Ceramic Capacitors and resistor knowledge:

Failure modes and mechanisms of resistors
 
Failure mechanism: physical, chemical, thermodynamic or other processes leading to failure.
 
The main failure modes and failure mechanisms of resistors are
 
1) Open circuit: the main failure mechanism is the burning of resistance film or large-scale shedding, matrix fracture, lead cap and resistor shedding.
 
2) Resistance drift beyond the specification: Resistance film defect or degradation, the matrix has movable sodium ions, poor protection coating.
 
3) lead fracture: resistance welding process defects, solder joint pollution, lead mechanical stress damage.
 
4) short circuit: silver migration and corona discharge.
