Most likely induction would heat the wrong parts if any.

Hi Demian,

I don't know which way this method would go, but I can only assume that if it does heat the components and PCB, it will be fairly destructive to the parts and PCB. That could be a lot of fun too!

Anyone want to try the microwave?
Don't! I already know how destructive this is to anything conductive.

AFAK the board and components are heated to the same temperature in a large convection oven.

Love the microwave idea. Wish I were wealthy enough to try it.

Of course this a all lot hot air.

I thought the soldering was excellent on the sample I got from you.
That was by a company 😊...

I purchased one of those controlled-heating-curve ovens, similar to the Elektor one.

Used it a few times but the stuff with the stencil and paste got quite messy. Probably my incompetence.

Switched to just soldering them by hand, never looked back

YMMV

That is really the issue for me with DIY projects.... time. anything slowing me down, I dont do... plenty of other things to do. Then secondary things - like I cant read the value on the various smd parts, slows me down also. etc etc.

From what I've seen one of the better ways of putting down small batch pcb solder paste is with a pneumatic dispenser, which usually has a pick and place suction function as well, together with a rolling table for resting your arm and moving across left to right with the pcb boards laid out in a grid, but unless you're working on a batch of, say, 4-5 or more pcb's, might as well hand solder...

Having some experience of screen printing from back in the day, I would observe that there is the same set up time and cleaning whether doing one impression or twenty and unless the solder stencil can be stretched on a frame like a silk screen, would expect solder stencilling to be a messy experience, imho...
