  • Publication number: 20200008306
    Abstract: A circuit board is formed from a non-catalytic laminate coated with an optically curable catalytic adhesive, which, after curing with an optical source such as UV, has a resin rich surface with catalytic particles dispersed below a surface exclusion depth. The catalytic laminate is subjected to a drilling and blanket surface plasma etch operation to expose the catalytic particles, followed by an electroless plating operation which deposits a thin layer of conductive material on the surface. A photo-masking step follows to define circuit traces, after which an electro-plating deposition occurs, followed by a resist strip operation and a quick etch to remove electroless copper which was previously covered by photoresist.
