cracked capacitors at SMT 1&2

Electronics Forum | Tue Aug 17 10:37:45 EDT 2004 | M.Enright

Some cracks are really obvious,straight down the middle of the capacitor.Some are slight hair line fractures which fail at ICT.In all cases seen,all cracks are through the centre of the cap.My worry is that there may be some which have fractures and

Radial capacitors have water gain

We have been having an ongoing problems with radial electrolytic capacitors (thru hole)for some time. 1. When we wash them in our inline cleaners the sleeving shrinks up from the PCB leaving the 'can' exposed. Some designs have traces on the surf

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

hi, i have problem with ceramic capacitor 10uF ±10% 16V X7R 1206.Problem is as follows:ICT ( Teradyne 8851 ) measured value 6 ?? 8uF ( about 70% of all lot).I decide that components ( samsung ) are defective.I buy one "type&reel" capacitors "Murata"

production lot is 4000pcs.About 70% of capacitors are out of tolerance ( +/-20%).There are 3pcs C=10u per PCB, in different location.Samsung capacitors wich we use are 1,5 years old - i checked this information from our supplier " Rutronik ".I have

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

Same pattern of capacitor crack

Hi All, We encounter capacitor crack in the ICT, it contributes 2% of the failure. We are not sure whether these crack coming from the SMT. All these crack having the same pattern. Please refer to attached file. Anybody encounter the same thing befo

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
