Not perfectly SI-related but I figured there are enough PCB manufacturing
experts around on this list to warrant a question:
What are good materials for low-leakage, high-voltage (2-10kV) applications?
The standard solution here has been to use Rogers material (not for SI - the
application is very slow speed, a few MHz at best - but purely for leakage
reasons), but of course this is an expensive approach. Can anybody recommend a
less pricey material that nevertheless offers very low leakage and doesn't have
issues with moisture absorption (like FR-4 has)? The boards are multi-layer
(typically 6-10 layers).
Thanks in advance,
Wolfgang
