A water droplet on a mobile device.
A water droplet on a mobile device.
I had an issue when water accidentally splashed near my PC. A few tiny droplets were seen on the motherboard (the black dots were similar in size and position). The computer was off when this happened. I took out the power supply connector, used a cotton swab to clean it up, and it dried easily. I left the PC for a day thinking about drying. Could these droplets cause major problems like the computer failing to turn on or developing issues over time? Thanks in advance for your help—I know my PC tends to gather dust on the floor.
When it appears and feels dry, there should be no problems involved.
Not necessary even a single day. The exact time depends on where the water is but usually you can clean it by wiping or soaking with a paper towel, rubbing the affected area with alcohol and letting it dry. Once the alcohol is gone, it's good to go. If it touches a part or heat sink, you may need more action but the PCB is sealed so water can't reach the circuitry—issues usually appear when a connection is bridged between components. For serious concerns, place the board under a fan for a few hours or overnight; this will help resolve the issue.
Typically, they follow a standard coating process. I’ve soaked several in the dishwasher, achieving good outcomes after thorough cleaning and drying, often getting them ready again within a few hours. I usually let them dry overnight, but I can rush the process if needed.
On the PCB surface, it's generally fine. However, if components connect across the board, that can cause issues. There may also be exposed areas where parts are soldered, which could be problematic. These spots often show solder marks but no actual connections. Sometimes they serve as measurement points for testing the board.
It's strange why water cleaning works but I still face problems like broken boards that should function. Sometimes VRMs just decide to short out on their own, which is frustrating. The AM and socket parts are often damaged, forcing me to remove the cover and deal with the mess. These boards usually have poor Foxconn design instead of the more reliable lotes models that let you pull the lever back without damage. I really want a better solution since these issues are really annoying. For now, the only options seem to be forex trading and crypto, but that's about it.
