Saki AOI Alternative: DaoAI vs Saki 3D AOI

DaoAI is an alternative to Saki's 3Di-EX 3D AOI: its machines build an inspection program from one verified golden board in 30 seconds to 5 minutes, without CAD files or a prebuilt component library, and its P5 and P5D inline 3D machines are available for delivery now. According to Saki's published materials, its 3D AOI uses automated program development tools and inspection program data standardized across SPI, pre-AOI, post-AOI and AXI.

At a glance: DaoAI vs Saki 3D AOI

DaoAI hardware figures are reference (typical) values from daoai.com, not guaranteed limits. Saki figures are as stated in its published materials. The clearance rows describe different machine types (DaoAI offline, Saki inline).

How does programming time compare?

Saki's current 3D AOI page describes automated inspection program development tools, and its 2025 announcements describe "One Programming" across platforms and AI that speeds inspection programming. Saki's 2018 release describes a Self-Programming workflow: "All you need is the Gerber and centroid CAD data," with components selected from its Golden Library and no golden board needed. Check with Saki which inputs the current 3Di-EX software uses.

DaoAI starts from a built board. The machine images one verified golden board, detects and models every component, draws inspection windows and sets thresholds. CAD or BOM data can be imported at any point to add designators and part numbers without losing tuning. A package the system has never seen is modelled from the board, so there is no library entry to create first.

The practical question is which input you have first. If boards often arrive before usable CAD data, or the data never comes, golden-board programming removes the wait. We cover this in AOI programming without CAD files.

How do they handle false calls after setup?

Saki says its AI combines supervised and unsupervised models with human judgment, and that its AI Solution automates defect judgment and character recognition. QD Analyzer adds data collection and analytics aimed at reducing false calls across the line.

DaoAI uses feedback learning at the machine. An operator marks a call as OK or NG, and an AI update retrains the model on that example instead of widening a threshold. Manual settings are kept, updates can be undone, and the line does not stop while it retrains. DaoAI states the false-call rate can reach about 1% after tuning; it depends on the board and process.

What does each system cover?

According to Saki, its current 3D AOI serves SMT and through-hole processes, including high-density boards with very small and tall components.

DaoAI covers 16 inspection capabilities across components, solder joints and leads, markings, barcodes (1D, QR and Data Matrix), through-hole joints and the whole board. The whole-board pass finds solder balls and foreign objects on bare laminate, outside any component window. Machines span offline 2D (P1, P1L, P2), inline 2D (P3, P3D), inline 3D (P5, P5D) and through-hole (A3), all on the same core software. See inspection coverage for the full list.

What drives total cost of ownership?

Over a machine's life, these usually cost more than the purchase price:

• Time to first good program. Include any wait for CAD data or library work.
• Library upkeep. A vendor library needs maintaining for new packages. DaoAI auto-programming does not require a prebuilt component library; presets and templates can be exported to other machines.
• Review labor. Count operator minutes per board on false calls during a trial.
• Upgrade path and software. Saki highlights upgradeable optical units on the 3Di-EX platform. On DaoAI, auto-programming, feedback learning, model training and offline operation are standard on every machine.
• Support. Ask where service engineers are based. DaoAI's engineering team is in Vancouver, BC.

How to evaluate DaoAI against Saki on your own boards

Run the same boards through both systems under the same conditions and record results side by side (see how to evaluate an AI AOI system before you buy):

1. Programming time. Measure from board arrival to a released program, including any wait for CAD data.
2. Detection. Use boards with known defects (missing, shifted, reversed, bridged, insufficient solder) and count escapes.
3. False-call review workload. Log operator review minutes per board over several hundred boards, before and after tuning.
4. 3D results. If height matters, measure the same components on both systems and note which metric each vendor quotes.
5. Repeatability. DaoAI's built-in Gauge R&R and Cpk analyze placement accuracy on X offset (mm), Y offset (mm) and rotation (degrees).
6. Data handling. Confirm where images and models are stored, remote access, and MES export format.

FAQ

Does Saki AOI need CAD data?

Saki's 2018 release describes self-programming from Gerber and centroid CAD data plus its Golden Library, without a golden board. Its newer materials describe automated programming tools and "One Programming"; check with Saki which inputs the current software requires.

Does DaoAI need CAD data?

No. DaoAI programs from one verified golden board in 30 seconds to 5 minutes, and auto-programming does not require a prebuilt component library. CAD or BOM data is optional and only adds designators, part numbers and grouping.

Can DaoAI inspect through-hole parts?

Yes. The A3 performs pre-wave and post-wave inspection in one machine, can inspect both sides of the board, and straddles the existing line. The P3 and P5 also support DIP/through-hole inspection.

Is DaoAI's inline 3D available now?

Yes. The P5 and P5D inline 3D machines are available for delivery now, with a 25 mm height measurement range (reference value).
