    Abstract: The invention relates to an apparatus and method for improving AC coupling between adjacent signal traces and between plane splits and signals spanning plane splits on circuit boards. A circuit board includes adjacent conductive means and an oxide means interposed there between. The oxide means is a copper oxide, e.g., cupric or cuprous oxide. In one embodiment, the adjacent conductive means are adjacent voltage reference planes with a split interposed between the conductive means. The copper oxide fills the split. In another embodiment, the adjacent conductive means are differential signal traces. The copper oxide fills a gap between the differential signal traces. The copper oxide is a non-conductive material with an increased dielectric constant as compared to other common dielectric materials used as fillers. The increased dielectric constant increases capacitance, in turn, increasing AC coupling.
