Laser cutter for PCB stencils?

[smdfan]

Hi there,

I am planning to buy a small laser cutter. I want to use this laser cutter/engraver to cut plastic/mylar sheets. These sheets of plastics are of standard size (8.5x11 inch) and they have a thickness of 1-4 mil (0.03-0.10mm).
I want to use these sheets of plastics for stencils to be used for printed circuit boards.

I have looked at some Chinese and this one looks fine to me. (See link below):

this one also looks good:

Do you have any suggestion, and advice? I have never worked with lasers before. I need the cuts to be very precise, clean, and not burned.
The stencils I want to make are similar to the one in this link:

Those units are similar to the unit I have:

I paid less than $1500 shipped to the door for this unit and have been happy with the results.

It came with a 2" FL lens which produces a pretty small spot size, should be acceptable for your application. I would check with the seller to be sure.

Zax.
