Disclosed herein are a printed circuit board with embedded capacitors
therein and a process for manufacturing the printed circuit board. The
embedded capacitors are formed by applying a photosensitive insulating
resin to a printed circuit board inner layer, and applying a high
dielectric polymer capacitor paste thereto. The process for manufacturing
a printed circuit board with embedded capacitors therein comprises the
steps of: i) laminating photo resist dry films to a copper clad FR-4,
exposing to light and developing the dry films, and etching copper foils
of the copper clad FR-4 to form bottom electrodes for forming capacitors;
ii) applying a photosensitive insulating resin to the surfaces of the
bottom electrodes, and exposing to light and developing to etch the
photosensitive insulating resin; iii) applying a capacitor paste to the
etched regions and curing the capacitor paste; iv) plating the upper
regions of the cured capacitor paste and the photosensitive insulating
resin using an electroless copper plating process to form copper foil
layers for top electrodes; v) laminating photosensitive dry films to the
copper foil layers for top electrodes, and exposing to light and
developing the photosensitive dry films to etch regions of the dry films
except for the copper foil layers where the top electrodes are to be
formed; and vi) etching the regions of the dry films except for the
copper foil layers where the top electrodes are to be formed, and the dry
films formed on the top electrodes are removed so that the capacitor
paste is discretely positioned between the top electrodes and the bottom
electrodes to form discrete capacitors.
