I posted these on someone's build thread a while ago as kind of an afterthought. It was really helpful in making me more confident with a soldering station. So I thought I'd make it its own thread for future reference. I deleted the extraneous information from the NASA manual and just got to the good stuff in chapters 9-10. This is a visual reference card for acceptable soldering standards: https://workmanship.nasa.gov/lib/insp/2 books/links/sections/601 General Requirements.html Also, this guy is great to watch. Of course he knows his stuff, he's wearing a lab coat. This stuff helped me. Hope it helps others too.
