Is there a difference between the Nitrogen cabinet vs Dry cabinet ? How does this helps in creating safe environment for MSD storage. I felt puzzled when my customer rejected me coz' I'm using the Nitrogen cabinet instead of dry cabinet. Except for t

The customer said " The Nitrogen PPM is questionable". LIke what I said, as long as I have met the 10% RH, it should be OK, rite ? thx

Good question. What did your customer say?

Has there been a definite date for the total move over to lead free? Will it be 2004 or 2008. Also is there a direct replacement for leaded solder, I have read various articles on numerous alloys suggested for the switch, such as bismuth, tin, copper

Truthfully, there are pro's and con's for both technologies. (put cost of ownership aside for one moment) Nitrogen won't dry humidified components as rapidly as a desiccant dry box. I'm talking about a self regenerating dry box that uses molecular s

On an assembly reflowed in air saw the same thing: 0201's with a grainular solder joint, but 0402's and above with perfectly formed joints. Reflow profile all within acceptable tolerances. Reflowing in nitrogen solves this problem, but increases t

Check out my article about reflow soldering in nitrogen atmosphere on www.smtinfocus.com Hopefully you will find some answers and more detailes on my web-site.

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.
