Saki Corporation’s Compact, Lightweight, Inline 3D-CT Automated X-ray Inspection System for PCBAs Delivers Increased Speed, Accuracy, and Safety

Saki showcases automated inspection solutions for ensuring soldering quality at productronica 2019, Stand A2.259

GHTokyo, Japan – 31 October 2019 – Saki Corporation, an innovator in the field of automated optical and X-ray inspection and measurement equipment, introduces a compact, lightweight, inline 3D-CT automated X-ray inspection machine, the 3Xi-M110, for inspection of printed circuit board assemblies (PCBAs). The 3Xi-M110 reduces the dose and exposure to X-rays during inspection and features new soldering quality inspection functions for PCB assembly applications. Saki will demonstrate the PCB inspection capabilities of the 3Xi-M110 at productronica 2019, being held in Munich, Germany from November 12-15, in stand A2.259.
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 floorspace 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 3Xi-M110 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.
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.
“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,” said Masahide Iino, director and head of the sales division of Saki Corporation. “Saki will continue to respond to the needs of the market by leveraging the accumulated knowledge and experience it has gained through its history as a leading innovator in the field of 2D/3D automated optical inspection and X-ray inspection.”

TE Connectivity Announced Ultra Small Spring Fingers

TE Connectivity (TE)’snew ultra small spring fingers have one of the smallest footprints in the market to save valuable PCB space, allowing for use in a broad range of applications with space constraints across various industries.TE’s ultra small spring fingerscan save valuable PCB space with one of the smallest footprints in the market. Closed-loop contact design ensures reliable connection to the PCB, better normal force and higher current capacity (1.5A). Robust side wall minimizes over- compression. Special anti-lifting design can improve assembly e ciency by locking the tip of the contact within the sidewall of the spring  nger, which helps prevent the contact from getting caught on an operator’s glove during assembly. Pick-and-place area supports auto-assembly processes. It also offered in different heights and styles.As an authorized distributor for TE Connectivity, Heilind Asia provides TE’s products and also value added services. Heilind Asia supports both original equipment …
