Improved SMT Performance of Tantalum Conductive Polymer Capacitors with Very Low ESR
نویسندگان
چکیده
KEMET Electronics Corp has implemented several process and material improvements in order to improve the surface mount (SMT) performance of low ESR conductive polymer tantalum capacitors. This includes large case size (up to 7343-43) capacitors with ESR as low as 5 mΩ. Six Sigma methodologies (DMAIC: define-measure-analyze-improve-control) were used to structure the improvement process. This paper describes the project goals (define phase), new measurement techniques that had to be developed (measure phase), the conceptual model to explain SMT failures (analyze phase), process and material improvements (improve phase), and new control measures put in place (control phase).

Characterization of Tantalum Polymer Capacitors
Solid-electrolyte tantalum capacitors were first developed and commercially produced in the 1950s. They represented a quantum leap forward in miniaturization and reliability over existing wound-foil wet electrolytic capacitors. While the solid tantalum capacitor has dramatically improved electrical performance versus wet-electrolyte capacitors, especially at low temperatures, today’s electronic...
متن کاملStrategies for Manufacturing Ultra Low ESR Ta Capacitors
Leading edge designs for portable electronic devices require capacitors which deliver volumetric efficiency, high reliability, low cost, reduced propensity for ignition, and low Equivalent Series Resistance (ESR). Tantalum capacitors employing a conductive polymer cathode are uniquely capable of providing all of these critical characteristics. Tantalum capacitors have a long track record for un...
متن کاملConductive Polymer Cathodes - The Latest Step in Declining ESR in Tantalum Capacitors
The ESR in a tantalum capacitor is a culmination of the resistivities associated with the contact of each capacitive element within the capacitor structure. The basis of the structure is an extremely porous pellet of pressed tantalum particles that are sintered in a vacuum to enhance the contact areas between these particles. The cathode contact is the deposited MnO2 material, which snakes thro...
متن کاملDetermination of Capacitor Life as a Function of Operating Voltage and Temperature
Background Potentiostatically charged Hybrid capacitors age predictably by a mechanism involving electrochemical reactions that reduce the efficiency of the cathode and consume electrolyte. One of these reactions results in the formation of hydrogen at the cathode which reacts irreversibly with the tantalum foil substrate. The material formed is much less conductive than the original. The conse...
متن کاملFailure modes of tantalum capacitors made by different technologies
Generally, tantalum capacitor failure modes have been discussed both for the standard manganese dioxide cathode and the new conductive polymer (CP) type. For standard tantalum in the normal operation mode, an electrical breakdown can be stimulated by an increase of the electrical conductance in channel by an electrical pulse or voltage level. This leads to capacitor destruction followed by ther...
