WHAT IS CARD AND ASSEMBLY INSPECTION?

Card and assembly inspection is the process of checking whether the components on electronic circuit boards (PCBs) are correctly positioned, properly soldered, and whether the overall functionality of the circuit is maintained. This inspection is carried out during quality control on the production line, prototype testing, or in the mass production process.

Importance of Card and Assembly Inspection

1. Quality: Incorrectly placed or poorly soldered components can impair the functionality of the device or render it completely non-operational.
2. Reliability: Properly assembled and tested cards ensure the system operates reliably and stably over time.
3. Cost Control: Early detection of errors minimizes the costs associated with repairs after faults occur.
4. Compliance with Standards: Ensures compliance with international quality standards such as IPC, customer requirements, and industry standards.

Elements Checked in Card and Assembly Inspection

1. Correct placement and orientation of components
2. Soldering quality and absence of cold joints
3. Missing, incorrect, or reversed components
4. Manufacturing defects such as short circuits or cold solder joints
5. Mechanical damage, scratches, or broken traces
6. Relevant test steps (Electrical Test, Flying Probe Test, etc.)
7. Manual assembly checks
8. Conformal coating checks
9. Tests supported by devices like AOI (Automated Optical Inspection) and X-Ray
10. Specific checks for each board type
