Title (EN) PROCESS FOR MAKING FINE CONDUCTOR LINES
(FR) PROCEDE DE FABRICATION DE FINES LIGNES CONDUCTRICES
Abstract:
(EN) A process for producing conductor lines for electrical circuits, which process enables high packing density of the conductor lines and is adaptable to a large number of different conductors and support materials. The process comprises producing a powder image of a conductor line pattern by means of a preferably photographically prepared, positive, tacky pattern on an intermediate support; removing the tacky pattern, and transferring the powder image onto a final support, the powder image being consolidated into a conductor line pattern either before or after the transfer by sintering.
(FR) Procédé de production de lignes conductrices pour circuits électriques, ledit procédé permettant une densité élevée d'implantation de lignes conductrices et il est adaptable à un grand nombre de conducteurs et de matériaux de support différents. Le procédé consiste à produire une image de poudre d'une configuration de ligne conductrice au moyen, de préférence, d'une configuration positive collante préparée photographiquement sur un support intermédiaire, à retirer la configuration collante, et à transférer l'image de poudre sur un support final, ladite image étant consolidée dans une configuration de ligne conductrice soit avant soit après le transfert par frittage.
