Ceramic Capacitor Aging: What to Expect
Soldering is a common process for deaing ceramic capacitors but is not the only way to perform deaging. Another common and equally effective method is to place the capacitors in a 150ºC oven for a min-imum of 30 minutes. The time above the curie point is not critical and once the capacitor reaches above the curie point, deaging occurs.
