Michael,

This is not my area, but it is possible that the fumes are coming from Lead.

I'm a board fabricator that sub-contracts to an assembly shop to run
some boards through a reflow assembly shop.  We've recently
(significantly) increased the volume of parts going through this
process.  The assembly shop is complaining about a "noxious" odor while
runing these boards.  While they are trying to figure out how to capture
the fumes, I'm trying to figure out what they are.  I have an Industrial
Hygenest who can tell me how much of something's there, if I can tell
him what it his.  MSDS's being what they are, I'm not too confident that
I'll be able to isolate all the possible candidates.

I figured from the worldwide audience of assembly experts on Technet, I
ought to be able to get a couple of ideas about what the odor might be.
Does anyone have any suggestions?

I'd also be interested if anyone knew of a lab that could bake a board
or two, capture and analyze any volatiles emitted.

Thanks in advance for any feedback.
