Patent ID: 7359213

Claim:
A circuit board comprising: a first single layer dielectric laminate material sheet having preformed thereon contact traces on first and second surfaces of the single layer dielectric laminate material sheet and vias extending into via-in-pad contact pads on the first surface of the single layer dielectric laminate material sheet; at least one passive component mounted on the via-in-pad contact pads preformed on the first surface of the first single layer dielectric laminate material sheet; interconnections formed from the passive components to the contact traces of the first single layer dielectric laminate material sheet by the vias extending into the via-in-pad contact pads; and a second laminate material sheet laminated to the first surface of the first single layer dielectric laminate material sheet and having at least one of a recess, a through-hole or both formed therein for accommodating the passive component; wherein a dielectric material laminating the first and second laminate material sheets to each other embeds at least a portion of the passive component; and wherein a second surface of the first single layer dielectric laminate material sheet on which the contact traces are formed is exposed as a mounting surface of the circuit board for mounting an active component.
