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.
