Thank you guys. I will check this stuff out. It > quite possibly could be something we have done > wrong. Thanks again for the feedback Add anti seize to the threads. We do this to all of our nozzles when we first "tin" them with Active8. We usua

A while back, we had a yellow coating showing up on some solder joints at Selective Solder (LEAD alloy). I contacted the company for our machine and he looked into it. One change we had made not too long before is we switched from Superior 75 to Sup

Who is using two sorts of tin in one selective soldering machine with to solder pots? So then the soldering program selects the correct pot (tin). What are the risks? Adding wrong tin in the wrong pot. Mixing up the nozzles?

We are using Superior 515 flux to clean and tin selective solder nozzles. Yesterday the flux turned a bright yellow (like a highlighter) when heated after the flux being applied. This does not happen with our Lead Free solder, only the Lead alloy.

You should also remove all the pump parts and clean them, checking the bearings and seals. Clean completely the parts that allow the solder to flow back into the pot; ours have a spiral that fills with dross. Treat yourself to new nozzles. Tinning

Bill, ENIAC, Thank you for your input. I'll do some research on the items you suggested and give it a try. The idea of having a steal nozzle that is tinned is defintely new to me, so I will check into that, as well as the brushes. Thank you guys.

Maintenance, solder type, and tinning flux chemistries are going to have an impact on nozzle life. Doing regular maintenance and using a good quality nozzle you should expect your nozzles to last 6-8 weeks when running a single shift operation. Keep

I have found Superior No. 75 to be an absolute miracle worker when it comes to nozzle maintenance. I let our worst nozzles soak in that over the weekend and then the majority of the dross would literally flake off with light pressure from a pick/scre

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
