For the record, I would like to state that using water and a heat gun to clean electronics is perfectly safe! (as long as you know what you are doing). Please look into re-flow soldering (temperatures ramping up to around 210 C, and held for up to 120 seconds). Chances are you will realize that most PCB's (printed circuit boards) are washed after soldering to remove leftover water soluble flux from the PCB. The only prob with rinsing I see is using old water full of flux which causes shorts.
Water alone does not cause corrosion, but hydrogen atoms present in water can combine with other elements to form acids.
Never put any board in regular water, may still work for a few months, but will end causing cold solder joints and corrosion long term. Never put a harddrive in any any liquid.
I use (de-ionized) water to clean boards then use a hairdry first to dry off the board then a heatgun at low temps, then replaced all the capacitors with Japan 105c low ESR with long hours.

@orioncheung Ur lucky that it wont do any harm to most keyboards, as most are ribbontraced plastics that are sealed, only leaving the exposed carbon tracings for the keys, unless its a real expencive mobo with LCD/dot-matrix screens i dont see any problem with that method of cleaning them
@bloodreighn I dont use any LCD screen type keyboard. And yes I have open keyboards before and clean it. Tho, this logitech slim keyboard I have doesnt seem like to be open. So, what I do is I blast water on this keyboard. Then I use a towel and hair dryer to dry it. And I don't use that keyboard for weeks to month. And I use a spare KB. The reason I do this is because over time hard stuff get under the slim keys, making it hard to press. And I done this more than 5 times and it always works.
@bloodreighn Always could like to add. Like water cooling, When it leaks all over the video card and other parts. You try your best to try it up, use a fan and blow at it over night. And it should work fine the next day. I had this problem and my bro had this problem when we started doing water cooling. Over time plastic breaks and it leaks. All I am saying is. Make sure it is very dry, and no water in it before turning the pc back on. And if done right, it will work.
@savelkaunas I wouldnt say you fixed anything, but more than likley ( if any of them were working afterwards ) Seriously shorted there life span, Ever thought of what would happen if the Capacitors soaked up the water into there dilectric?? no matter how much heat you put on them without melting them will not get the water out and will short them out and kill the motherboard.
@bloodreighn it is very interesting how water can get inside the caps? BTW I repaired not 5 boards, but lots more. In fact, I receive lots of boards from recycle factory and all boards with cap problems are repaired. And still working fine.
Even ATX PSU, where higher voltages and it is quite difficult to dry transformer are working fine.
Better check what technology is used in China factories. Also, read datasheet of caps, whew thermal storage and soldering of the parts are described.
Best thing to wash with is low water isopropyl alcohol - I use 92% available at most drug stores. The electrolytics are mostly for voltage regulation for the CPU, hence why they are usually right near the CPU socket, the rest of the support circuits use chip caps that dont have a leakage problem. Also be sure to reclean the solder area of the solder rosin afterwards with alcohol to prevent corrosion of traces and leads. Savel is right - remove the battery since the board has voltage with it.
No. Removing battery you save chipset from electro chemical corrosion while washing and drying. The same problem if you drop mobile phone to water and don't remove battery- phone will dy even if it is working. Watter under chips will erode PCB tracks and vias.
So you're saying that if you don't take the battery out... water will get caught under the chips and corrode the tracks????
How well then can you guarentee that water WONT get trapped if you take the battery out... that's like saying you don't park the car on the right side of the driveway when it snows cause then you have to shovel the left side... when you just have to go out and shovel the right side anyway.
As I mentioned, if battery is not removed, current from it will corode PCB tracks during bath. After heating, all water is gone. But I think you'll not understand this- all your comments show that you didn't know anything...

I do this to my keyboard all the time. I hate sticky keys >.<. Remember to dry it read good before plugging it back in.

Wait till you really fuck a mobo up with all the junk that's in the water, they don't use Distilled water in the factory for good health.

do you have a video on how to identify and remove and replace bad caps? That would be most helpful.
ctrlaltdlt01 2 years ago
You must have/buy/build ESR meter to detect capacitor's hidden problems. Only some possible bad capacitors can be detected under visual inspection.
