Hi All, We encounter capacitor crack in the ICT, it contributes 2% of the failure. We are not sure whether these crack coming from the SMT. All these crack having the same pattern. Please refer to attached file. Anybody encounter the same thing befo

Solder Crack Counter Measures

Technical Library | 2023-11-27 18:19:40.0

This page introduces major causes and countermeasures of solder crack in MLCCs (Multilayer Ceramic Chip Capacitors). Major causes of solder cracks Solder cracks on MLCCs developed from severe usage conditions after going on the market and during manufacturing processes such as soldering. Applications and boards that specially require solder crack countermeasures Solder cracks occur mainly because of thermal fatigue due to thermal shock or temperature cycles or the use of lead-free solder, which is hard and fragile.

Flex Crack Mitigation

Technical Library | 2008-10-23 15:36:58.0

As part of continuous process improvement at KEMET, most failure modes caused by the capacitor manufacturing process have been systematically eliminated. Today these capacitor manufacturing-related defects are now at a parts per billion (PPB) level. Pareto analysis of customer complaints indicates that the #1 failure mode is IR failure due to flex cracks.
