I think we run our Vectra between 9 to 14 PSI. If memory serves me, I dont think you can set it above 14 PSI. We use VOC free no-clean. Your number seems WAY high. Check the nozzle. You also may need a different nozzle size. We always run a good filt

"Surface Mount Techniques has approximately 98 percent of the world market share of large Panel Stencil Printers". It sounds a little bit strange to me, especially since I work for one of the companys listed in their advertisement and it is definite

Can be done with AquaStorm 200, with some mods. I worked on a project a few years ago for a military company that needed to clean no-clean solderpaste residues from under LCC devices, we're talking like 2mil standoff. We ended up using a Zestron clea

We try and do it all (Vac pack, dessicant, indicator card, MSL level, PBT, end termination material etc.) however it throws a spanner in the works if you pull a manufacturer's sealed pack from stock and the vacuum has gone where an edge of a tray has

Depending on Zone Temperatures, Belt Speed, and Board Density... Some Convection Ovens will drop Zone Temperatures faster than others. They recover by increasing Air Circulation. This can make parts fall off the Bottom-Side that otherwise would

Sorry Bill We have filled and supported over 250 Lead free machines now and have actually moved the angle back to 7 degrees the same as Leaded and the bridging problems have gone away.Dwell times are only fractionally longer and results are very goo

Russ, I felt the same way before I took the job doing this, and actually only took the job after taking a weeks vacation to look at the machine. There is certainly some truth to Chinese companies basing thier engineering on existing well known suppl
