I just stumbled upon this amazing resource -- the NASA Workmanship Standards Pictorial Reference -- courtesy of NASA and the US Taxpayers!
For anyone putting together their electronics, this is a great reference for answering the "how do I put this together" questions that inevitably comes up when assembling printer kits!
The document does not provide the explicit "how to" steps, but you can learn a lot just by looking at the desired end-results.
If you want to check out the various standards (including the standards that apply to this pictorial reference), check out the NASA Technical Standards Program page.
