Does anyone have a motor frequency inverter(driver) for an ERSA Versaflow, that you can sell me? It says "Seidel" and then "digifas 7200". I know this is a long shot, but even if it's used I'll take it.

Funny that you post this, but I just had one of these go bad on me. ERSA Field Service came in and replaced it.

Using a meter to check a BGA connection to the board, there will be other parts of the circuit involved. Sounds like a bad batch of parts.

We have not had very much luck hand dispensing on small pads. It can be done but you will most likely have bridging and insufficients.

If it's only 30 boards why not just get a stencil foil and hand print it? It's a piece of cake...

I agree with Steve on this. If you just order the stencil you would probably save more money than have to fix the boards if you were to do it manually. Most stencil houses for new accounts will let you get a free sample screen as an evaluation.

I've cut component patterns out of old stencils. Not as good as buying a new mini stencil but still it worked. I guess you can't buy those pre-pasted boards? I've never tried them but they look interesting.

You can get prototype stencils for $140 from Stencils Unlimited. I've never used their services but I have considered it. The stencils are frameless and even come with a hand squeegee for you. http://www.stencilsunlimited.com/prototype_stencils.ph

If you do find one, you will want to cut some kind of "handle" with it. You might want to practice cutting a different pattern first, if you only find one of the pattern you need.

you should be able to work out the resistance of the heater element from the power rating (watts), and the Voltage its working at. then measure the resistance of the element and see if your anywhere near.
