Common Reasons Circuit Boards Fail

Circuit boards are perhaps one of the most important components of electronics. They fail for a variety of reasons. Understanding these will make it easier for you to schedule a circuit board repair.

Burnt Components

Unfortunately, if a circuit board is exposed to high temperatures, they can burn. In some instances, it is as a result of insufficient space inside of the unit. Additionally, some boards are built stronger than others, allowing them to handle more or less heat.

Environmental Factors

If your circuit board has been exposed to various components in the environment, it can cause a malfunction. For example, if the board gets wet, it may cause the board itself to warp. There may also be damage to the soldering joints.


In some instances, boards need to be repaired because they are old. In some instances, it is simply because of a burnt component. However, there may be deep-rooted issues that need to be determined by a technician. You will be able to talk to a technician in order to determine whether you will be able to fix the existing PCB or if it will be necessary for you to replace the board or even have it rebuilt.

Poor Manufacturing

Another reason that a circuit board may fail is because it was poorly manufactured to begin with. You may be able to identify these issues because of leftover flux or even loose components. In some instances, a technician will be able to go back through and solder in order to connect joints and make improvements to the overall construction.

By understanding more about what a circuit board can handle, you can work to keep it in the best condition possible. When the board does fail, you will need to have a trusted technician to turn to for a repair.
