When an SSD is exposed to liquid, galvanic corrosion rapidly eats away at the PCB's copper ground planes and destroys the protective solder mask layer. Left unchecked, this corrosion creates conductive mineral bridges that cause massive electrical shorts across the board, pulling critical data and power rails down to ground and rendering the drive completely dead.
Within the clean room, engineers submerge the PCB in an ultrasonic chemical bath to lift and dissolve oxidized scaling without harming delicate silicon components. Under high optical magnification, technicians gently scrape away the remaining compromised copper down to a clean, conductive base. The damaged ground sections are reconstructed using high-purity copper foil or liquid silver conductive paint. Once structural and electrical integrity is verified with digital multi-meters, engineers apply a fresh layer of UV-curable green solder mask. This completely seals the repaired circuitry, shielding the traces from environmental exposure and stabilizing the drive for raw data extraction.
