3D-CT AXI

The industry’s fastest speed for inline inspection

An new, innovative larger detector for wide-area imaging results in fewer required FOVs and reduced takt time. When combined with Saki’s unique optimized software, imaging and calculation processing are completed almost simultaneously, producing the ultra-low cycle time required for efficient inline X-ray inspection.

High-definition 3D images

Saki’s unique Planar CT technology specializes in flat object imaging, instantaneously generating hundreds of high-definition tomographic images that are stiched together to create high-definition 3D data.

Saki’s high-precision hardware design is essential for the creation of high-definition 3D data. The ultra-rigid gantry and high-resolution linear scale provide incredible accuracy in positioning for stable imaging. Gantry position information is reflected in real-time calculations to obtain high-definition 3D images with clear edges.

High-precision correction technology

Generating high-definition 3D imagery requires high-precision correction technology. Saki’s 3D-AXI utilizes pattern data, an automatic board warp correction function in the XYZ directions, and a positioning function for improving inspection accuracy and to reduce the burden of creating inspection programs.
Seamless high-definition 3D data is acquired through a process that includes XYZ directional correction for each pixel combined with the 3D-AXI ‘One Piece’ function for connecting FOVs.

By combining high-precision imaging, correction, and calculation processing, it is possible to acquire dense 3D data based on the information in the X, Y and Z-axes – this ensures that defects are not overlooked at any height.

All inspections meet, or exceed, IPC standards.

Supports inspection of Slim and lightweight DSC power module

By selecting X-ray tube with a maximum output of 130kV, it is also possible to inspect thin power modules.
The range of inspection objects expands from DSC power modules, chiplets, elements with aluminum cooling fins, to boards with transformers on the backside.
Not only does it improve penetration power, but it also improves brightness, shortening exposure times, and contributing to improved scanning speed. (Compared to standard tubes: Approx. 40% shorter)

Slim and lightweight DSC power module

Saki’s 3Xi-M110 can clearly separate multi-layer components, such as spacers from multiple solder layers and also detect void defects.

Easy programming

Inspection programs on conventional X-ray inspection machines can be difficult to create – in contrast, Saki’s X-ray inspection machines are able to draw from existing AOI programming data.
Programming time is significantly reduced by using pre-existing design data and by automatically setting imaging conditions, such as setting magnification for each FOV.
Additionally, parts that span multiple FOVs can be connected and saved as single-component 3D data for improved library management and reduced man-hours.

Debugging without halting the production line

The offline debugging function enables the collection and debugging of images without stopping the operating equipment. Alongside real-time library updates, a catalogue of historic defect data is saved and can be re-inspected, significantly contributing to overall quality assurance.

Advantages of cooperation with AOI

For ease of operability, Saki’s 3D-AXI inspection machine runs on the same software platform as its AOI. Achieving consistent quality control on the line, inspection results are integrated using both AOI and AXI – with results for each station displayed on the same screen. By sharing board ID information with the AOI, there is no need for intermediate conveyors or barcode readers, saving space and cost.

Future-proof hardware design

Highly-durable hardware is essential to perform advanced inspections while maintaining stable accuracy in inline, long-term high-volume production environments. Saki’s X-ray inspection machine has a unique highly-rigid gantry that achieves long equipment life and high repeatability.

Self-diagnostic functions

Sustaining high-precision, high-accuracy inspection is important to maintain high productivity. Saki’s X-ray inspection equipment regularly diagnoses the deterioration of the X-ray source, uneven image brightness, frame distortion, and more. Maintenance can be carried out in a planned manner and high-accuracy can be maintained. Self-diagnosis prevents sudden equipment failure, reduces equipment downtime, prevents unnecessary replacement of non-defective parts, and reduces maintenance man-hours.

X-ray dosage simulator

When performing X-ray inspections, many people are concerned about the risk of component failure due to radiation exposure. Saki’s X-ray inspection equipment is equipped with an exposure dose simulator, predicting the exposure dose for each area to optimize imaging conditions. X-rays are irradiated only during imaging, minimizing irradiation.
