In addition to the other advice already given, also consider the use of
machine pin IC sockets - Augat & Assman come to mind. Their design allows
easy soldering of top side connections.
I will often add a short stub 0.062" wide to the outside edge of all
top-side IC pin connections - these serve as a marker to ensure that I
don't miss a top-side connection on a socket as well as providing just a
little more surface area for easier soldering. That width of 0.062" is the
width of the IC pads.
One of my techs had another trick that is often useful - he would go into
the plot files for the board in question and manually delete any top-side
pads that had no connection. I'm not quite sure how he determined just
what to delete (it's just a file full of numbers) but however he did it, it
was remarkably effective in ensuring that all top-side connections were made.
