MGC Electrotechno Co., Ltd. is a Japanese manufacturing company and a wholly owned subsidiary of Mitsubishi Gas Chemical Company, Inc. (MGC), one of Japan’s leading chemical manufacturers. The company specializes in the production of copper-clad laminates (CCL) and prepregs (PP) based on its parent’s proprietary BT resin technology. These advanced electronic materials form the foundational substrates for semiconductor packages and printed circuit boards, supporting high-speed, high-reliability applications in smartphones, 5G/6G infrastructure, IoT devices, AI data centers, automotive electronics, and other high-performance systems.
Established in 1991 and renamed in 2012, MGC Electrotechno operates its primary manufacturing facility in Nishishirakawa-gun, Fukushima Prefecture, Japan, functioning as the group’s “mother factory” for new product development, advanced high-mix low-volume production, and quality leadership. It maintains ISO 9001 and ISO 14001 certifications and is noted for world-leading positions in ultra-thin laminate materials used in mobile devices. To enhance supply chain resilience, the company fully owns MGC Electrotechno (Thailand) Co., Ltd., established in 2012 as a high-volume production base under a dual-site business continuity plan (BCP) strategy. The Thai facility complements Japanese operations by focusing on standardized, large-scale output while the Fukushima site handles specialized and innovative grades.
As part of the MGC Group’s electronic materials division, MGC Electrotechno plays a critical role in the global semiconductor supply chain, enabling the miniaturization, thermal management, and electrical performance required by next-generation electronics. The company emphasizes environmental considerations, including halogen-free BT materials, and maintains a stable, high-quality supply to major electronics manufacturers worldwide.
