Abstract
We developed a novel method for recycling wiring polymer boards using a layer-by-layer multilayer of colloidal SiO2 particles as a separation layer on a PET substrate. A plating-promotion layer of poly(4-vinyl pyridine-co-1-dodecyl-4-vinylpyridinium bromide)(QP4VP) was adsorbed on the colloidal SiO2 multilayer and patterned by vacuum ultraviolet light irradiation through a photomask. Selective Cu deposition occurred in accordance with the QP4VP photopattern shape and Cu wiring boards could be prepared. The Cu wiring boards were separated readily due to dissolving SiO2 particle by an alkali NaOH solution. It was found that the colloidal SiO2 multilayer was available for the separation layer of wiring boards.
