Abstract (en)
[origin: WO8503605A1] According to the process, there is applied to one face of a relatively rigid isolating support (1) a first matrix arrangement of areas (3) connected by conductor tracks of lines (4). Said arrangement is coated with a thin layer of isolating lacquer (5) and a second matrix arrangement of areas (6) is set in place on the lacquer layer with their conductor tracks of columns (7) to obtain, by bringing together an armature towards each stud comprised of two areas (3, 6), a capacitive connection.
Abstract (fr)
Conformément au procédé, on applique sur une face d'un support isolant relativement rigide (1), un premier arrangement matriciel de plages (3) reliées par des pistes conductrices de lignes (4). On recouvre cet arrangement d'une mince couche de vernis isolant (5) et on met en place sur la couche de vernis un deuxième arrangement matriciel de plages (6) avec leurs pistes conductrices de colonnes (7) pour réaliser, par rapprochement d'une armature vers chaque plot formé de deux plages (3, 6), une liaison capacitive.
