Kenny: Since you need to use water soluable flux and can't use no-clean, consider asking your board fabricator to plug the via.

What does "maintain it really good" entail? For reference, this is our maintenance procedure for the FX-D: - At the end of an 8hr shift, the solder paste path is purged start-to-finish using Nordson's ValvePurge. The machine's then powered down and

Similar to Jax's comment, concern yourself with the the activity level of the flux. A more active flux would be more aggressive in removing tarnish. Certainly, the choice depends on the type and amount of tarnish. Probably, you need to consider your

Does anyone have an equipment recommendation for stencil cleaner brand/type that they would recommend for no-clean pastes? I have used ultrasonic cleaners in the past with aqueous pastes, but I don't want to buy something that really won't work for u

You can stop cleaning after a job when there is no more paste in the apertures. Under wiping should be done with a quality cloth and should leave no paste on the underside of the stencil (assures good contact on the next print and reduces chances of

There are a lot of things that might affect your cleaning efficiency. Paste type (no clean or w/s?), cleaning chemistry, aperture aspect ratio (aperture width/stencil thickness), "linty" wipes, etc. Another thing you need to look at is the frequency
