How to Replace Ceramic Capacitors
Capacitors are electronic components that store an electrical charge. Capacitors are made up of two conductors, or leads and an insulator. In circuits, capacitors are usually used for blocking direct currents, while letting alternating current pass. Capacitors come in many different shapes, sizes and values, which are measured in farads. One type of capacitor is a ceramic capacitor. Ceramic capacitors are typically small capacitors with lower values that are made of layers of metal and a ceramic material that serves as the insulator.

1
Isolate and identify the ceramic capacitor you want to replace on the circuit board. Remove the circuit board from its device and place it on a work bench if need be.
-
2
Discharge the old capacitor by either laying a screwdriver across the two leads or by touching the two capacitor leads with the ends of a resistor.

3
Heat up the soldering iron and melt the old solder contacts on the back of the circuit board. Use a solder sucker to suck out the old solder. Pull out the old ceramic capacitor by hand.

4
Slide the new ceramic capacitor into the circuit board connection holes. Place the end of the solder to the lead and touch it with the tip of the soldering iron. Allow the solder to melt the leads to the circuit board.
