| Abstract: | Oxide film reinforcement technology was used to form robust oxide film to resist mechanical stress on the outer surface of tantalum anode. Simulated reflow soldering process for tantalum Capacitor and made a study on DC leakage current change before and after reflew soldering and influence of reinforced oxide film on breakdown voltaoe. The result of tests showed for the capacitors prepared with reinforced oxide film, the rise of DC leakage current before and after reflow soldering has reduced by 14% compared with the capacitors prepared with conventional production process; Breakdown voltage measured is 6V higher than the capacitors prepared with conventional production process. |
