Fellow Technets, Periodically, BGAs are reflowed using our AIR-VAC hot air rework station. RMA liquid flux is 1st flowed under the BGA prior to reflow and then clean afterwards starting with IPA spray followed by an in-line cleaner wash. Occasionally, flux residue remains which requires additional cleaning. I am in need of a creative and operator safe way to either spray/flow warm IPA or a mixture of hot saponifier/DI water (from our in-line cleaner) under BGAs to expedite cleaning. I do not know of any equipment on the market that can be used for this application. Welcome ALL suggestions and proven methods. thanks joe --------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8e 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/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 -----------------------------------------------------
