| Gentlemen, | Can anyone provide information on selective soldering systems that compete with Ersa's VersaFlow? Does anyone have experience with this machine or other machines of this nature? | My company is considering acquiring to increase techn

They are expensive so you need to have a lot of jobs that take a long time to hand solder or have a ton of masking. Also look at bottom side wave soldering, if you are having a lot of defects, the selective will allow you to solder both sides in surf

We have 2 dual head Versa-flows in line. We use them mainly for doublesided reflow jobs that have connectors and axial parts. I have about 15 jobs currently running on them. The advantage of having 2, is some of our boards have through hole on 1 side

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

We have an ERSA Versaflow Ecoselect selective wave soldering machine. It works well except it needs nitrogen. You can't even move the table around if your nitrogen tank is empty. The spec sheet says Required degree of purity: Nitrogen liquid 5.0

I am having some problems with some of my pcbs at ive solder. We are using an ersa versaflow. It has an automated spot/spray fluxer (Interflux Pacific 2009M) , 1 preheat stage, a leaded pot/nozzel, and finally a lead-free pot/nozzel. Nozzels move, b

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

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

We have tested SN100C and SAC305 in our selective solder machine (Ersa Versaflow). We wanted to test both alloys in the selective first because the investment in filling the pots is minimal. In our initial tests the SN100C alloy appears to be the bes

I am a user of an Ersa Versaflow 3/45. I was wondering if anyone could share some process pointers. I have a 0.125" multilayer PCB that I am having problems consistently achieving 75 percent hole fill on a mini-coax connector. The coax connector ha
