I'm working on a layout with two quad flat packs. A
substantial number of pins on each chip have no
connection. Because of the difficulty of
hand-soldering to fine pitch pins, I would like to add
a track and a via to each unused pin for possible use
later.
I'm have two issues:

Another solution, besides those already given, is to use, in the footprint,
through pads the size of vias and with the same hole size, given the same
net as the SM pad. You will have complete DRC protection
Another solution which might be better in some ways is to add a test point

2) a single pad, multilayer, round 32/62mil
great for the scope probe to
