Another benefit to low O2 levels with Pb Free is increased mobility of the alloy during soldering. It is an effective mobility enhancement in reflow as in wave soldering.

De-Humidification cabinets. The draw back with Nitrogen is that it does not reset clock life. The De-Humidification cabinets will remove moisture and has been added for some levels in the standard.

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

We have used some sealed steel cabinets and a nitrogen generator (Balston 75-79 model) for about a dozen years with no issues at all. Humidity levels average 1% - 5%. We also just bought a couple of XDry (Totech) desiccant cabinets (XD2-1104-02) for

We have a Vitronics SMR400N oven and many times need to use N2 inerting. My problem is that it takes close to an hour of operation to purge the system to achieve the desired O2 levels (~40PPM). This is not only time consuming but results in an inordi

Cabinets that utilize nitrogen or desiccator units are available that will accomodate the feeder so the parts don't need to be removed. Simply put the feeders into the cabinet at nite and remove them in the morning. Dr. Storage is one. A Google se

my experience: End '80 beg '90 we use a solution like that. Along the assembly lines, next to P&P machines we use to get dry cabinets (cheap and simple cabinet) where to put inside of SMDs (reel & trays once out of MBB ) during the waiting time from
