Rubber is too brittle to hold corrosive liquid but do they use it? I don't know the manufacturers of the electrolytic capacitors in my devices, I have cartridge consoles from the early 90s, Philco and Toshiba CRT TVs from the early 2000s, PS2 slim 90000, and the most recent ones are TVBOX T95 Max Plus, power supply Chinese 5 and 12v, asus sata dvd drives all these devices use electrolytic capacitors and are stored...

In the long-term storage of electronic devices, does the leakage of acid from the aluminum electrolytic capacitor that corrodes the PCB occur because the protective layers have been slowly corroded over the years and opened to release the acid in board?...

there a risk of this aluminum electrolytic capacitor of electronic device long term storage opening and leaking acid and corroding the PCB board?
