These are low cost SMT Stencils made out of Mylar or Kapton, used mainly by students and hobbyists to assemble prototype printed circuit boards. We use state-of-the-art UV laser technology to produce smooth aperture walls resulting in excellent print performance.
With our UV laser technology we create your custom stencil with a thickness of 0.003" or 0.004", offering the best precision cut you can find in the market..
Pricing: $50.00 for the first 25 square inches, $1.85 for each additional square inch.
Mylar is a polyester film made from stretched polyethylene terephthalate which allows to make great prototype stencils because of its high tensile strength. Kapton is a polyimide film produced from the condensation of pyromellitic dianhydride and oxydiphenylamine, which not only offers higher tensile strength and reliability than Mylar but has the ability to maintain its excellent physical, electrical, and mechanical properties over a wide temperature range.
The main difference between Mylar and Kapton is that Kapton can remain stable in a wide range of temperatures, from -273 to +400 °C (- 459 to + 752 °F)
while Mylar's range is about -70 to +180 ºC (-94 to + 392 ºF), this allows Kapton to be one of the most used materials in flexible printed circuits.
In 2003, Stencils Unlimited introduced the process using Prototype SMT stencils with a Toaster Reflow Oven to assemble prototype PCBs. The same process can be used with Mylar & Kapton SMT stencils. We are backing that with a money-back guarantee program. Buy a low cost Mylar & Kapton SMT stencil and try it using our recommended process. If you are not satisfied with the results, you may return the stencil for a complete refund.
