Wenda <[log in to unmask]> To: [log in to unmask] <[log in to unmask]> Date: Thursday, February 18, 1999 2:21 PM Subject: [TN] gold embrittlement Dear TN, I am looking for a white paper or perhaps an article on the effects of gold volume to solder reflow reliability. Apparently NCMS had an article in ~spring of '96, co-authored by Wenger and Janus, determining that 3% was an allowable percentage. If you know how I can find this paper I would appreciate it. If you know of more recent studies that might help as well. Thank you, Rich. ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
