Thanks , Reese.Yes , I check the capacitors with C-meter.When measured with C-meter , all capacitors are OK - +/-10% of the value. I can not underst?nd "Note: This is not a summation). Y5V -- -20% of nominal value, -part tolerance, -machine toleranc

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

Have you verified the measurements on the bench with an LCR meter? Chances are you are experiencing aging with these ceramic caps. We have similar issues with X5R and X7R caps. You will see the effects of aging with returns from the field as well

I am wondering what skills operators need to run an smd line itself. At our company they know how the pick&place machine works (refill/ changover), but if there is a problem with wrong placed components they don't known what to do. Our managmenttea

Our lines have operators on all shifts capable of doing programming start-to-finish and can deal with almost any program related problem. We are high mix, low volume. Our builds are sometimes one of a kind with qauntities of 20 or 30. We empower a

We have a system where when we set up the line to run a job before the first part is placed an auditor verifies we have all the correct parts loaded on the machines in thier correct locations. We then run a first article. The board is inspected to in
