Thank you for taking the time to respond.
Boy, it sure is difficult to keep up these days,
one guy says one thing, another says the opposite.
So, is there NO advantage to reducing the material between planes?

onward thru the fog,
Jack

                Jack,

                Brooks wrote recently about planes acting as caps - they do
not

                Much as we don't like them, every single power pin MUST be
bypassed by 0.1uF
                caps - if a large chip like a BGA or PLCC has say 4 power
pins - bypass them ALL
                or pay the piper.
