The Electric Circuit Board should be serviced regularly to ensure that the
electric circuit board is in good working order and reduces board failure rates.
Electric Circuit Board Assembly Manufacturer would like to share with you the
maintenance of the board in use. It is divided into the following cases:
Electric Circuit Board
1. Half maintenance
快乐三张牌下载官方①Clean the dust on the electric circuit board every quarter, and clean it with the special cleaning liquid of the circuit board. After the dust on the circuit board is cleaned, blow the circuit board with a hair dryer.
快乐三张牌下载官方②Observe that the electronic components in the circuit have not passed the trace of high temperature, and the electrolytic capacitor has not swelled and leaked, and should be replaced if necessary.
2. Annual maintenance
①Clean the dust on the board.
②Sampling the capacity of the electrolytic capacitor in the circuit board. If the capacity of the electrolytic capacitor is less than 20% of the nominal capacity, it should be replaced. Generally, the life of the electrolytic capacitor should be replaced after working for about ten years to ensure the operation of the circuit board.
③For high-power devices coated with heat-dissipating silicone grease, check whether the heat-dissipating silicone grease is dry. For dry-drying, the dry heat-dissipating grease should be removed and coated with new heat-dissipating grease to prevent the board from being damaged. The high-power devices burn out due to poor heat dissipation.
