During the PCBA patch production process, PCBA boards may have poor quality due to improper operation by production personnel or poor material quality. In such cases, the bad PCBA board needs to be repaired.

The process of PCBA patch maintenance involves the following steps:

1. Check PCBA: Make sure the PCBA patch has no obvious defects such as short circuits, air welding, missing parts, extreme reverse parts, burnt parts, etc.

2. Power test: The main function of the power supply test is to check if there is a short circuit.

3. Measure all power: Use the test fixture double-check to measure the power after power on.

4. Repair according to the bad phenomenon: Refer to the maintenance work guidance provided by the project and repair the defects in combination with the circuit maintenance principle.

5. Self-check after repair: After maintenance, the maintenance parts need to be self-checked. The main inspections include short circuits, empty solder, tin slag, and solder joint appearance.

6. Test tool test: Use the test tool to check whether the PCBA patch is repaired normally.

7. Conduct a comprehensive inspection of the repaired product: By maintaining the bad PCBA patch, not only can the waste of the board be reduced, but also the production cost of the PCB factory can be reduced.

The tools required for PCBA patch maintenance include an oscilloscope, digital instrument, thermostatic iron, hot air gun, needle nose, diagonal pliers, and tweezers. By following these steps and using the necessary tools, you can ensure the repair of PCBA boards and reduce production costs for the PCB factory.
