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

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

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

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

IPC610 training to help verify issues that might arise. Also, the opeators need to know part numbers and descriptions because that should be common knowledge when running a SMT line. Plus, with your comment "At our company they know how the pick&plac

Regarding your question about buying equipment to vacuum seal the MBBs, according to the IPC/JEDEC standard, "Full air evacuation is not needed or recommended; light air evacuation will reduce the packaging bulk and enhance carton packing. Excessive

Chances are this is not a component failure. First, these are passive components with passive testing on the ICT. He may have guarding issues, but more information is required as has been stated. Are all capacitors with the same P/N failing in dif

I want to place a connector near the edge of a PCB using a Panasonic Pick and Place machine. One-third of the connector (the part with the smd pads) sits on the PCB, while the remaining portion hangs off the edge. When the connector isn't seated prop

Ideally need to understand the board & part more. I place parts through the board with a Panasonic AM100 & standard nozzles. I just had a custom tray made to hold the parts for pick up...
