【TAIYO Web Shop News】 The TAIYO Web Shop is currently selling the 'Super Water-Repellent Film' with great acclaim! We provide a clear view with its amazing 'water-repelling power.' To access our e-commerce site, please scan the QR code on the right side of the page or visit the following URL: https://taiyo-xelcom.easy-myshop.jp/ We offer a lineup of roll, pre-cut, and rotating window options! *Please note that the application is limited to 'marine use,' but feel free to contact us if you are interested. By applying a special processing to the film's surface inspired by lotus leaves, we have recreated the lotus effect. We have received feedback from marine operators and those in the fishing industry, such as: - The film repels splashes of water, improving visibility. - Sea salt would dry and stick, making cleaning a hassle, but the workload has significantly decreased. - The anti-reflective feature has made it easier to see handheld measuring devices. - Applying it to both the front and back of windows (glass) has resulted in clear visibility even at night.

Thank you very much for your many visits during the event. You can find information about the exhibited machines on the product pages. ■ Final Appearance Inspection Device [NEW] TY-VISION M111SC ■ Electrical Inspection System TY-CHECKER DS401 "Flexible inspection solutions for various applications!" Booth Number: 2B-12 Exhibition: JPCA Show 2023 Exhibition Zone: Printed Circuit Board Technology Exhibition We are showcasing two types of inspection devices: an appearance inspection machine and an electrical inspection machine. Both inspection machines are designed utilizing the know-how accumulated as an FPC manufacturer, allowing us to propose the optimal inspection methods for electronic circuit boards. The appearance inspection machine is the latest model M111SC, equipped with our smallest resolution camera at 2.5µm. The electrical inspection machine is the latest model DS401, featuring even higher performance functions from the DS series, which is specialized for FPC. Please stop by and take a look at each inspection machine at the venue.

We are advancing the development of high-performance for our appearance inspection system, the "TY-VISION series," and we are pleased to announce the completion of the appearance inspection device "TY-VISION M111SC," which is equipped with an optical system featuring an optical resolution of 2.5μm. In recent years, driven by the further expansion of DX and IoT, the spread of 5G communication networks, and the advancement of digitalization in society, as well as the transformation of the automotive industry with the progress of autonomous driving and electrification, the semiconductor market continues to thrive. The quality levels of various substrates are rising, particularly for high-definition substrates, and we have developed the "TY-VISION M111SC" to meet market demands. Please refer to the attached file for more details.

The A300 series, suitable for package and module circuit boards, now finally includes a 3µm specification model! We have started accepting orders for the optical resolution 3μ, fully automatic final appearance inspection system for circuit boards, 'TY-VISION A308DC.' It is ideal for the final appearance inspection process in a clean room!

In recent years, we would like to introduce the content of our press releases as materials for everyone to see. Genre: Final Appearance Inspection Equipment for Circuit Boards

We are pleased to announce that we have developed sales channels for flexible printed circuit boards (FPC) in the U.S. medical device market within our core business of electronic substrates. Traditionally, FPC has been primarily used in smartphones, digital cameras, and automotive equipment; however, in recent years, we have focused on product development for medical devices, which is one of the growing markets due to changes in the market environment. As a result, the proportion of FPC sales to medical device manufacturers within our group reached 12.9% in fiscal year 2021 and 15.7% as of the third quarter of fiscal year 2022, with a trend of increasing orders. Further details will follow (please see the attached file). This is our press release, and we would like to inform you that it has been featured in the "Printed Circuit Journal," the only specialized magazine in the printed circuit board industry. (We have received approval for the publication in the magazine.)

Our company sells mirror polishing machines manufactured by our consolidated subsidiary, Mirac Co., Ltd. These machines have primarily been used for the final mirror polishing of gravure printing rolls and for surface polishing of hydraulic cylinders in industrial equipment. As a result of our marketing activities in this business, we are pleased to announce that we have achieved results in polishing the surfaces of plating rolls used in the production of lithium-ion batteries, which are experiencing growing demand. In recent years, lithium-ion batteries have rapidly expanded not only in mobile devices but also as a power source for passenger cars and other applications. We recognize this as a business opportunity and will further advance the market development of mirror polishing machines.

This is an introduction to the UTRON-made cable tester from Taiwan. Our company handles the 'UT8080A', which does not overlap with our in-house power inspection equipment. It is functionally simple, but can select up to 512 points (128, 256, 384, 512), making it suitable for testing with fewer points. For more details, please visit the product page or catalog page. Inquiries are very welcome. Contact: Hashimoto (073-431-6327)
