Hi Bev, I would hazard to say that this is a language translation error, because of course, there is a "LIFETIME for the ABILITY to mass SOLDER" moisture sensitive devices without *damage*. Now convey this concept into two concise words in Japanese and you might say something about the toilette. As a matter of fact, being the end of the day, I can think of a good way to express such a concept in just a couple of words in english.

This is from one of the largest off-shore electronics manufacturers in the world. Is there still a chance they are completely wrong ? Yeeees, but it doesn't look good. We are investigating. And also asking if this is true, why? Rudy, good question about the finish. It is tin over nickel over silver. I don't know the thicknesses - yet. regards, Bev Christian Research in Motion -----Original Message----- From: Sokkhon Ou [mailto:[log in to unmask]] Sent: July 23, 2003 8:10 AM To: TechNet E-Mail Forum.; Bev Christian Cc: [log in to unmask] Subject: Re: [TN] Short Solderability Time Limits You will find all detail about MSD in IPC/JEDEC-J-033A. It talk about moisture not soldering.

We have received virgin parts where the label on the bag says they only have a SOLDERABILITY LIFETIME of 168 hours after they are taken out of the bag! This is not a case where one can recover them by putting them in an oven afterwards! Anyone else seeing this new pain-in-the-neck development? regards, Bev Christian Research in Motion --------------------------------------------------- Technet Mail List provided as a free 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/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ----------------------------------------------------- --------------------------------------------------- Technet Mail List provided as a free 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/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ----------------------------------------------------- --------------------------------------------------- Technet Mail List provided as a free 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/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 -----------------------------------------------------
