I’ll have to try that. I wonder if solder paste might work the the same effect???..dispense paste from a needle to both sides, and heat one side.
I made a video of my method which uses paste once, but it’s too blurry to be useful. I’ve explained this a few times, but for some reason nobody has bothered to try it. It does need paste and a hot air station, though.
I have a wooden desk. The vias are drilled so that my 22ga wire fits in snuggly. I lay the PCB flat on the desk and insert the wire into a via and cut it off flush with PCB using side cutters. I can step through all the vias like this. So at the end, all the vias will have a small piece of wire in them. I use the syringe to put a dab of paste on each via then hit it all with hot air. After that I put it in a clip and flip it over. Paste the other side and hit it with hot air again. It’s pretty quick. You need to do all the via’s first and it takes a bit of experimentation to get it working all the time.
