A capacitor is a crucial part of any electronic assembly, and a broken capacitor often results in a system failing completely. Capacitor failure analysis brings up specific issues that demand
Advancements in failure analysis have been made in root cause determination and stress testing methods of capacitors with extremely small (approximately 200 nm) defects. Subtrac-tive imaging has enabled a non-destructive means of locating a capacitor short site, reducing the FIB resources needed to analyze a defect.
Answers to the crack problem [1,2] To prevent board failures by failing ceramic capacitors the suppliers of the components took measures to stop catastrophic breakdowns even if they cannot entirely prevent the cracks themselves. First to name is the capacitor design called “open mode” or fail open” (see Fig. 10).
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).
Meters such as the Fluke 110, 170, and 180 series can provide the required data necessary to determine the presence of a failed capacitor. Although other test methods are available, such as live testing, this technical note is centered on testing capacitors in their de-energized state.
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.
As with externally fused capacitors, IEEE Std. 18 specifies capacitance readings in the 0 to +10% range. In reality, internally fused capacitors will be in the 0 to +2% range. These capacitors will show signs of failure in the following three ways:
