Testing and Inspection Methods in PCBA Manufacturing
Why Is PCBA Testing & Inspection Important?
During PCBA production, defects like solder bridges, missing components, open circuits, and misalignments can occur. Without proper testing and quality control, these defects can lead to:
⚠️ Product malfunctions and failures
⚠️ Increased return rates and warranty costs
⚠️ Reduced lifespan of electronic devices
⚠️ Safety risks in critical applications (automotive, medical, aerospace)
Industries such as consumer electronics, telecommunications, automotive, and medical devices rely on rigorous PCBA testing to ensure long-term performance, safety, and compliance with international standards.
Common PCBA Testing & Inspection Methods
To guarantee PCB assembly quality, manufacturers use a combination of automated and manual inspection techniques.
1. Automated Optical Inspection (AOI)
AOI is a widely used, non-contact visual inspection method that scans PCBAs using high-resolution cameras and AI-based algorithms to detect:
✅ Soldering defects (cold solder joints, solder bridges)
✅ Component misplacement or polarity errors
✅ Missing or misaligned components
✅ PCB surface defects (scratches, contamination, or cracks)
