April 8, 2008 Sn62 solder contains 2% silver. Have folks experienced any issues using SnPb solder with this much silver? The historical QQ-S-571E solder spec indicated that using Ag2.5 solder can result in corrosion issues in a humid environment but I am not aware of any issues using Sn62 solder. My understanding is that using 2% silver helps when soldering to ceramic parts having palladium/silver finish. --------------------------------------------------- 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 -----------------------------------------------------
