Let's not start Lead oxide panic please ; takes a MUCH more than reflow oven to fume lead ! paul -----Original Message----- From: Chad Gustafson [mailto:[log in to unmask]] Sent: Friday, 20 August 1999 8:44 To: [log in to unmask] Subject: Re: [TN] Noxious Fumes from Reflow Operation Michael, This is not my area, but it is possible that the fumes are coming from Lead. Chad Gustafson Manufacturing Engineer JMSPI >>> "Mcmaster, Michael" <[log in to unmask]> 08/19/99 04:29PM >>> 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. ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
