Selective soldering machines are a good way to "finish automation", if the design of the PCB is conducive to the application with just a few components to solder. Your points are good. A decision matrix for selecting a machine might also include:

Key Issue: Will this machine solder your boards? You never know until you solder one. Any other avenues of analysis involve substantial risk. Flux Selection * High or low solids * VOC or VOC-free Solder Alloy * If using lead-free, avoid stainles

we don't have a nitrogen generator installed yet. The solder wave supplier recommends 99.99%. we hare received several submissions for nitrogen generators that meet the requirements.

We recently installed a new solder wave machine, The spray fluxer has a pressurized tank and because we use an alcohol based flux, the spray fluxer system must be fed with nitrogen. Anyone has infos on what installation is prefered to supply this mac

any advantages over other nitrogen systems, like cost, maintenance, installation, etc?

For fun ask the sales guy where they came up with that number. Or even the reasoning for using nitrogen. Don't expect quality answers.

fluxer requires normal shop pressure, around 100psi. Thanks for the infos, very useful.

The onsite generator drops approx. 30psi from the input. We feed ours 110psi and end up around 80psi in the tank, which we regulate to 65psi for the machines.

Sounds right, our actual pressure in the system is 120psi, the regulated to 100 in the machines.

Agreed. If it's just a means of propulsion/ atomization the purity probably isn't too critical.
