Doug Pauls Rockwell Collins Andre Leclair <aleclair@ANSENCO To: [log in to unmask] RP.COM> cc: Sent by: TechNet Subject: [TN] Aqueous Washes & lead free <[log in to unmask]> 05/12/2004 08:57 AM Please respond to "TechNet E-Mail Forum."; Please respond to Andre Leclair Morning all I have been noticing lately a number of Wash manufactures advertising their machines for Lead Free assembly processes. Are boards assembled using fluxes designed for the higher reflow temps (Wave or SMT) harder to remove with older washes ?? or is this an advertising gimic to try and sell new machines?? We currently have 2 older Westkleen (Triton IV & Formula 3MT) and are looking at introducing a lead free line next yr. --------------------------------------------------- Technet Mail List provided as a 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/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ----------------------------------------------------- --------------------------------------------------- Technet Mail List provided as a 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/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 -----------------------------------------------------
