My company has had the same issue on our Versaflow 366 with SAC305, we tried ultrasonic cleaning and it worked for a shift and then was clogged again. We have had the machine for 3 years and we have had to replace the gassing rings twice so far. We a

Iron huh? You sure about that? We have the ERSA Versaflows and our nozzles are made out of ST37 Tool Steel. There is an "American equivalent" to this grade but I forgot what it is. You'll have to google it like I did. Anywho, Tin or Tin-Lead sold

Hi I recommend you to check the exhaust sensor, the ERSA EWS500F is sensing the exhaust before it activates the fluxer. If the exhaust is not working then machine does not start to avoid the sprayed flux emit to the work environment. There is a sens

Hi John, Our ERSA rework station came with a soldering iron that has a few special tips. We normally do not have a stencil and use tacky flux, so I use the concave tip to prep the pads. This leaves solder on the pads but with a little practice you

I believe the training was just a couple days after the installation. It really depends on how many people will be trained and previous machine programming experience. Programming the machine is not that hard; however, it's time consuming sometime.

We have a Versaflow 40/50 and ours is setup like this. We have out nozzle test position set so that in the Z axis you are 3.8mm away from the pin. Used feeler gauge Then you can set your gradient per nozzle. Start with a number then do a wave offs

I can't think of any off hand other than the Ersa which is massive and from when I used it a pain in the A*SE to program and keep programmed, you always seem to have to baby sit it. I bet if you asked you could get one, the problem is that forced con

If you do not have a lot of TH joints there are some advantages. No boards "submarined" in solder pot on wave. You can solder the bottome side SMT parts rather than epoxy them when the parts are put down. This should reduce SMT defects and missing pa

Do you watch when it is doing the wave height test? Watch it and see if it goes up to the same spot on the test probe each time. If the test probe is dirty sometimes the solder has to go up higher on it before it gets detected. You might actually be

You will need to preheat the boards for a lead free selective solder process. A preheat module is critical for any wave or selective solder process, if you don't get the board preheated properly the solder is going to resist flowing to the top of the
