It's come time to upgrade our Glenbrook RTX-113 x-ray with something that has a little more "balls", as it were.
I've been looking at their 90KV "Jewel Box", figuring that has enough power to keep us in the game for the future.
But in speaking with an engineer from a company that we've been talking to about some potential business, who has had some failures on some Xilinx 1152-BGA's, he says that almost all 3D x-ray machines he's familiar with have trouble dectecting voids and such when you start looking at the BGA's at a 45-degree angle. The metal top can be seen through from a 90-degree angle, but then you're basically back to standard transmission x-ray performance just like I have now with my RTX-113. He says the only thing he's found that he has any confidence in, is a 5DX. I wish we had the kind of money to afford a 5DX...
Do any of you use something other than a 5DX to inspect Xilinx 1152-ball BGA's? If you do, would you mind sharing what you use, and how well it performs?
Thanks in advance!
