Commercialized the industry's top class high-speed inspection^*1
"CT type X-ray automatic inspection system” High production quality for advanced semiconductors and electronic components, which are in increasing demand due to the spread of generative AI and xEVs.

• Shimogyo-ku, Kyoto, Japan – November 21^st 2023

OMRON Corporation (Headquarters: Kyoto, Japan; President and CEO: Junta Tsujinaga) OMRON has developed three models of CT type automatic X-ray inspection systems*² that enable industry-leading high-speed 3D inspection: the VT-X750-XL, VT-X850 and VT-X950 (Referred to as the X750, X850, and X950 respectively. They will be released sequentially from February 2024 onward. Prior to the launch, OMRON will introduce the X950 and its inspection examples at the OMRON booth at SEMICON Japan 2023 to be held at Tokyo Big Sight from December 13th to 15th, 2023.

VT-X950 CT type automatic X-ray inspection system

Recently, the amount of information used in the world is rapidly increasing with the expansion of user access to generative AI and data centers for interactive artificial intelligence and the development of 5G/6G communications, and the further miniaturization of semiconductors used for these applications is progressing.
In particular, miniaturization technology has advanced to a high level of technological difficulty, and along with miniaturization, the need for packaging using integration technology called chiplets will increase in the future. Unlike conventional flat designs, chiplets require more precise inspections as their structures become more complex through three-dimensional mounting.
The automotive industry, in particular, is becoming more environmentally friendly with the development of xEVs, and integrated EV modules (X in 1) that combine multiple functions, such as eAxle. Efforts are underway for 3D packaging to realize further space saving and higher efficiency in module design. Products using 3D packaging, which are being introduced in a variety of industries, are difficult to determine if they are good using conventional 2D-X-ray inspection systems with transmission images, making it a major challenge to achieve both productivity and quality. At the same time, there is a growing need for stable production at multiple sites in preparation for the duplication of supply chains, and the establishment of a production system that is not overly dependent on human interaction.

In response to these needs, three newly commercialized models of automatic CT-type X-ray inspection systems combine OMRON's proprietary control and image processing technologies to achieve high-speed, high-precision inspection. The combination of continuous imaging technology*5 and a high-sensitivity camera through seamless control of the equipment achieves high-speed imaging of high-resolution, easy-to-distinguish 3D images.
In addition, high-speed generation of modeling using state-of-the-art 3D inspection technology, which is also used in medical CT scanners, enables in-line quality inspection, which has been difficult to achieve at manufacturing sites. Utilizing proprietary AI technology, the system automatically optimizes the setting of inspection imaging conditions and automates the creation of inspection programs that were previously difficult only for skilled engineers and technicians.

OMRON has been contributing to the improvement of productivity at manufacturing sites by leveraging its strength in control technology under the Innovation Concept innovative-Automation. We will continue our efforts to improve productivity and to evolve into a sustainable at manufacturing site. OMRON will enrich the future for people, industries and the globe by innovative automation.
