  • Patent number: 10806029
    Abstract: A catalytic resin is formed by mixing a resin and either homogeneous or heterogeneous catalytic particles, the resin infused into a woven glass fabric to form an A-stage pre-preg, the A-stage pre-preg cured into a B-stage pre-preg, thereafter held in a vacuum and between pressure plates at a gel point temperature for a duration of time sufficient for the catalytic particles to migrate away from the resin rich surfaces of the pre-preg, thereby forming a C-stage pre-preg after cooling. The C-stage pre-preg subsequently has trenches formed by removing the resin rich surface, the trenches extending into the depth of the catalytic particles, optionally including drilled holes to form vias, and the C-stage pre-preg with trenches and holes placed in an electroless bath, whereby traces form in the trenches and holes where the surface of the cured pre-preg has been removed.
