Thad, You are correct. I would not use Altera BGAs as a substitute for a Pentel. Except, perhaps, in filling out a SCAR for receiving parts with leaded solder rather than Pb-free, just to make a point, so to speak. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Thad Schultz Sent: Tuesday, November 07, 2006 11:59 AM To: [log in to unmask] Subject: Re: [TN] Altera BGA, lead-free or not? Peter, Is it just me or does this practice seem like a violation of good EDS practices? Seems like you could damage some gates in your part with the static generated by "writing" on a piece of paper. At least that is what I was taught in all my EDS training years ago. Maybe you throw the part away afterwards but some of those Altera FPGAs can be expensive I think. Or am I totally wrong here?

Hi Steve, We've found a simple test to determine the basic composition of the balls for BGA's to determine if they were lead free of not is to try and "write" with the balls on a piece of paper. If they mark the paper like a leaded pencil, then they are Sn-Pb. If they don't mark the paper, they are lead-free.

Mornin' Everyone! I've got a picture of the top of an Altera BGA to see if anybody knows if this is a lead-free BGA or not: http://stevezeva.homestead.com/files/Altera_BGA.jpg We're thinking that maybe the "N" on the second line of numbers on the part below the part number might be designating it as lead-free, but we're not sure. Good luck trying to call Altera and talk to a human being to find out for sure, because it ain't happening! -Steve Gregory- --------------------------------------------------- Technet Mail List provided as a 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/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 ----------------------------------------------------- --------------------------------------------------- Technet Mail List provided as a 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/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 ----------------------------------------------------- *** The information in this e-mail is confidential and intended solely for the individual or entity to whom it is addressed.
