Notice of Company Name Change In order to strengthen our brand power and aim for further business expansion and enhancement of corporate value in the future, we have changed our company name from "Taiyo Kogyo Co., Ltd." to "Taiyo TechnoRex Co., Ltd." Additionally, we have refreshed our corporate logo to align with the name change. [Thoughts Behind the New Company Name] The coined term "TECHNOLEX," derived from "Technology" and "Flexible," symbolizes the flexibility of our main product, FPC (Flexible Printed Circuit Board), as well as our commitment to adapt flexibly to new technologies and areas such as technology trading, beyond conventional techniques. We are evolving to break out of the confines of "industry" and to transition towards a more global market. For more details, please check here.

We will explain the development concept and features of the latest automatic machine 'TY-VISION A308DC', which was exhibited at Nepcon Japan 2023, as well as future plans. We have released a final appearance inspection device for high-precision substrates, suitable for package and module substrates. An online exhibition hosted by evort: 'Semiconductor and Electronic Components Comprehensive Exhibition' [Semiconductor Inspection, Measurement, and Analysis Exhibition] has added a new webinar. You can view explanations of the latest image inspection technology and future prospects.

【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.

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.

Our company is working on the development of build-up substrates using polyimide for the insulating layer, aimed at miniaturizing, thinning, and lightening multilayer substrates in our core electronic substrate business. We are pleased to announce that we have established the core filled via technology. In electronic devices that are becoming lighter, more compact, and high-functioning, substrates (build-up substrates) capable of high-density wiring and high-density mounting are in demand. However, typically, the core layer of build-up substrates uses rigid boards, which increases the thickness of the substrate and hinders the lightweight and compact design of electronic devices. The filled via technology we have established involves filling holes (vias) made by laser in flexible printed circuit boards (FPC) with an insulating layer of polyimide with copper, and flattening the surface of the filled areas. By using this FPC as the core layer or outer layer of build-up substrates, it becomes possible to achieve both high-density wiring and high-density mounting along with thinning. We plan to start providing build-up substrates using this technology within the fiscal year 2022, and furthermore, by applying this technology to our strength in high-frequency compatible FPCs, we will respond to the demand for miniaturization of communication devices.
