It never ceases to amaze me how topical these - um - topics - are. I just sent a box of boards out last nught to an x-ray shop. (same boards I asked about earlier, this time with lead free BGAs). We're getting strange results and assumed there's opens in the BGA. I don't have a lot of confidence that the used a hot enough profile for a big board with many copper planes, so I'm expecting some non-wetting. Can I assume from this thread that they very well might give these boards a passing grade, yet we could still have opens? The lab says they can do angle x-rays, we turned down another shop that said they do top-down only. One of the suspected opens is in row 2. What about a BGA scope for that one? --------------------------------------------------- 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 -----------------------------------------------------
