In the terminology of X-ray, does anyone know the meaning of "middle height splice"?

Regards,

Daniel

Do you mean middle height slice ? . This is a term used to describe the x-ray taken at a mid-ball position on a BGA ball , ie , the "fattest/widest" part if the ball . This is generally done to see if voids contained within have led to fracture across the ball as it cools .

Hope this helps ....

Thanks Andy. BTW, is the HP5DX able to provide such measurement?

Daniel, The 5DX can indeed. You program the inspection height just like you would any other measurement.

The term is indeed "slice", Daniel. I am the 5DX engineer here in Austin, TX. To answer your question, The 5DX can slice at varying heights of virtually any solder joint. By changing certain comment lines of the NDF and RTF files, the 5DX can view the joint at any height from board-top. It's actually very easy to do.
