We using nitrogen only for Selective Solder machine, you don't need it for reflow oven, to improve solderability we use Vapor Fase oven.

No problem running lead free without nitrogen. Careful profiling will take care of the soldering. Cosmetically, the Nitrogen reflow is superior for lead free, and we see much better wetting, better coverage of the PWB pads, and of course the smooth

Nitrogen in Reflow is grossly over-rated...., in my opinion, and in the opinion of several very well known SMT Industry "God Fathers". Way too much $$$, for a slight increase in the process window. If you profile your oven specifically for your pr

I have been involved with the reflow process for many years. However, my most recent position now includes the use of Nitrogen. In studying the reflow process and using Nitrogen, it seems to me that it would only make sense to be measuring the O2 lev

| 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 inor

Hi CKH, Here's some things to consider: 1) Moved by obstruction in/entering oven, such as nitrogen skirts 2) Incorrect air pressure/air leak in oven (large surface area on component) 3) Reflow temperature too hot & electrolyte/air in cap is expandi
