A method for removing aluminum ions in the production process of aluminum electrolytic capacitors

Introduction

One of the most popular capacitor types in electrical equipment is the aluminum electrolytic capacitor (AEC). They have also been linked to corrosion brought on by aluminum ions. In this post, we outline a technique for eliminating aluminum ions from the AECs manufacturing process to stop corrosion.

Experimental Methodology

This article describes the experimental procedure for eliminating aluminum ions from the manufacturing of SMD Standard Aluminum Electrolytic Capacitor. The technique creates a very acidic environment that kills the aluminum ion bubbles by mixing aluminum hydroxide and aluminum sulfate in a slurry.

Results and Discussion

For many years, it has been difficult to get aluminum ions out of the aluminum electrolytic capacitor manufacturing process. The most popular methods for achieving this goal have been the employment of chemical additives and various cleaning techniques.

A novel technique, however, created by SRI International, relies on the dissociation of Al2O3 from the surface of High Voltage Solid Aluminum Electrolytic Capacitors using an acidic solution. This strategy might lower costs while enhancing capacitor performance.

The investigation, which is still in its early phases, was carried out on a small-scale prototype capacitor. However, if effective, this technique might emerge as a common strategy to eliminate aluminum ions from the manufacturing of aluminum electrolytic capacitors.

Conclusion

Aluminum ions can have a negative impact on the manufacturing processes of Low Leakage Solid Aluminum Electrolytic Capacitors, which are utilized in a range of electronic devices. This article describes a technique for eliminating these ions from the manufacturing process, which ought to enhance capacitance and dependability.
