Tech-Netters:
A vendor recently received back from us a batch of multilayer
ceramic chip capacitors that failed their dissipation factor specification.
They claimed that the parts were merely aged and put them through a
"de-aging" process, apparently a vacuum bakeout. The parts now meet the
spec! Does anyone have any idea what the process is and what it does? How
long will the parts remain "de-aged?" What about parts already installed;
does D increase with age on all parts? Do you have any citations in the
literature? Can the de-aging process work on humans?
Thanks for your help,
