A manually trimmable capacitor is often subjected to damage if the operator who tuned it applies too much force on the part. Also, excess compression during the tuning process leads to possible drift in capacitance values (from the set value) due to after tuning stress relaxation. Sometimes, when the part is partially damaged during the tuning process, drastic changes in capacitance value may happen in the field due to worsening damage caused by mechanical vibrations and shocks.
