Annual maintenance of the circuit board
Jan 04,2019

⑴ clean up the dust on the circuit board.

⑵ The capacitance of electrolytic capacitors in the circuit board, if it is found that the capacity of electrolytic capacitors is less than 20% of the nominal capacity, should be replaced, the life of the general electrolytic capacitor should be replaced by about 10 years to ensure the performance of the circuit board.

⑶ For high-power devices coated with heat dissipation silicone grease, should check the thermal silicone grease has no dry solid, for dry solid should be dry solid heat silicone grease removed, coated with a new heat dissipation silicone grease, to prevent the circuit board in the high-power devices due to poor heat dissipation and burnout.
