Its roles Owner Operator
MGC Electrotechno (Thailand) Co., Ltd. is a manufacturing subsidiary of MGC Electrotechno Co., Ltd., which is part of the Mitsubishi Gas Chemical Company, Inc. (MGC) group. Established in January 2012 in Rayong Province, Thailand, the company is 100% owned by its Japanese parent and serves as a key production base for BT laminated materials used in semiconductor packaging.
The primary activities involve the production of prepregs and copper clad laminates (CCL) based on BT resin technology. These materials are essential for semiconductor substrates due to their high thermal resistance, superior electrical insulation properties, and resistance to metal ion migration. The facility focuses on high-volume production of standard grades, complementing the advanced and high-mix production at the mother plant in Fukushima, Japan, as part of MGC's business continuity plan (BCP) for global supply chain resilience.
Operating in the WHA Eastern Seaboard Industrial Estate, the company exports its products to major markets including Japan, South Korea, Taiwan, and China. It has expanded its production capacity significantly, with a major plant addition completed in 2025 that approximately doubled output to meet rising demand from AI data centers, 5G/6G communications, and high-performance computing applications. The company employs approximately 354 staff and maintains quality certifications such as ISO 9001 and IATF 16949.
As a specialized electronic materials manufacturer within the MGC group, it plays a vital role in supporting the semiconductor industry's growth by providing reliable, high-quality packaging materials and contributing to diversified supply chains.
Also known as MGC ELECTROTECHNO (THAILAND) CO.,LTD., MGC-ETT, and ETT.
