Generally, a capacitor is considered to have failed when its capacitance drops by 3% or more compared to its initial value. The probability that a failure will occur is called 'failure rate'. There are two types of failure rates: average failure rate and hazard rate (instantaneous failure rate).
Capacitor defects significantly contribute to infant and latent failures in integrated circuits. This paper will address methods of locating capacitor defects and root cause determi-nation. Keysight Technologies' failure analysis team investigated tens of failures in an externally purchased voltage controlled oscillator (VCO).
A capacitance value significantly below the nominal rating is indicative of dielectric failure or deterioration, necessitating replacement. Visual inspections should complement these tests, particularly in high-power circuits where capacitors in power supply filter sections are more susceptible to failure.
For film capacitors, the typical failure mode is capacitance decrease due to self-healing, so it is possible to diagnose the life expectancy by understanding the capacitance change. Capacitors fabricated with reliable technology and strictly controlled processes can enhance the performance and reliability of electronic circuits.
Mica and tantalum capacitors are more likely to fail in the early period of use (early failure), while aluminum electrolytic capacitors are more likely to experience wear-out failure due to aging use. In the case of film capacitors, when a local short circuit failure occurs, the shorted area may temporarily self-heal.
When current repeatedly flows into a defective part due to overvoltage or dielectric degradation, the capacitor continues to self-heal and loses capacitance. Generally, a capacitor is considered to have failed when its capacitance drops by 3% or more compared to its initial value. The probability that a failure will occur is called 'failure rate'.
