I make and sell low voltage, mostly digital, retrocomputing expansion boards as a hobby/hustle. I use all through-hole components partly because of the retro aesthetic and partly because I find soldering through-hole relaxing and fun to do.
I'm selling enough boards now that I'm feeling like my assembly and soldering process should be optimized. One of the boards has about 30 components on it and if I'm making 10 of them, it can take up a whole Saturday afternoon.
Currently I place a part, flip the board in my hand while holding the part, tack one of its pins with the iron while making sure the part is fully inserted and aligned if necessary, lay the board down and solder the rest of the pins, then move on to the next part. I am pretty sure this isn't the best way to do this.
Do you have any tips or tool recommendations to help me optimize my board assembly / through-hole soldering process?
