Challenge & Solution

3D Inspection for Hidden BGA / QFN Solder Joints

ChallengeTraditional 2D optical inspection cannot see through the package blind spot, forcing reliance on sampled X-ray — costly, slow, and limited in coverage.

Solution3D AI-AOI imaging sees through the package blind spot; X-ray is reserved only for difficult-case review, cutting inspection cost and time significantly.

FAQ

What's the biggest challenge in 3D Inspection for Hidden BGA / QFN Solder Joints?

Traditional 2D optical inspection cannot see through the package blind spot, forcing reliance on sampled X-ray — costly, slow, and limited in coverage.

How does DaoAI solve this?

3D AI-AOI imaging sees through the package blind spot; X-ray is reserved only for difficult-case review, cutting inspection cost and time significantly.

What results can this deliver?

In real production deployments, Overall detection rate reaches 99%+, Downstream defect-rate reduction reaches -80%, and Detection rate gain (70%→99%) reaches +30pp (case studies are simulated scenarios based on real product capabilities; see product pages for official benchmarks).

How much does 3D Inspection for Hidden BGA / QFN Solder Joints typically cost?

3D Inspection for Hidden BGA / QFN Solder Joints pricing depends on production-line scale, number of inspection points, and deployment mode (cloud/edge/on-premise); configurations vary significantly by customer, so we don't publish a fixed price list.
