No Disadvantages The reason they are used is they cool the boards at 2deg/p/sec leadfree spec for N2.Remmember the chinese have been building LF for years and are more advanced that Europpe nad America and most of the equipment is backed by Japanese

I too was curious but afraid of being called names or being accused of being born in the "wrong" country. I know why lead free has to be cooled, but wanted to know what Tonka had seen? His thread almost makes it sound like they inert ans cool at th

I am waiting for additional information so I can better understand the N2 system and will respond when received.

Hello Everyone, I am wondering what you are paying for Nitrogen (N2) in for your re-flow or wave, in $ per m3/hr. Please get back to me so I can determine some long term operational costs. Best regards, Gary Z.

We are considering purchasing a Nitrogen generator rather than using a separate nitrogen tank outside the building. Here are my questions: 1. Has anyone out there used one before? Our model comes from Tamura and is priced around 50K 2. Would there be

All: All you using a nitrogen atmospheres with your lead-free waves? If not, why not, as I would think this might have benefits vis a vis reducing dross.

I'm sure this isn't the same situation, but we did have a selective solder machine with crazy dross and solder ball build up. Turns out the operator switched the low pressure nitrogen line used for solder level and the high pressure nitrogen line fo

Not sure if this helps but found this site that outlines % of N2 against O2 ppm levels. You need 99.99% N2 purity for http://www.tkb-4u.com/articles/consumables/whatisnitrogen/whatisnitrogen.php Most customers we have worked with in the past run an

I want to know the advantage of using complete inert soldering wave machine (with Nitrogen, Tunnel concept) in comparison to use just a soldering machine withe inerted solder pot. Thanks
