7 Essential Tips for AOI PCB Inspection

### Preparation before Inspection.

1. **Prepare Inspection Equipment:** Ensure that the AOI inspection machine is properly set up and calibrated before starting the inspection process.

2. **Check PCB Layout:** Verify that the PCB layout matches the design file to avoid any discrepancies during inspection.

### During Inspection.

3. **Start with a Test Run:** Conduct a test run to ensure that the AOI machine is functioning correctly and capturing defects accurately.

4. **Set Inspection Parameters:** Adjust the inspection parameters according to the specific requirements of the PCB being inspected to minimize false positives or false negatives.

5. **Analyze Inspection Results:** Carefully review the inspection results to identify any defects or anomalies on the PCB.

### After Inspection.

6. **Document Inspection Findings:** Record all inspection findings, including detected defects, false calls, and any necessary rework or repairs.

7. **Implement Process Improvements:** Use the insights gained from the inspection process to make necessary adjustments to the PCB manufacturing and inspection processes for future improvements.

Following these essential tips for AOI PCB inspection will help ensure that the inspection process is thorough, accurate, and efficient. By taking the time to properly prepare, conduct, and analyze the inspection, manufacturers can minimize defects, reduce rework, and improve overall product quality.
