Abstract
Provided herein are devices comprising a printed wiring board that comprise, singulated capacitors fabricated from known good, thin-film, fired-on-foil capacitors. Provided are methods of incorporating the singulated capacitors into the build-up layers of a printed wiring board to minimize impedance. The singulated capacitors have a pitch that allows each power and ground terminal of an IC to be directly connected to a power and ground electrode, respectively, of its own singulated capacitor. Using a feedstock of known good, fired-on-foil capacitors allows for improved PWB yield.
