To clean a circuit board with a leaking capacitor, first disconnect the device from any power source. If the device has a large amount of voltage stored in its capacitors, discharge the capacitors with a capacitor discharge tool before cleaning. Then, remove the damaged circuit board from the device.
To remove a burst capacitor from a circuit board, cut the leads attaching it with wire clippers and discard them. Brush away any dry or loose capacitor electrolyte from the circuit board with a toothbrush. Apply a small amount of isopropyl alcohol to the end of a cotton swab and wipe any remaining capacitor electrolyte from the circuit board.
To remove a capacitor from an electronic circuit, first, take out the circuit (motherboard) so you can access it with a soldering iron. Identify the capacitor's legs and clip off the leg until there are 2-3 millimeters left. Capacitors, like batteries, have a “+” and “-” insertion point.
Circuit boards can be cleaned even after a capacitor leakage issue. Capacitors are an essential part of any circuit board. They store up and release electrical charge, while also blocking certain kinds of current and allowing others to pass.
Filter capacitors tend not to be too picky about their values, provided they can reduce the supply ripple to a level that the electronics can handle. If it's connected next to an IC, google the IC's part number and see if you can find an application note, or a usage example. Many datasheets have this information.
