Quality Control of PCB Board Assembly:
1. Visual Inspections: Engineers and operators often perform visual inspections to ensure that components are installed correctly and that there are no obvious defects such as soldering issues, component misalignment, etc.
2. X-ray inspection: X-ray inspection can be used to check for soldering problems hidden under components, especially high-density components such as BGA (Ball Grid Array).
3. Automated Optical Inspection (AOI): AOI systems use cameras and image processing software to inspect solder quality and component placement on PCB boards. Problems can be found quickly and detection efficiency can be improved.
4. Infrared welding inspection: Infrared welding inspection can detect welding temperature and solder joint quality to ensure correct welding.
5. Functional Testing: Functional testing is a method of verifying that an electronic device is working as expected by connecting it to a power source and running a predefined test program. This can detect electrical issues as well as performance issues.
6. Electrical testing: Electrical testing can verify the electrical performance of electronic devices by measuring parameters such as resistance, capacitance, and voltage of circuits.
