An investigation determined that thick film feedthroughs could successfully be printed with 12-mil holes in 20-mil square pads, 10-mil holes in 15-mil square pads, 6 {times} 12-mil oval-shaped holes in 10 {times} 35-mil rectangular pads, and 6 {times} 9-mil oval-shaped holes in 10 {times} 25-mil rectangular pads. The results were verified by printing test vehicles containing the four feedthrough configurations, electrically testing the feedthroughs for continuity, and cross-sectioning each of the feedthroughs in two axes
