Abstract
A device includes a ceramic substrate. A ceramic via is defined within the ceramic substrate at an actual location which differs from a designed desired location for the ceramic via. A minimal capture pad electrically communicates the actual location with the designed desired location. The minimal capture pad contains a ceramic via contact portion, a thin film stud contact portion, and a connecting portion; and each of the three is configured to be as small as permitted to limit the capacitances produced by the capture pad.
