Yes! I'd never seen that before in the hobbyist sphere and suddenly I don't hate SMDs.

Most board vendors can sell you the stencil for your PCB for very cheap

Yes, I thought this was pretty common now. I do it every time as it hardly adds any cost.

It’s also worth looking at the costs for SMT assembly. Companies like JLC are amazingly cheap for fully assembled boards (provided you stick to their standard parts catalog).

I was almost going to do that for one of my projects, I got my design right on time for chip crisis to start....

But yeah, even for something like 10 boards the prices for assembly has become pretty reasonable, especially if you design for the parts they have in stock.

I consider soldering the board a bit too far on the externalize my hobby side. I like soldering those !

The "screen" he's using in the video is called a stencil. They're made out out of thin stainless steel. These days they're pretty easy to come by even for the hobbyist.[0]
