Hello everybody,
I am planning to use FR4 compatible buried capacitance (BC) laminates for
power planes in a high speed board. I have come to know about the
following materials:
1. BC2000 (Hadco)
2. BC1000 (Hadco)
3. EmCAP (Hadco)
4. C-Ply (3M)
5. HiK (Dupont)
Except BC2000, I could not get much details about these materials. I have
the following questions:
Q1: Are all of them FR4 compatible? (I know that BC2000 is FR4
compatible.)
Q2: How much costly are these materials?
Q3: What precautions do I have to take in the layout of the board when
using these materials?
Q4: What are the other BC materials available?
Thanks,
