There are many kinds of circuit board damage, and whether it can be repaired depends on the specific damage mode. But it can be repaired in most cases. This paper will introduce several cases of circuit board damage and their maintenance methods.

Component damage

There are many kinds of electronic components on the circuit board. Sometimes in use, a component may be damaged and the function of the product may be problematic. This kind is best repaired, just replace the components, but you need to find the faulty components with the help of auxiliary tools.

Circuit board water inflow

It is also a very easy problem for water to invade the circuit board. This situation is easier to maintain if the water does not pass through electricity after entering the water. Clean the water. If the power is turned on after the water enters, some components may be burnt out, which will increase the difficulty of maintenance.

The circuit board was burned.

If the situation is serious (such as short circuit), a large piece of components may be burned out, or even the circuit board may be burned through. In this case, replacing the circuit board may be the best choice. In maintenance, this situation is also the most difficult and profitable, such as replacing the motherboard.
