Making the stencil
We managed to produce our own stencils for applying the solder paste using a low-cost laser engraving module. The Creality Ender S1 is a bery suitable 3d-printer and for 80USD extra you can get the laser engraving module. It's a but tricky to find the right settings, speed and strenght etc, to make precise stencil, focus calibration and color and property of the paper, each time you will have to fiddle the settings for optimal results.
Preparing for reflow
Preparing a simple setup. Just tape things down and fix the PCB
Precisely position the stencil and tape it down in place
Add some solder paste, Mechanik seems to be the brand of choice
Use a some kinda rakel and smear it onto the pads
Reflowing on small Hotplate
Check how nicely the paste was applied. if bad, just clean it and try again
Now start placing the parts with a fine tweezer
Don't worry too much if they are not perfeclty positioned... it will work miraculously!
Put it on the hotplate and start heating
Watch the process self-aligning and soldering all the parts
There you go, DONE!
