[SI-LIST] Re: New Buried Capacitance Material

Fred,

That's a new material with no track record.  Sounds pretty attractive, but may
haver lots of risks.  When you use such a new material, you ar playing bet the
product on something new and untried.

I'd be very careful if I were you.

On the plane capacitance front, I've never found a time when I needed ZBC or any
other special form of buried capacitance.  Careful arrangement of the power
planes in your PCB nearly always does it.  When that is not enough, I fill
unused spaces in signal layers.

Good Luck.
