2. These boards are used to replace the previous electronics chassis of components and facilitate interconnection between electronic components.
3. Over time, PCB boards have evolved from single-sided to double-sided, multilayer, and flexible PCBs.
4. They are continuously progressing towards higher precision, density, and reliability, and their applications are expanding.
The following I will introduce maintenance knowledge of PCB circuit boards:
A. Annual maintenance knowledge:
1. Clean the dust on the PCB board regularly.
2. Conduct sampling inspection on the electrolytic capacitor capacity in the PCB board. If the capacity is less than 20% of the nominal capacity, replace it. Typically, electrolytic capacitors should be replaced after ten years of service to ensure the performance of the PCB circuit.
3. For high-power devices coated with heat-dissipating grease, check for dryness. If dry, remove and apply new grease to prevent overheating and potential damage to the circuit board.
B. Seasonal maintenance:
1. Clean the dust on the PCB circuit board every quarter using a special cleaning fluid. Use a blower to dry the board after cleaning.
2. Check electronic components for signs of high temperature and electrolytic capacitors for bulging or leaking. Replace any components showing these signs.
