The high-end growth path of aluminum solid capacitor
The high-end growth path of aluminum solid capacitor
Aluminum solid capacitors are further divided into sub-pins and SMD products according to the production process. As shown above, the aluminum solid capacitors is manufactured by the above processes and processes. The entire roll is formed into a foil by cutting into various widths as needed. The anode foil and the cathode foil are riveted to the leads by winding, wound by electrolytic paper, and finally taped to form a core package.
The cut foil has no oxide film on the cut section. To form an oxide film on the cut surface of the foil and to repair the oxide film damaged when the riveted pin is repaired, the capacitor core package needs to be immersed in the chemical solution to be energized. The electrochemical method regenerates the Al2O3 oxide film, and this step is formed.
By the polymerization process, the monomer EDOT and the oxidant are mixed between the anode foil and the cathode foil at a certain temperature to react to form a polymer PEDT, and the solvent is volatilized to form a solid electrolyte.aluminum solid capacitors
Then, the core package filled with the polymer electrolyte was assembled, and the aluminum shell was placed for waisting and crimping, and the capacitor was sealed by an aluminum shell and a rubber cap. Then, the capacitor is identified by stamping, and the model, batch number and the like are printed on the top surface of the aluminum shell of the capacitor.aluminum solid capacitors
Finally, in the aging, the voltage of the oxide film is repaired by applying a voltage to the capacitor and adding a high temperature. After the repair, all the electrical properties (LC, CAP, tan δ, ESR) were screened. Then enter the appearance of the braiding link.aluminum solid capacitors
Minister Lu pointed out that the structure of the aluminum solid capacitors is similar to that of the liquid aluminum electrolytic capacitor, and the direct plug-in vertical package is used. The difference is that the cathode material of the solid aluminum polymer electrolytic capacitor replaces the electrolyte with a solid organic polymer material, and the coiled-type conductive polymer aluminum electrolytic capacitor is taken as an example, and it needs to be subjected to two impregnation treatments in the production process. That is to say, the solid electrolytic capacitor still needs to inject a liquid substance in the production process, and the difference is that the liquid substance injected therein is polymerized at a high temperature, and the solvent is volatilized, thereby forming a solid polymer inside.aluminum solid capacitors
Minister Lu stressed that the ESR value and static capacity of polymer aluminum solid capacitor are very small, both in low temperature and high temperature environment. They can have a long life of at least 5,000 hours at a high temperature of 105 degrees Celsius, and no longer There are concerns about capacitors drying up.
