Hi All,
I am writing to ask what is the IPC tolerance for how flat a PCB must be
and what callout should I use in my Fab Notes? This PCB is going to be
part of an RF Filter module that will be SMD. I made an inquiry a few
weeks ago about best practices to employ for designing a flat board that
has a 25mil 6010 top core and 2 FR-4 cores for control routing.
Thank-you all again for the great timely advice on that question, now
I'm just trying to make sure the Fab house and I are on the same page.
