<p>A method for rapidly and accurately stripping certain areas (10, 11) of a printed circuit (6), both on conductors (3) and next to them. The areas to be stripped (10, 11) on a blank covered entirely or in part with an insulating coating (4, 5) are machined with a machining head having one or more laser beams controlled by a computer which receives the coordinates of said areas. The strength of the beam is modulated differently for the conducteurs (3) and the areas next to them, as well as when piercing the circuit or cutting around its edges. The method can be used for the manufacture of flexible printed circuits.</p> |
