Because there is no reasonable costing high temp solder to replace the existing high temp solder it has been exempt from the lead free requirements. I will look through my archive documents about this subject but I am pretty sure this has been approved and is part of the new lead free requirements.

I know most everyone is out for the Memorial day holiday, so this will be something that everyone can look at on Tuesday... My question is; what are the spheres going to be made of for "Lead-Free" BGA's? What about the BGA's (ceramic ones usually) that have "High-temp" balls? The high-temp balls are mostly lead, right? -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 847-509-9700 ext.5315 ----------------------------------------------------- STATEMENT OF CONFIDENTIALITY: If you have received this e-mail in error, please immediately notify the sender by e-mail at the address shown.
