Hi TechNetters.
 
We recently discovered a problem on chip capacitors:  when examine carefully
with magnifying glass, we found a separation (Gap)  between the endcap
(metallization) and the ceramic.
 
When capacitors were pried with tweezers, the whole ceramic part came off,
leaving both, complete endcap in the solder joints.
 
Removed caps were examined under microscope and all we could see was a
brownish deposit ( look like glue ) where the two endcaps were.
 
I think it is a part manufacturing problem. Am I right to think that or can
something else have cause the separation of the endcaps ?
