Heat sink: Used to control equipment temperature and ensure that semiconductor chips and other components are operating within normal operating ranges. If the radiator is damaged or less efficient, it may need to be replaced.
Connectors and cables: The electrical connectors and cables that connect the internal and external components of the device may need to be replaced due to wear or damage.
Filters and capacitors: Used to protect circuits from electrical noise and interference, as well as to smooth power fluctuations. These components may need to be replaced due to aging or damage.
Sensors and monitoring equipment: used to monitor the operating status and parameters of the equipment, such as temperature sensors, pressure sensors, etc. These sensors may need to be replaced due to failure or beyond their useful life.
Control board: As the control center of the device, the control board is responsible for managing and performing various operations. If the board fails, it may be necessary to replace the entire board or specific parts of it.
