Saki’s unique Line Scanning Technology for 2D-AOI provides high speed and high accuracy inspection.
(this looks like the same message as the point above)
High speed inspection with Line Scanning Technology
Saki’s unique and proprietary Line Scanning System inspects an entire PCB 'on-the-fly' in just one pass. The system projects multiple lights at different angles onto the substrate obtaining high resolution images in one scanning operation. The system is faster than FOV based technologies, for example, a 330 x 330 mm (13" x 13") PCB is inspected in ten seconds.

Saki's design includes a full inspection library, unique optical design, and full coaxial overhead lighting
Saki's 2D AOI systems include a large telecentric lens to capture the clearest images with no blind spots. The system corrects for brightness of the entire sample and compensates for position misalignment in real time while the image is scanned, assuring inspection results that are accurate, reliable, and repeatable over time. A variety of algorithms and lighting types are available to support a wide range of industry inspection requirements.
High productivity realized with the simple uniaxial hardware
The uniaxial hardware design delivers a highly durable, vibration-less, and industry-leading minimum footprint of W:600 mm / 24in. Some customers report using them for more than ten years.
Dual lane, large board, simultaneous inspection, multi-core CPU, and proprietary hardware design support a broad range of allications.
Simultaneous double-sided inspection
With its dual side capability the system inspects both sides of the PCB, SMT and through-hole, at the same time eliminating the need of an inverting conveyor. This capability prevents potential damage by inverting the PCB, reduces line length, eliminates conveyor cost, and maximizes floorspace output. The system also supports selective soldering and conformal coating processes.
Simultaneous double-sided scanning
Conformal coating inspection with UV light
Saki’s design with UV light capability supports your conformal coating process coated and uncoated surfaces and scatter.

Uniform brightness capability addresses shading concerns
Saki's digital shading compensation corrects luminance in real time during scanning to avoid uneven brightness and aberrations within the pixels. Used in combination with our multiple lighting systems, uneven brightness is corrected and image distortion is eliminated. The result is superior reproducibility, reliability, consistency, and compatibility between machines.
Saving full images supports traceability
The system scans and images the entire PCB just once, and inspection data is easily recalled to support traceability requirements.
Full surface imaging
The Extra Component Detection function to detect foreign material (2D)
With its full board imaging technology the system provides Extra Component Detection (ECD) easily identifiying components droped by the placement machine.
ECD NG Images
Multiple lighting and algorithm classifications
Defects are easily classified from a list of twenty kinds of inspection images which are created by combining top, side and low side images.
Character recognition with unique lighting
Polarity and character recognition is easily supported with Saki's proprietary lighting with automatic brightness capability

Support of selective soldering processes
Saki’s special-purpose algorithms support through-hole solder inspection in a single step. The system simultaneously inspects copper exposure, pin-holes, missing pins, solder shape, and bridges.
