If you add any "flux cored" wire solder to the pot make sure you have ventilation as the flux will burn off and smoke like crazy. This solder pot is like any used in a wave or selective solder, no flux. The flux is added to wire prior to di

Grant, the BGA Kid's got a great point. You state, simply that you're looking to completely replace wave soldering with selective soldering, but the only reason given was "the wave is old". The throughput differences will be huge if you're solderin

Matte solder mask greatly reduces the potential for solder balls, and since you altered the machine parameters with no improvement it might be flux related. Do you use a VOC free (water based) or alcohol based no-clean flux? Do you use machine settin

Yes, the previous "non-balling" flux was alcohol based, but very weak activity. We found it was worth the switch to water-based, to get prettier solder joints - but...at the expense of having to "brush off" solder balls on a couple of assemblies wit

Yes, the mask finish is prolly the #1 contributor to solder balling. Seen it many times. It's not that it's cured or not, went down that path about 3 or 4 times as well. Different fluxes can help too. But also check your preheat. If your are get

It sounds like the flux is not holding up during the soldering operations. That would account for the webbing, etc. Also is the problem specific to a certain board type or lot code of boards? Do you think that your boards are outgassing during solder

So It happens that we are having an installation crew here working on our second wave solder machine. It is a Vitronics Soltec that we bought for lead free processing. I personally used Ekra and vitronics and Electrovert at other companies. I believ

Oooo, I just thought of something else. Consider the capability of the fluxer on your wave solder machine when selecting fluxes.

Hi Kevin , we use frequently double reflow + selective soldering after , and try to avoid the glue process as much as possible because that 's not very reliable process in comparison to reflow process . We begin now to work on PTH components soldered
