Effects of Lead-Free Solders on Flex Performance
Ceramic capacitors have proven themselves very reliable with extremely low failure rates. As processes continue to improve, reliability of the dielectric also continues to increase. This increase in the reliability of the dielectric has caused other categories to emerge as the main contributors to the overall failure rate. A recent review of field failure analysis of surface mount MLCCs, has sh...
متن کاملFailure Analysis of Dielectric Breakdowns in Base-Metal Electrode Multilayer Ceramic Capacitors
Leakage current measurements of BaTiO3-based X7R multilayer ceramic capacitors (MLCCs) with base-metal electrodes (BMEs) have revealed three distinct failure modes: avalanche breakdown (ABD), thermal runaway (TRA), and slow degradation. Failure analysis (FA) was performed for a number of BME capacitors that failed with the aforementioned three failure modes. The samples that failed with ABD had...
متن کاملDeveloping a Method for Risk Analysis in Tile and Ceramic Industry Using Failure Mode and Effects Analysis by Data Envelopment Analysis
The failure mode and effects analysis (FMEA) is a widely used analytical technique that helps to identify and reduce the risks of failure in a system, component, or process. One important issue of FMEA is the determination of the risk priorities of failure modes. Risk ranking is produced in order to prioritize the focus on each of the failure modes that are identified. In this study, we applied...

متن کاملDesign Guidelines for Preventing Flex Cracking Failures in Ceramic Capacitors
Surface mount multilayer ceramic capacitors (MLCCs) are one of the most common components found on modern circuit card assemblies. Introduced in 1977, they are well known for their reliability and have been rapidly accepted by the electronics industry. The reliability of a nominal MLCC is extremely high, with expected operating lifetimes in the decades, if not hundreds of years. However, to att...
