We are a contract builder that manufactures printed circuit board assemblies and apply a silicone conformal coating to those assemblies. Our coating process is not isolated from the assembly and test area. We use a Sn63Pb37 solder process in both our smt and wave solder areas. This has been our process for at least the last 15 years. We are being told, by a potential customer, that we are risking silicone contamination of our solder joints as a result of our coating process being in close proximity to assembly and test. What are the risks to solder joint quality, if any? 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 -----------------------------------------------------
