The bare pcb has lead HASL finish. Components are lead-free and lead-free solder was used to solder the plate-through components. Is this acceptable or will there be reliability issues?

Yes, sorry, I have no detailed experience with wave-soldering. Probably if you use Pb components with Pbfree wave, you risk contaminating your wave solder pot. I don't know how much it would take or what all the dangers of that are, other than the

Hey there ya'll!! I went and looked at the used equipment page here, and I've also looked around at a few other sites to try and find me a used PTH dynamic solder pot...like a Airvac type of unit. It doesn't have to be as fancy as a Airvac, just

we have some rebuilt wave soldering systems in stock ready to be shipped. epk-ii smt with lambda wave, chip wave ,omega wave. 4 preheaters,jacking stand roll out computer control. machine is in a great shape. another machin upk15f with 6 preheaters

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

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

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

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
