Abstract
The subject disclosure relates to a process for producing electrically conductive surfaces on insulating substrates which comprises use of a laser beam to melt tracks onto said substrates into which conductive particles are simultaneously impinged, resulting thereby in the formation of computer controlled patterns designed according to tracings characteristic of those used in the manufacture of electric/electronic circuit boards.
Claims7
A method of producing electrically conductive surfaces on insulator surfaces characterized in that it uses a laser beam to melt tracks onto said insulator surfaces which are simultaneously impacted upon by conductive particles which, upon fusibly bonding to said molten insulator surface, constitute an electrical conductor.
