Get Price2020-4-22u2002·u2002The moisture of the insulating plate on the surface of the insulating material has a very sensitive effect on its surface resistance. In particular, the adsorption force of water-absorbing substances such as polar materials on water is greater than the cohesion of water molecules, and it is easy to form a continuous water layer on the surface and reduce the surface resistance.
Get PriceHowever, instead of the usual fiberglass used in most PCB board types, aluminum circuit board make use of aluminum or copper substrate board. The aluminum backing is lined with thermally insulating material that is designed to have a low thermal resistance, meaning less heat is transferred from the insulating material to the backing.
