Abstract
A process for fabricating a circuit board uses a catalytic dielectric core having catalytic particles, a foil top surface, and a thin foil bottom surface with a foil backing of sufficient thickness to absorb heat from a laser drilling operation to prevent the penetration of the thin foil bottom surface during laser drilling. A sequence of steps including a laser drilling step, removing the foil backing step, electroless plating step, patterned resist step, electroplating step, resist strip step, tin plate step, and copper etch step are performed, which provide dot vias of fine linewidth and resolution.
