The development of novel composites is ongoing in an effort to develop materials with an energy density greater than 5 J/cm3 for use in high voltage capacitors. The materials are composites initially developed to reduce the size of high power antennas. Due to their combination of a high dielectric constant and high dielectric strength, some of the original composites were directly transitioned for...
In this study, the polymer/ceramic composites with high dielectric constant (HK=20 substrate) were prepared to investigate the temperature effects on electrical properties. The material properties of HK substrate were compared with those of FR4 substrate and MLCC-NPO capacitor device. Curie temperature of the HK substrate could be obtained from the curves of current densities varied with temperatures...
Epoxy/ceramic composites are one of promising materials as embedded capacitors for a SiP technology, because they have a good processability and a compatibility with printed circuit boards (PCBs), in addition to a high dielectric constant. In this study, we have fabricated embedded capacitors in PCBs using epoxy/BaTiO3 ECFs, and evaluated their reliability at high temperature aging after moisture...
Embedded capacitor technology is an essential method for miniaturization and high performance of electronic package systems. High dielectric constant epoxy/ceramic composites have been of great interest as embedded capacitor materials for MCM-L applications, because they have good processability and compatibility with printed wiring boards (PWB), in addition to high dielectric constant. In previous...
Epoxy/BaTiO3 composite embedded capacitor films (ECFs) were newly designed for high dielectric constant and low tolerance (less than plusmn5%) embedded capacitor fabrication for organic substrates. In terms of material formulation, ECFs are composed of specially formulated epoxy resin and latent curing agent, and in terms of coating process, a comma roll coating method is used for uniform film thickness...

We report a novel polymer-ceramic composite of high dielectric constant for embedded capacitor application. The low cost polymeric matrix was benzoxazine resin and the high constant ceramic filler for the polymer composite was BaTiO3. The benzoxazine/BaTiO3 composite was prepared by the method of mixing. The dielectric constant, dissipation factor, volume resistivity and breakdown voltage of the...
