Abstract:
A process for making a circuit board modifies a catalytic laminate having a resin rich surface with catalytic particles dispersed below a surface exclusion depth. The catalytic laminate is subjected to a drilling and resin-rich surface removal 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.
