Yes, the aspirin trick is a great one on the enameled wire! I think of this place every time I use it.
I've built many circuit cards on Vector #3677 plugboards. They are about 4.5 inch x 9.5 inch, and they have a 22/44 edge connector, and a hole pattern for 3 columns of ics. I use #30 ga wirewrap wire as soldered jumpers. I run the jumpers on the top side, leaving the solder side being just the solder joints. One really nice advantage of the Kynar insulation is that it has a very small amount of "shrink-back" when soldered. I have found that many other wires such as stranded wires from ribbon cable tend to have lots of shrink-back, which can be a real pain. I also tend to juice up most of my solder joints with a little extra flux to make the solder flow easily. I use some special non-conductive flux for these boards with the tiny close-spaced traces. Yeah, they are through-hole parts, and that stuff is plenty small enough for me! I have not worked on SMD yet, and do not especially relish the thought of it.
