Processo de fabricação de um elemento aquecedor por depósito de camadas finas sobre um substrato isolante e o elemento obtido

摘要

A method for fabricating a heating a element includes modifying the surface state of a substrate in order to obtain at least one smooth area of low roughness and at least one rough area having a higher roughness; applying a highly electrically conductive material to these various areas; and connecting smooth area(s) of the conductive material to an electrical power source.
