Mylar Reflow Stencils M y l a r R e f l o w S t e n c i l s

Solder paste stencils let you put down neat, even paste on a board full of tiny surface mount pads before it goes into reflow. I wanted a fast, reliable way to make them myself, so I worked out an in-house process for cutting them from Mylar on a laser cutter.

It produces precise, fine-pitch SMD stencils with sub-millimeter accuracy, and each one takes about ten minutes and less than ten cents to make.

I cut the stencils from Mylar because it’s cheap and the laser cuts it cleanly. That’s what keeps each stencil under ten cents, and because they’re made in-house, I don’t wait on an order before a board can go into reflow.
