I am interested in comments on layout/design and if the approach
is bad good etc. and well anything you experienced people can
offer an amateur hobbyist like myself.

top is red
bottom green

round dip pin through pads are .075" (.029" hole)
round through via pads are .056" (.020" hole)
square pads bottom .65" x .010"
plcc pads are standard smt



I'll second John's and Rich's comments. Besides rounding you might want
to consider flaring the traces into the pin header vias. I think
layouters call that "drop". That way there could be less stress fractures.

Also, put unconnected copper markers at the four corners and mark where
pin 1 goes. Helps with alignment. Especially when tired it can easily
happen that a chip is plopped onto it the wrong way (usually followed by
a major expletive).

Oh, and add your name, logo, whatever and if you want to be extra good a
part number for this board plus a blank assembly number field large
enough to write on with a Sharpie.
