Just a bullet! My results are, .005" stencil thickness should measure between .0055" - .006" if your pressure is correct, metal blades and snap-off is set up correctly. Do you have aperture reductions at the QFP locations "typicial industry standard

I've been using metal blades on several brands of printers over the past few years and have to agree with comments in other replies. Contact print is a must or you will tear slits in your stencils at the ends of the blade. Center-mounted (floating) s

Viewing a blade on its own merits may give you subjective results. Are you asking about metal or rubber squeegees? You really need to examine the print quality before you decide if a blade is worth using. If you are getting the right paste deposit vo

The obvious is size. Besides that, it depends on your screen printer. Some "smart heads" need to be retaught with the metal blades for each board. Some need to have the set-up programmed changed too. Angle of attack is something to double check a

metal blades scraping against a metal foil; do it enough times and any stencil will look like that. It's possible the squeegee pressure is set too high, exacerbating the condition. Try reducing squeegee pressure a little at a time, making sure you
