I think that eventually we will be soldering to both sides. The size of the
board is PC/104 compatible which is about 3.5" x 3.75". The ic types are
soic versions of HCMOS 74XXX series devices with a smattering of PLCC 's and
QFP's. The smallest pin spacings on the chips we will use is 25 mils.
Thank you
Keith Causey.
