Hi Inge, I'm surprised that Dewey didn't pick up on you Freudian Slip. You wrote "has anyone of you experience from 'Die & Pray' technology?" Let's hope not ;-) KennyB -----Original Message----- From: Hernefjord Ingemar [mailto:[log in to unmask]] Sent: Thursday, October 22, 2009 1:44 AM To: [log in to unmask] Subject: [TN] [spam] RE: [TN] ENIG Issue By the way, speaking SJ issues, has anyone of you experience from Die & Pray technology, like the one described by some guys, who tested large game boards, see figur 9 and 10, dye and pry testing? It's not easy to pry so large BGAs. What kind of tools etc do you use? Myself, I had to dip the board under test in LN2 before prying off the superBGA. That's not good, the low temperature can mislead the result. /Inge http://www.celestica.com/uploadedFiles/Home/PBfree_process_paper.pdf --------------------------------------------------- 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 -----------------------------------------------------
