Device for the metallisation of printed forms which are equipped with electrically conductive tracks and associated metallisation method

摘要

The invention relates to a printed circuit which is equipped with electrically conductive tracks and which can be obtained by means of gravure printing. Gravure printing can be used to obtain conductive tracks of a very small thickness, such that said tracks have a high electrical resistance. In order to reduce the electrical resistance of the tracks ( 30 ) thus obtained, the invention consists in connecting at least two first electrodes ( 9, 8 ) to opposite portions ( 17, 18 ) of the same track while the middle ( 19 ) of said track is immersed in an electrolytic bath ( 7 ). Moreover, the bath is connected to a second electrode ( 26 ) which is in turn connected to a second potential ( 15 ) having an opposite polarity to that of a first potential ( 14 ) connecting the first electrodes.
