1. Physical Inspection: Inspection of PCBA appearance, including soldering quality, component mounting position, protective measures, and so on. Ensure that the assembly quality and appearance of the PCBA meets the expected requirements.
2. Electrical Testing: Verify that the electrical performance of the PCBA meets the specifications by performing electrical testing on specific circuits, components or interfaces. For example, conduct connectivity test, power test, power consumption test, etc..
3.
Functional testing: According to the functional requirements of the PCBA, conduct comprehensive functional testing to ensure that each circuit and component functions properly. This may involve specific circuit signaling tests, communication interface tests, sensor tests, etc.
4. Welding quality assessment: Check the quality of welding, including the firmness of the solder joint connection, welding defects (e.g., cold welding, welding balls, etc.) and whether the welding parameters meet the requirements.
5. Component verification: Verify that the components used on the PCBA meet the requirements, including confirming that the source, batch, and specifications of the components match the design requirements.
6. Temperature testing: Evaluate the performance stability and reliability of the PCBA under specific temperature or temperature cycling conditions.
7. Testing records and reports: Detailed records of each testing step, and generate the corresponding test report, including test results, anomalies and problem solving measures.
