Most pcb dielectric materials have a thermal conductivity in the range of 0 3 to 0 6 w m ºc which is quite low compared to copper whose k is 386 w m ºc. A printed circuit board pcb is a board made of different heat resistant insulating materials. The heat conductive properties of a pcb are referred to as thermal conductivity k.
Conductive copper tracks are printed or etched onto this con conductive base substrate.
Therefore more heat will be carried away quickly by copper plane layers in a pcb than by the dielectric material. Pcb materials for base of a printed circuit board can be resin based fiberglass based epoxy glass metal board flame retardant ul94 vo ul94 v1. Density is another important property of your pcb that is typically associated with the dielectric material. Before tackling the impact of pcb material properties on your board s manufacture we need to know what they are.
