I have recently spilled a little bit of water on one of my GTX 260 cards. I thought I got all of the water dried, but when I turned it on it sparked and smelled like burnt electronics. I was wondering if it might be possible to repair this maybe with solder just to bridge the connection. Any help would be appreciated.
This is why you are supposed to blast any at wet parts. This is also why I won't use any thing but distilled water as it does not contain conductive substances unlike most cooling solutions which can be corrosive in some formulas. I have seen blocks that simply have been eaten through by the solutions that are sold online and with the kits. I have spilled water on parts before and once ware a board took a big spill of 1L of tap water but still ran long enough for a proper shutdown. What you should have done if it were a solution was to wash the card in water then use a can of high pressure air to blast away any water under any of the components. When you think that it is dry think again there is a lot of water hiding under just about every thing there. Why do this is simple most solutions contain mildly conductive substances to improve heat absorption and dissipation. Getting rid of it is key to salvaging any part from a spill even from beverages. Tackle it fast before it dries and is allowed to set or you will have cases like this ware permanent failure is a result or corrosion east away at the board and bonds.
