Saki Introduces 3D Automated X-Ray Inspection Machine


Reading time ( words)

Saki Corporation has launched an 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 soldering quality inspection functions for PCB assembly applications. Saki will demonstrate the PCB inspection capabilities of the 3Xi-M110 at productronica 2019 in Munich, Germany, November 12-15, in stand A2.259.

Saki’s X-ray inspection system is intended to ensure 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 volumetric measurements and shape reconstruction to find voids, head-in-pillow (HiP), and other defects that are difficult to identify.

The 3Xi-M110 hardware platform is 1,380mm wide and weighs 3,100kg. 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, two-step image capture is available.

The 3Xi-M110 delivers speed and accuracy by utilizing a double motor-driven system equipped with a linear scale manufactured by Magnescale Co. to optimize power and precision.

One of the features of the new system is Saki’s 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 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.”

The San Diego sun was warm and bright on Wednesday afternoon, but it didn’t stop the crowds from filling the aisles at IPC APEX EXPO 2023 for the trade show’s second official day. Technical conferences, professional development courses, and a keynote from IPC President and CEO John W. Mitchell kept attendees busy. But the real highlight of the day was upstairs where approximately 300 high school students from the local San Diego area rode buses to the San Diego Convention Center for a day full of activities meant especially for them.

STEM Program: Evolving and Growing

01/16/2023 | Charlene Gunter du Plessis, IPC Education Foundation
IPC has a responsibility to its current members but also in attracting and retaining new talent to the electronics manufacturing industry. This is no more evident than in the STEM event hosted by the IPC Education Foundation at IPC APEX EXPO. For the 2023 event, more than 500 students from nearly a dozen high schools are expected to participate in hands-on activities, touring the show floor, and learning from industry experts. The Career Panel Luncheon will expand across the in-person event as we broadcast and stream to schools across the United States.

Five-Star Reflow Recipes: Q&A With Rob Rowland

12/28/2022 | Andy Shaughnessy, I-Connect007
In this Q&A, Rob Rowland, director of engineering at Axiom Electronics, discusses his new IPC APEX EXPO Professional Development course, “Reflow Profiling Simplified,” on how to create a standardized methodology to accurately generate new reflow soldering profiles. Rob explains, “In this class, I’ll explain how I approached this work to help others develop similar methodologies for creating their own reflow soldering profiles. My presentation also includes the basic reflow profile recipes I have been using for the past 20 years.”
