Hi, I'd like to ask some tips about the merits and shortcomings o of both screen printer and stencil printer. For small quantity and highly mixed usage, which type of printer is suitable to our application? The boards contain no BGA and the fines

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
