Solution to Welding Problem of Key Switch

Release Time:2019-04-18

 
Keyboard switches should be checked when problems arise, usually due to open welding. In this case, it is very important to do better repair welding, so the key switch repair welding also see our introduction, please have a detailed understanding.
When the key switch is repaired or repaired, it must be welded manually; when the repairman repairs the capacitor, it is not conductive, which is not beyond the precondition of the critical voltage (breakdown voltage) of the capacitor. Any substance is relatively insulated. When the voltage at both ends of the substance increases to a certain extent, the substance can conduct electricity. It's called breakdown voltage. Capacitance is no exception. After the capacitor is broken down, it is not an insulator, but in the middle school stage. Such voltage can not be seen in the circuit, so all the work below the breakdown voltage can be seen as an insulator.
Is it possible for us to solve the problem by ourselves, so that it can also be convenient for us and everyone?
