In the use of circuit boards, it should be maintained regularly to ensure that the circuit board works in a good state and reduce the failure rate of the circuit board. The maintenance of the circuit board in use is as follows: 1. Maintenance of half a year: ⑴ Clean dust on the circuit board every quarter. You can use the special cleaning solution of the circuit board to clean it. The circuit board can be dried. Observe that the electronic components in the circuit have no traces of high temperature, and the electrolytic capacitance has no leakage. If any, it should be replaced. 2. Annual maintenance: ⑴ Clean the dust on the circuit board. Sample the capacity of electrolytic containers in the circuit board. If the capacity of electrolytic capacitors is found to be less than 20%of the nominal capacity, it should be replaced. Generally, the life of the electrolytic capacitance should be replaced for about ten years performance. For high -power devices with heat dissipation silicon grease, it should be checked whether the heat dissipation silicon grease should be solid. For dry solids, the dry solid heat dissipation silicon grease should be removed and applying a new heat dissipation silicon grease to prevent the circuit board from in the circuit board to prevent the circuit board from in the circuit board The high -power device is burned out due to poor heat dissipation.
