I assume you're looking at stencil fab equipment because you need 'faster turns' than you can get from available stencil suppliers. While you're assessing this, consider other alternatives, such as: * Dispensing paste. [A very funny SMTNetter, livin

I figure if you need the rest, you don't need these. These strips are from some laser cutting tool fabricator. They give them to their customers [laser cut stencil fabricators] so the customer can do a good job. Yall have a nice day now, y'hear?

Try .005 or even .004 thick laser cut electopolish stencil and reduce grain size of paste. Go with 400 or 25 in the case of AIM. We had a similar prob.
