The brochure discusses methods of chemical-electrolytic metallization of various dielectric materials. The compositions of solutions for chemical metallization by copper plating and nickel plating are given, as well as the properties and scope of coatings on plastics and inorganic materials. Information on the production of printed circuit boards based on the processes of metallization of dielectric materials is presented. The brochure is designed for workers, laboratory assistants and foremen of galvanic shops. It can also be useful to the technologists of galvanic shops.
