The circuit board should be regularly maintained during use
08 Jan,2025
The circuit board should be regularly maintained during use to ensure that it operates in good condition and reduce the failure rate of the circuit board. The maintenance of circuit boards in use can be divided into the following situations:
1. Half maintenance:
⑴ Clean the dust on the circuit board every quarter, using circuit board specific cleaning solution. After cleaning the dust on the circuit board, use a hair dryer to dry it.
⑵ Observe whether there are traces of high temperature on the electronic components in the circuit, and whether the electrolytic capacitors have bulged and leaked. If there are any, they should be replaced.
2. Annual maintenance:
⑴ Clean the dust on the circuit board.
⑵ Conduct random checks on the capacity of electrolytic capacitors in the circuit board. If the capacity of the electrolytic capacitor is found to be less than 20% of the nominal capacity, it should be replaced. Generally, electrolytic capacitors should be replaced after a lifespan of about ten years to ensure the performance of the circuit board.
For high-power devices coated with heat dissipation silicone grease, it is necessary to check whether the heat dissipation silicone grease is dry and solid. For those that are dry and solid, the dry and solid heat dissipation silicone grease should be removed before applying new heat dissipation silicone grease to prevent the high-power devices in the circuit board from being burned out due to poor heat dissipation.
