Props to Ohararp for the idea of using kapton film instead of mylar. If you need stencils cut, because, say you don’t own a laser cutter, you should contact him!
The 2mil kapton/polyamide film was purchased from McMaster-Carr part #2271K2 for about $12/sqft. For a 35W Epilog laser, I used 100 speed, 15 power, 500 frequency to get a reasonably clean cut. The PCB holder is cut from everyday 1/16″ acrylic. Solder paste is from digikey, part# KE1507, you’ll want the nice rounded plunger from McMaster, part #66045A13 and ~22AWG needles such as #75165A682. While you’re at it, you’ll probably want to pick up a bottle of de-leading soap from Mcmaster, part # 7724T24
