Buried capacitance is like a layer of capacitors.
Most notable developer was Zycon (I think) which was bought by HADCO Corp.
(a PCB fabricator).
Allows you to remove caps from your board. I was lucky enough to assist in a
test on an existing board. We removed all the bypass caps and left just the
bulk caps and inital caps where the power came in the board. Our engineers
found no noticable difference between the old and new board.

Hi TN,

I recently get the words "buried  from  document. What does
it mean? What's its quality requirement? How can I start to produce the
PCB with buried capacitance? Is there any technical reference document?
I shall be very appreciated if you can give me more help.
Regards,
