Abstract
Embedded capacitance materials (ECMs) are gradually taking the place of traditional discrete capacitors in the fabrication of high-end electronic devices. However, the exploration of suspensions with simple compositions and improved performance remains an important topic for the further development of ECMs. In this work, commonly used auxiliaries are not employed, and ethanol is added to a BaTiO3/epoxy resin ethyl acetate suspension, which improves the film-forming ability. The corresponding ECMs show increased mechanical and electrical performance due to the better dispersion of the BaTiO3 nanoparticles. The fabricated embedded capacitors have low tolerances and can pass reliability tests, which verifies their applicability in printed circuit board manufacturing.
