PCB circuit board is based on the insulation board as a substrate, cut into a certain size, which at least with a conductive pattern, and cloth with holes (such as component holes, fastening holes, metal holes, etc.), used to replace the previous device electronics Components of the chassis, and to achieve the interconnection between electronic components. PCB board from the single layer to the development of double-sided panels, multilayer and flexible board, and continue to high-precision, high density and high reliability direction, the more widely used.
PCB circuit board maintenance knowledge
1, the annual maintenance knowledge:
1. Clean the dust on the circuit board.
2. Check the electrolytic capacitor capacity in the circuit board. If the capacity of the electrolytic capacitor is less than 20% of the nominal capacity, it should be replaced. The life of the electrolytic capacitor should be changed for about ten years to ensure that the pcb circuit board The work performance.
3. For high-power devices coated with heat dissipative grease, you should check whether the heat dissipating silicone grease is dry. For dry solids, remove the dry heat grease and apply a new heat grease to prevent the circuit board In the high-power devices due to poor heat and burned.
2, season maintenance:
1. Clean the dust on the circuit board on a quarterly basis, and use the cleaning solution for the circuit board for cleaning. After cleaning the dust, use the blower to dry the circuit board.
2. Observation of the circuit in the electronic components have not been traces of high temperature, electrolytic capacitors have no signs of leakage, if any should be replaced.
