Production of conductor tracks on plastics by means of laser energy
Abstract
A process for the production of electrically conductive layers on the
surface of plastics in which the surface of a plastic filled with
electrically conductive constituents is irradiated with laser energy in
such a way that the plastic is evaporated down to a predetermined depth at
the point of incidence by the laser energy, leaving behind the
electrically conductive constituents, which increase in concentration and
thus form an electrically conductive layer. With the aid of the process,
plastic moldings with integrated electrically conductive layers or tracks
on the surface can be produced, for example components used in the
electrical and electronics industries or other large or small plastic
parts of any desired shape which are provided with conductive elements in
certain places. The molding can also be a constituent of a composite
article with other materials.
