How to Choose an AOI Inspection Machine

Selecting the right AOI ensures you catch defects without slowing production. Here is how to choose an AOI inspection machine using five key criteria. SMTFullLine offers a range of AOI systems and free consultation.

1. Determine Your Production Volume

• Low volume / prototyping – Offline AOI (manual load) is sufficient and cost‑effective.

• Medium to high volume – Inline AOI with automatic conveyor integration.

2. Identify Critical Defects to Catch

• Simple boards (0603 and larger) – 2D AOI works well.

• Fine‑pitch, BGAs, QFNs – 3D AOI needed for height measurement and lifted leads.

3. Balance Speed and Accuracy

• Higher resolution cameras (12MP+) increase inspection time. Select a model that can keep up with your pick‑and‑place machine output.

4. Consider Software and Ease of Use

• Look for offline programming to create inspection programs without stopping production.

• User interface should show defect images clearly.

5. Check Support and Spare Parts

• Ensure the supplier offers training, software updates, and replacement parts.

How SMTFullLine Simplifies Your Choice

We ask you about your board mix, volume, and budget, then recommend one or two AOI models that fit. We can also send sample inspection reports for your boards.
