Abstract

A method and device for manufacturing of electrical components on a continuous web or discrete sheets of dielectric material are disclosed. The method includes feeding, from a supply roll of a laminated web or a supply of sheets including at least one unbroken layer of conducting material laminated on a flexible backing layer of dielectrical material, the laminated web or discrete sheets to a nip between a patterned cylinder and a cooperating cylinder, to shape the conducting layer into a repeated pattern of conducting material having ridges and valleys. The method further includes removing, by mechanical machining, conducting material from the thus shaped conducting layer. The removing is performed simultaneously with the step to shape the conducting layer, and by way of the cooperating cylinder, designed as a milling cutter cylinder.
