In the tutorial: https://learn.adafruit.com/smt-manufact ... t-stencils
the solder pads are shrunk by 2 mil (2 thousandths of an inch = 0.05mm).
Does that imply that the Adafruit lasercutter has an effective beam width of 4 mil when cutting this material (Kapton film)?
Which lasercutter do you use? With what tech specs?
Anything you can say about how to achieve a nice narrow beam width?
I'm really motivated to get this to work because IMHO applying solder paste by hand is the WORST task in a SMT PCB job!

Re: Laser Stencil Tutorial - laser beam characteristics
Thanks.
In the tutorial you use 2 mil Kapton film.
Reading around, solder paste stencils seem to be thicker than that: upwards of 5 mil.
Any comments?
