Hi,
I have used everything between metal foils taped on a desk to a MyData MY600 paste printer.
High quality probably means the final paste image and that is dependent on many items. Squeegee pressure and speed control is primary. But then so is stencil alignment. And foil thickness and paste type. I think these affect quality more than the mechanical stencil printer.
And the low cost issue depends a lot on how many boards of how many different types you print. Cleanup is a big parts of the cost due to time. Nice thing about real low end printer is they setup and tear down easily. The all hold a stencil quite well. Setup of the holding stage with shims and cardboard takes time ans is a majore setup cost.
Quality is also dependent on operator skill and inspection / touchup.
For me here in my shop a lowest end Asian made unit with no speed or pressure control works ok. But I only do prototyes here, never more than 25. And I print one up boards so the size of the stencil is small. If you plan on doing 20 x 20 images that is a different universe.
As for the My600 printer at $200K a piece they can be well worth the dollars. At AA they were doing 10 to 20 jobs a day and spending $1000+ a day on stencils. The My600 was a real fast payoff. And the first time I looked at a printed board my jaw droped. Dropped down below where it dropped whan I first saw the price tag.

We use Transition Automation for our prototype and odd shaped boards that will not run in line. We have used them for the past
25 years and no complaints. Easy to set up and use.

Hi,
We want to bring in house a high quality, low cost manual stencil printer for prototyping / reflowing several of the same PCB in a batch run.
There are many, many models out there to choose from, but the specifications seem to be limited.
If you can recommend one, please do so. And if there are ones to stay away from, then please share this, too.
Thank you,
Bob Cochran
