I have a customer who has asked me if I know about shielding vias.
I don't know much about these. All I know is that the size of the PTH
and the distance apart are based, somehow, on what frequency the
logic (PCB) is operating at. (Yessss?)
Now I don't have IEEE text books anywhere near this facility.
I'm a simple fabricator. Can someone who's savvy with RF <or even
Microwave> design give me some pointers to what kind of formulas are
used to determine this shield via barrier technique.
Thanks in advance for any and all replies.
