Does anyone have any experience with "Buried Capacitance" materials for p.c. boards? Since I do alot of EMI/EMC control on products at the p.c. board construction level. I'd like any input about this stuff from the FIELD. The Zycon Corp. calls it ZBC-2000. I am NOT advertising this product. Assume my frequency ranges out to 30 GHz. Doug McKean, [log in to unmask]
