Qualtec Co.,Ltd.

As described in this report, our business is organized around 3 core areas—analysis, reliability evaluation, and precision processing—and is operated as a business group that includes affiliated companies. The reliability evaluation business primarily conducts environmental, electrical, and power-cycling tests on electronic components and other products, as well as failure analysis, sample preparation, analysis, and the design, manufacture, and sale of testing equipment. We have established an integrated structure that also covers analysis and improvement proposals for upstream and downstream processes. The precision processing business provides surface-treatment technologies, including prototyping and volume-production laser processing for build-up substrates and flexible printed circuit boards, development of surface-treatment conditions, and prototyping. In other businesses, we provide testing and quality consulting services in biotechnology-related fields. As a next-generation growth business, we are advancing the Universal Plating Method (MAP) project, seeking to commercialize metal deposition on glass, resin, ceramics, and other materials while establishing technologies with a low environmental impact. As part of our business structure, we are developing R&D centers, including facilities for the MAP project, establishing industry-academia collaboration frameworks, demonstrating technologies for glass-core substrates, and disseminating results through academic presentations and other channels. We also own ＳＧＳクオルテック株式会社 as an affiliated company and are advancing businesses including the reliability evaluation business.
