Abstract

See full text

A method is provided for fabricating a terminal electrode. The terminal electrode is applied on a multilayer ceramic capacitor (MLCC). The method prints inner electrodes on full area together with protective layers. The MLCC uses the thickness of thinned dielectric ceramic layers and the stacking of nickel inner-electrode layers. High capacitance is achieved at ends and sides with high electrode-to-ceramic ratios. Thus, the present invention uses a coating technology of ultra-low-temperature electrochemical deposition to fabricate low internal-stress MLCC terminal electrodes together with insulating protective layers for improving MLCC yield while cost reduced.
