The low value will be 0.624uF. You have to factor it from the low tolerance (-10%). So: 0.9 x 0.92 (machine tolerance) x 0.91 x 0.91 x 0.91 (3 decade aging factor for X7R dielectric). We factor hours at the 3rd decade (10,000 hours), but you can

If they're 1 1/2 years old, they are definitely aged parts. Either send them back for newer or widen your tolerances on the ICT to compensate. You are at the 3rd decade now (10,000 hours) and you will need to compensate for this. These parts are n

The first picture shows an issue. Note that the vias adjacent to the interior rows are filled with solder. At the outside rows this is not evident. What you might have are interior spheres that are smaller in volume than the rows on the outide, si

1st X-Ray looks pretty good. One instance of what looks like solder migration in the lower left quadrant. 2nd X-Ray shows a number of locations where the solder has migrated into the vias, shown by the small dark circles between the main spheres.

I think we are all on the same page with this one. Since you ran from 96 until now without any issue I'd say that now you know what causes the problem, make a note of it for next time and move on. I have found with our older machines that "if it ai
