Pcb Material Properties. Conductive copper tracks are printed or etched onto this con conductive base substrate. 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.
Your pcb material properties will determine the electrical mechanical and thermal behavior of this board. Conductive copper tracks are printed or etched onto this con conductive base substrate. 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.
The heat conductive properties of a pcb are referred to as thermal conductivity k.
We consider several factors including thermal electrical chemical and mechanical properties of different pcb materials and choose the right type that rightly supports the design and application. The significant properties may be classified as mechanical electrical thermal or chemical. The heat conductive properties of a pcb are referred to as thermal conductivity k. Dielectric density and thickness are also important in setting your board impedances.
