User:Asj/Notes about laser cutting solder stencils

Most pads are ok - perhaps a bit large.

Small pitch QFN packages are a problem. To do these,

• For each QFN pad, downsize "solder paste absolute clearance" to -0.09 and produce solder mask svg
• Configure Light burn to engrave at
  • 100mm/s at 28%
  • Line interval of 0.02mm

It might also be a good idea to apply this globally since other pads also end up a bit large. This can be done:

• File -> Board Setup -> Solder Mask Paste
• "Solder paste absolute clearance" -> -0.09mm
