PRODUCTION OF PRINTING MASTER PLATE OR PRINTED CIRCUIT BOARD

摘要

An improved apparatus and process are described in which metal images are transferred to a softenable receiving layer (32) using commercially available multi-stylus recording heads (10). The transfer medium is comprised of a resistive layer (16) and a thin metal layer (14) thereon. Electrical currents are provided by the recording styli (18) of the multi-stylus recording head. Localized electrical currents in the resistive layer (16) provide sufficient heat in the metal layer (14) to soften regions of a meltable receiving layer (32) when it is brought into contact with said heated metal layer. Metal imaging for use in printed circuit board manufacture and in formation of printing masters can be transferred by this technique.
