DJ,
thanks a lot.
That sounds interesting, does this work for a 12-Lead Plastic MSOP,
Exposed Die Pad which has "conventional pins" (the exposed die may be up
to 10 mil above the board) as well?
One option for me may be to change to a DFN package where all pins are
under the IC in one plane. I choose the MSOP to only have 1 problem
(exposed pad only), not 13 (for all of the pins, including the exposed
pad), but now I think it was the wrong decision. It's easier to deal
with 13 similiar problems compared to 1 big problem.
