We are using a nitrogen generator (with a N2 storage tank) that feeds 1 selective solder machine. I do not know which type of generator it is. The N2 generator has an oxygen analyzer on it. The selective solder manufacturer recommends a N2 purity

I am curious to know how others are providing N2 for their lead free selective soldering process. If you are utilizing a nitrogen generator, is it a PSA type or Membrane type? I am trying to get a handle on nitrogen purity and what purity is necessar

What are the continuing costs on the N2 generator? Is there replaceable media that needs to be monitored/replaced at regular intervals to maintain N2 generation? We're currently using tank-supplied N2, but are just getting ready to fire up our sele

Liquid is significantly cheaper than compressed gas tanks if you are in continuous production. Of course, it will eat your lunch if you're running things for a few days, then the machine sits idle for two weeks. It boils off whether you use it or n

Per our selective solder provider, they recommend a PSA type generator to supply the needed 99.999% pure N2. The membrane type (which we have) does not provide the minimum (99.995%) purity necessary for lead free wave soldering. They happen to sell P

Our nitrogen generator and an air drying unit came with the selective solder machine when it was purchased new in 2008 as a package deal. We originally were feeding the system with air that was not properly dried. That lead to some maintenance cost

Charlie, For the 300 cylinder (the largest Airgas sells), it's going to cost about $66/cylinder for the gas (plus delivery charges). They also charge a $99/year lease for the cylinder. Based on those costs, and a low-end N2 generator system that I

On our Pilarhouse Jade we use nitrogen to cool the belt that drives our solder pump as well as keep the amount of oxygen to a minimum in our solder pot to reduce dross.

We have the opportunity to buy a new selective solder machine and are used to using a very old Jade machine with a moving tank and wetted nozzle. I have two process concept questions: Which is better- move the board over the nozzle or move the nozz

I use a two machines from EBSO, Germany. It's a machines with PCB carrier, so, solder pot is fixed. I'm fully satisfied with this equipment, but I use only wettable nozzles. If you would like to buy a new machine, not in used condition, EBSO will be
