Abstract:
A method of fabricating a printed circuit board having capacitance components, including: providing a core board having first and second surfaces with first and second wiring layers provided thereon, respectively, and electrically connected, a second dielectric layer, and a carrier board sequentially provided thereon with a second metal layer, a high dielectric material layer, and a third wiring layer with a plurality of first electrode plates thereon; laminating the core board, second dielectric layer, and carrier board to one another; removing the carrier board so as to expose the second metal layer; and patterning the second metal layer so as to form a fifth wiring layer having a plurality of second electrode plates and a plurality of second conductive vias electrically connected to the third wiring layer, thereby allowing the first electrode plates, high dielectric material layer, and second electrode plates together to form a plurality of capacitance components.
