March 8, 2008 Does anyone have test data that shows the degree of oxidation that may occur on pure-tin (<3% Pb) plated copper or other base metal component leads, when the components are subjected to electrical burn-in testing for 96 hours at 125C, 150C, 175C (similar to the MIL-PRF-19500, Appendix E screening test)? What is a safe temperature for electrical screening testing that will not cause the components to fail J-STD solderability test? --------------------------------------------------- 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 -----------------------------------------------------
