Saki Introduces Inline 3D-CT Automated X-ray Inspection Machine for PCBs

Saki Corporation, a leading provider of automated optical and X-ray inspection and measurement equipments for PCBs, has released a new compact, lightweight, inline 3D-CT automated X-ray inspection machine, the 3Xi-M110. It reduces the dose and exposure to X-rays during inspection and features new soldering quality inspection functions for PCB assembly applications.

In the automotive and communications industries, where quality assurance is important, the effectiveness of high-precision, high-quality PCB X-ray inspection has become critical. Saki’s new X-ray inspection system ensures the quality of hidden solder joints for bottom-electrode packages, such as BGAs, LGAs, and QFNs, which are found in advanced embedded devices, telecommunications, and automotive products. Saki's Planar Computed Tomography (PCT) provides precise volumetric measurements and shape reconstruction to find voids, head-in-pillow (HiP), and other defects that are extremely difficult to identify.

The 3Xi-M110 hardware platform is 1,380mm wide and weighs 3,100kg, making it 40% lighter and reducing its footprint by 25% over its predecessor. Manufacturing floor-space is saved, it’s easy to install, and production-line operation is significantly improved. Although the cast iron frame is lighter in weight, it maintains the rigidity needed for stable operation and accuracy, while the imaging range has been optimized to handle board sizes up to 360 x 330mm (W x L). For larger 360 x 510mm (W x L) boards, 2-step image capture is available.

The new system delivers exceptional speed and accuracy by utilizing a double motor-driven system equipped with a high-precision linear scale manufactured by Magnescale Co., Ltd. to optimize power and precision. Saki’s enhanced PCT technology algorithm improves image capture speed by 30%, reducing production-line takt time (maximum amount of time in which a product needs to be produced in order to satisfy customer demand).

One of the most significant features of the new system is Saki’s revolutionary X-ray tube, which can reduce X-ray exposure up to 70% by powering on the X-rays only at the moment of image capture. An exposure dose simulator allows the user to monitor the radiation dose. Based on that information, the method and magnification for releasing the X-rays can be set. The new X-ray tube design does not require periodic maintenance or spare parts, and the built-in monitoring system reports when the tube needs replacing.

Saki will demonstrate the PCB inspection capabilities of the 3Xi-M110 at productronica 2019 (#Stand A2.259) scheduled from 12th to 15th November in Munich, Germany.
