PCB circuit board specific cleaning solution can be used for cleaning. After cleaning the dust on the double-sided circuit board, use a hair dryer to dry the double-sided circuit board.

Because circuit boards generally contain electronic components, it is not suitable to clean them with water. Instead, specialized board cleaning solutions such as hydrogen peroxide or thinner should be used for better cleaning, especially for better oxidation removal.

Clean with anhydrous alcohol and acetone, please pay attention to ventilation and wear rubber gloves. Alcohol can cause unsightly white marks and affect the appearance when it comes into contact with rosin anti-corrosion coating or solder residue.

The circuit board should be regularly maintained during use to ensure that it operates in excellent condition and reduce the failure rate of the circuit board. There are several maintenance conditions for circuit boards in use:

1. Half maintenance:

⑴ Clean the dust on the PCB board every quarter, using a dedicated cleaning solution for the circuit board. After cleaning the dust on the circuit board, use a hair dryer to dry it.

⑵ Investigate whether there are traces of high temperature on electronic components in the circuit, and whether there is leakage in electrolytic capacitors. If so, replace them.

2. Annual maintenance:

⑴ Clean up 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 capacitors is found to be less than 20% of the nominal capacity, they should be replaced. Generally, electrolytic capacitors should be replaced after about ten years of operation to ensure the operational 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 and a new one should be applied to prevent the high-power devices in the circuit board from burning out due to poor heat dissipation.
