We have recently aquired an MPM SPM stencil printer with an under stencil wiper. I have a list of approved solvents from MPM, but before I go and buy one I thought I would see what the fine people of SMTnet are using for their wiper solvent needs.

I have an MPM SPM and two Ekra E4 screen printers. I have always run them dry with vacuum. I am also using no-clean paste and have not had a problem. The volume I run per day on the machines is 4 - 6,000 bds

I personally believe that you money is best spent on improving your process. An automated printer will help make your process more repeatable, thus easier to control. An AOI will not improve your quality, it will only make your defects easier to dete

I would try it dry first, we have never used solvents in our SPM, AP-20 or UP2000. Wipe every 4 to 10 boards. Normally dont have to wipe when using epxoy.

I have used MPM 3000 and Dek 265 Horizon. We always just fill them up with regular old alcohol. Cheapest and easiest way to maintain.
