I am having a problem with the RF engineer saying the board material
(vendor) is the problem with his circuit not working. In every formula I
have looked at the dielectric constant of FR4 is the same.
My boards are .062 thick FR4 Tg 130. no soldermask no silkscreen.
Can someone out there explain to me what the differences can be between two
vendors when they are both using the same process notes I supply to make the
boards??
And how this might effect the RF circuit?
Thank You
