Background
CAF (conductive anodic filament) failures are an electrochemical migration (ECM) process causing short circuits within a PCB. Reduced via hole pitch and low loss resin systems (for high-speed and similar applications) have exacerbated the problem which often is only found in the field. The areas of concern this project will assess are:
- scaling and integration of laser and mechanical drill features,
- incoming quality measures of glass/resin systems, and
- manufacturing process factors that may limit future targets and demands.
Project Focus
- Utilize data collected to establish an improved understanding of laser and mechanical drill features. Assess opportunity to enable predictive methodology for laser and mechanical drill feature integration.
- Characterize incoming glass and resin system quality methods. Develop an understanding of sources of variation that may influence CAF and ECM; roadmap risk for new material development.
- Characterize process factors that contribute to CAF and ECM risk. Develop an understanding of process factors critical for new material development in support of PCB scaling advancements.
Project Benefits
-
Lower design reliability risk through characterization and study of focused incoming material and process factors driving CAF.
- Enable pitch scaling and higher density board technologies. Identify high risk PCB technology features.
- Develop a better understanding of CAF through hardware failure analysis and build awareness of failure mechanisms.
- Enable predictive methodologies for laser and mechanical drill features.
- Reduce product qualification costs and associated timescales.
