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.
