Изобретение позволяет повысить производительность процесса избирательного нанесения активатора по рисунку схемы печатной платы и получить оптимальный по толщине слой каталитически активной меди после термолиза при аддитивном методе изготовления печатных плат. На заготовку печатной платы наносят негативный оттиск рисунка печатной схемы посредством гальваностойкого материала, который не смачивается активатором, и образовавшиеся канавки на месте проводников заполняют активатором с определенной концентрацией активных компонентов валиком из пористого материала до определенного уровня, затем производят термолиз активатора, наращивание меди на проводящий рисунок и удаление гальваностойкого материала с пробельных мест печатной платы.The invention allows to improve the performance of the process of selective application of the activator according to the printed circuit board pattern and to obtain the optimum thickness of catalytically active copper after thermolysis with an additive method of manufacturing printed circuit boards. A negative print of the printed circuit pattern is applied to the printed circuit board by means of galvanically resistant material that is not wetted by the activator, and the resulting grooves at the site of the conductors are filled with an activator with a certain concentration of active components with a roller of a porous material to a certain level, then the thermolysis of the activator is performed, the copper is expanded onto the conductive pattern and removing galvan-resistant material from the gaps of the printed circuit board.
