Mainstream Engineering Awarded Contract from the MDA for Developing a Revolutionary New Method for Screening of Capacitors
Over 95% of the multilayer ceramic capacitors manufactured worldwide use base metal electrode (BME) technologies. These capacitors are one of the key components in a wide array of modern electronic devices from cell phones to automotive electronics. Over the last 20 years, significant improvements have been made in the performance and reliability of BME capacitors, making them more competitive for a wide range of applications.
To increase implementation of BME capacitors in high-reliability platforms, a robust, reliable, and non-destructive screening method is necessary for evaluating BME multi-layer ceramic capacitors. This screening method is needed for both in-process steps and the finished device to increase the yields of high-reliability capacitors and prevent early catastrophic failure. In current methods, the partially complete or final devices have to be destroyed to check for the potential for failure.
To achieve reliability of these devices in the military and aerospace applications, Mainstream is developing a robust, sensitive, and non-destructive method of evaluating and identifying potential for failure modes in the component materials and the assembled BME capacitors. By enabling 100% inspection of all capacitors coming off an assembly line, this provides a reliable analysis of the dielectric layers, highlighting adverse effects to device lifetime.
Implementation of this technology in fabrication assembly lines will have an immediate and lasting effect on the reliability and performance of BME capacitors. In addition, yields will be increased and costs will be lowered by finding early failures in production materials and processes.
