Hi all, We are looking for new analytic X-Ray system especially for BGA and QFN solder joints inspection. Most of the leading systems use open tube. However, there is one manufacturer who declares that he use closed tube -"Sealed transmissive type of X-Ray tube" According to this manufacturer, the best system can recognize 100nm features size-which is fantastic! My question: If you know how this sealed tube works, what is your opinion regarding the differences between the usual open tube and this specific closed tube? Which technology is better? Thanks, Eli. --------------------------------------------------- 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 -----------------------------------------------------
