Besides the enviable expansion coefficient and thermal properties, the provided ceramic steatite high alumina products function at different working temperatures, making a smaller package size. These products deliver ideal high-frequency performance as well as can be available in hermetic packages for zero water retention. Using our products also ensue in a lower complete system cost and cost-effective for thick packages, since the customers have parallel layers processing. Our ceramic steatite high alumina products are normally composed of metal cores. For elevated thermal conductivity, aluminum nitride is ideal, offering higher 150 w/mK. All models of our products will give ideal thermal performance than steel core boards, as there is zero demand for an electric layer among the circuits and the core.
