When I'm trying to be fast to build, I use my butane soldering iron with the hot air tip and I put a high wattage tip on my soldering iron.
I hold the two of them so the hot air is preheating the next pin(s), I put the board in the pana vise and hold the solder with my left hand. Like this, I can solder about as fast as I can push the solder in. A 40 pin socket takes 10 seconds. Of course, I have all the parts already tacked in place with 2 opposite pins soldered. What ever you do, don't stop on a pin! I suggest practicing on scrapped boards before trying it.

I'd like to get it built to officially kick off my "new build" S-100 system, but I am having flashbacks to the 12 x 96-pin ECB backplane I made (1152 pins vs 1800) and thinking about how long it will take. The pins are spaced out more than the DIN connectors but there are so many of them...
I am considering an alternate approach based on a technique called "pin in paste" used for soldering through hole components in industry, as shown in this video - https://www.youtube.com/watch?v=UlktpQvqxtE The idea would be: -Using a squeegee, "load" paste into 2-3 connectors worth of holes until it is sticking just a little bit out the other side, like in the video -Insert connectors and use bolts to hold in place. Solder paste gets push out on the pins like in the video. -Using a Hot Air Rework station set at the appropriate reflow temperature for the solder paste, go down each row of pins and reflow the solder into the joints. My feeling is that using this method I would be able to complete 2-3 connectors in say 15 minutes and the entire board in like 1.5 hours vs many hours by hand. Thoughts? Crazy idea?
