| 摘要 |
A printed circuit has at least two crossed or superimposed conductor path systems insulated from one another except at certain points of interconnection. The printed circuit comprises a support such as a polyester film, the upper face of which has a system of conductor paths and contact areas and the lower face of which also has a system of conductor paths, these systems being formed by serigraphic deposition of conductive ink and polymerization of these inks, with connections between the two systems being formed by holes in the support, the walls of which are at least partly covered by polymerized conductive ink. The invention is in particular concerned with flexible printed circuits and their methods of manufacture. |
