  • Method for manufacturing a laminated layered printed wiring board using a sulfuroxy acid and an oxiding treatment of the metallic wiring patterns to insure the integrity of the laminate product
    Patent number: 4702793
    Abstract: A sulfuroxy acid reducing agent composition can be used to treat the metallic conductive pathways formed in or on the surface of printed wiring boards in order to assure that the copper pathways are firmly and securely bonded to laminate layers of layered printed wiring board articles. The sulfuroxy acid reducing agent treatment promotes the rapid formation of a uniform metal oxide layer on the printed wiring board conductive pathways, when the printed circuit boards are exposed to an oxiding agent, which insures that the compositions used in forming the printed wiring board laminates do not interact with the active copper metal preventing delamination.
