Normally, we try to limit the over print of the paste to the width of the pad on both sides. If you are using 500um pad, then I wouldn't try over a 1500um aperture. Mario Scalzo, CSMTPE, Dartmouth 6 Sigma Green Belt Technical Support Engineer - Ind

Hi Pavel, We regularly use over printing on a multitude of problem parts including fine pitch QFP's. In an Automotive Environment the only thing you can change without a mountain of paperwork is the stencil. best way to work out how much you can get

Successful solder paste overprint is a function of the solder paste rheology, solder mask and through hole component stand off. * Solder mask with a high surface energy will permit a larger overprint than a solder mask with a lower surface energy. In

The MoonMan has spoken. Everybody get back up on the wall, its been long enough that this has been "off the wall". Wish I had more Rambus chips, just got my SMT process dialed in and ran out of stock. Damn.

We agree with all of what Patrick has said. Hopefully your equipment is capable of the ideal setup you describe with no back flow until the product hits the wave and then back flow until the product emerges the other side. One other reason to strive

A question for all you wave experts out there: We run our wave with a constant flow over the back plate. I know it's recommended that we set the back plate so that the solder sits just at the top of the back plate with surface tension keeping it fr

Our new Soltec Delta 3 has this feature (they call it mainwave pushup) where you can add up to 60 rpm to the pump after the leading edge passes over the wave. Unfortunately, our old Delta Wave doesn't have this feature. Ideally we'd like to set it
