Good day to all,
Does anyone know of or have a formula for calculating the "natural" thermal
(heat) dissipation of an external plane area for 1 oz FR4 based material.
We are in the process of using an external (Primary or Secondary) layer heat
sink plane for a regulator type device on a multi layer design and require a
means of calculating the required area based on its power requirements.
This design is for a general / commercial Class 1 or 2 application using
convection type heat dissipation supplemented with a forced (fan)
convection.
Any help would be greatly appreciated.
Regards, Greg.
