Latest Patents

One of Trung H Nguyen's latest patents involves the etching of aluminum capacitor foil. This process is achieved by passing the foil through a bath of electrolyte while applying pulsed direct current. The pulse duration is designed to be at least nine times longer than the interval between pulses when the current falls to zero, ideally ranging from 3 to 27 milliseconds. The pulse current density is maintained between 2 to 10 A/in², with the etching temperature set between 50°C to 90°C. The electrolyte used is an aqueous solution containing sodium chloride and sodium sulfate. Another significant patent focuses on the preparation of capacitor electrodes. In this process, aluminum capacitor foil, initially etched for low-voltage applications, is anodized in two stages. The first stage utilizes an adipate electrolyte for low voltage, followed by a higher voltage stage in a borate electrolyte. This method ensures that the fine etch structure from the low-voltage etch remains intact during the higher voltage formation stage, making the foil suitable for intermediate to high-voltage capacitor applications.
