how many vias for copper area
Hi all,
On few RF evalution board I have found exposed copper areas (without solder mask) on top side. For what purpose it might have been put for?
Also found a guide line that "use a large number of vias to tie the front and backside ground plane regions together." How it will help the design( since the via will add indectance to the plane)?
Thank you.
