Hello, I am looking for input on the 7 zone convectional reflow oven on the temperature profiling. I having a problem with the flux/solder spattering on the Au cotact fingers. I have ran some experiment with the soak time and reflow time. Anyway,

As long as you have a continuous profile with required soak and dwell periods, the zone lengths do not matter. For lead free, usually ramp to peak is preffered.that is with minimum soak (you can not avoid soak anyway. You can achieve the profiles irr

Maybe here's an opportunity to get a new oven. Electrovert, BTU and Vitronics offer closed-loop N2 control as an option. This, together with other improvements on oven design can reduce N2 consumption by as much as 40%. Not to mention reductions in e

I need to setup an oven to run with a nitrogen atmosphere for boards with BGA's, but our ovens do not have the optional atmosphere monitor and controller. Is there a good way to sample and control the atmosphere without the optional built-in atmospe

Helium is even more expensive than Nitrogen. How about Argon?

I'd guess any noble gas would be expensive.

Electrovert has hard data on electrical and N2 consumption for the new OmniEXCEL series ovens to compare with preceeding OmniFlo series. Have a look.

We have been using nitrogen in our reflow ovens for many years to reduce oxidation on our solder joints. Management is concerned about the high cost of nitrogen and have suggested we use hydrogen instead. I'm not sure if this is a good idea, but we

Im not an expert at this, but im going to have to agree with blnorman. I wouldn't use Hydrogen, its very explosive. I would look into a considering a new oven to cut back on cost. Yes you will have to put out the money for a new unit, but if it reduc
