Research on Residual Carbon Content and Electrical Properties of Nickel Electrode MLCC After Glue Removal
The inherent organic residue in the green body of multi-layer ceramic capacitors(MLCC)leads to low product reliability,which is mainly due to insufficient glue removal.By changing the different process conditions of the glue removal step,the residual carbon content of the green body after glue removal is quantified using a sulfur carbon analyzer.Combined with destructive physical analysis and scanning electron microscopy,the structure of the fired product is analyzed,and the electrical performance of the finished product is tested to explore the relationship between residual carbon content and the electrode continuity,electrical performance,and reliability of the finished product.The results show that the residual carbon content after glue removal can be effectively reduced by increasing gas exchange,reducing the heating rate of glue removal,and extending holding time.The continuity of the internal electrode of the fired MLCC becomes better,and the electrical performance data such as capacity and breakdown voltage are improved.The dielectric layer becomes denser and the service life becomes longer.The discussed methods for determining the adequacy of glue removal and increasing the adequacy of glue removal can provide a reference for glue removal operations in MLCC industrial production.
