Method for application of electrically-conductive structure to insulating substrate e.g. for electrical circuit board manufacture, using laser energy for transfer of metal by vaporization

摘要

The method has a laser beam (4) provided by an IR laser, a CO2 laser, a Nd-YAG laser or a diode laser directed onto the surface of a transparent carrier foil (2) coated with a mixture (3) of a metal powder and an organic residual substance, for transfer of the metal to the surface of an underlying insulating substrate (1) by vaporization of the metal and condensation on the substrate surface. An independent claim for a substrate provided with an electrically-conductive structure is also included.
