Does anybody have any tips on cutting Mylar (2 or 5 mil) with a CO2 laser? I'm trying to make stencils for putting solder paste on circuit boards. The holes are fairly small and when I try cutting the edges get all melty. There seem to be lots of other folks out there doing just what I'm trying to do so I'm sure there's some trick that I'm missing. Is it maybe because I don't have air assist?
Thanks,
Scott
