Hi all! We've been building an assembly here for quite a while, and just recently experienced quite a bit of failures at ICT with one IC. Out of 50 assemblies, only 3 passed. The failures on the rest of them have been with one IC at the same location. I've x-ray'ed the failed parts and don't seen any broken or missing wire bonds, so I wanted to take a look at the die area to see if I could spot something obvious. -Steve Gregory- > I have done this a few times with a 1/8" end mill.
