The second scheme is a metal film plate, and a functional pattern layer is arranged on the gauze. The similar product is that the functional pattern layer is combined with the gauze by electroplating, gluing, welding, depositing and the like. The second scheme has the problems that the limitation of selectable space of the thickness and the wire diameter of the gauze is large, and the woven graph is single.
