October 1, 2007 I recently reviewed an OEM'S ESD control procedure that required cleaning solvents to be conductive for use on any ESD sensitive assembly. i also seem to recall reading this same requirement in some ESD specification. Using conductive cleaning solvents does not seem like the right technical thing to do. Although it may help regarding ESD protection, seems to me we are at greater risk in event some of the solvent remains on the assembly after the cleaning process. Normally, our OEM'S use DI water and/or alcohol for cleaning non-rosin based flux and for RMA flux, a solvent like Terpene with DI water or a saponifier and DI water. Are the aforementioned solvents conductive? I don't believe DI water should be since it should not contain ions. Any info on this topic would be of use. Thanks. --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 -----------------------------------------------------
