ability to conduct heat. In terms of MCPCB, heat conductivity refers to how the metal core reacts to heat and which levels of heat.

Thermal conductivity is calculated by the amount of heat transmitted over a certain period of time through thickness in a direction along the surface of an area as a result of temperature differences. Controlled conditions are maintained for the calculation and the heat transfer depends only on the temperature gradient/change.

The thermal conductivity of the metal core has been represented as the symbol K. A more common and modern symbol for it is the Greek lambda, used extensively in Fourier's Law.
