Laser Cut Stencils | 25 March, 1999

We make an excellent chem-etch stencil. Our customers have had success printing 16 mil pitch without a problem. This is not an advertisement!

When we try to sell our product to new customers, we find more and more people willing to pay more for the laser cut stencils and not interested in even sampling the chem-etch. Why?

I'd like to hear from some users of laser cut stencils and the rational that led you to laser cut stencils over chem-etch. Are the results actually better or is it the latest industry fad?

B: Are you electropolishing your apertures? With a finish of this type you can come close to Laser cut's smoothness.

Re: Laser Cut Stencils | 1 April, 1999

Dan, The rationale to use laser cut stencils in my experience is based on the benefits to paste release. Laser cut stencils are "supposed" to have a smoother inner aperture wall. That, combined with the trapezoidal shape (which can be emulated with a chem etched stencil) of the aperture and electropolishing is supposed to promote greater release. In reality, a well manufactured chem etched stencil can go toe to toe with a laser cut stencil when it comes to paste release. The true upside to a laser cut stencil is more latitude when it comes to aperture size vs. plate thickness which minimizes many stencil design related issues. | B: Are you electropolishing your apertures?

(I'm alway the sucker in the audience of a presentation that asks the questions that pave the way for the presenter.) ;-)

So why don't you post-up some statistics, pictures, and what not that demonstrate the superiority of your product? Where can we review studies, published by third parties, supporting your claims? Tell us, how does your pricing compare with other stencil products? How do your turns match-up with your competitors?

Re: Laser Cut Stencils | 19 November, 1999

Laser cut offers the following two major advantages... the aperture tolerance is much better and the trapezoidal apertures are more consistant. For the small difference in price, you get the assurance of < 1/4 mil tolerance on aperture size. However, all these advantages are mute if you don't have the stencil electropolished. Laser cut does NOT produce a smother aperture wall. In reality, the walls are less smooth. Mark
