Overseas Subsidiary Established for the Production of Electronic Materials
Mitsubishi Gas Chemical Company, Inc. (MGC; Head Office: Chiyoda-ku, Tokyo; President:Kazuo Sakai) has established a subsidiary for the production of electronic materials in theKingdom of Thailand. The construction of the production plant for copper clad laminates andprepregs will begin in May 2012 and is scheduled for completion in April 2013. Following
prototyping and sample evaluation, the new plant will start commercial operation toward the end of2013.
As core products of MGC’s electronic materials business, BT materials have long found use insemiconductor package substrates, helping MGC achieve the highest share of the market. BTmaterials have been produced exclusively at the group’s plant in Nishishirakawa-gun, Fukushima
Pref., which is operated by the MGC subsidiary Electrotechno Co., Ltd. (ET; Head Office:Chiyoda-ku, Tokyo; President: Takayuki Watanabe).
In recent years, however, MGC has considered the establishment of another overseas
production in line with the reality that 80% of the group’s BT products were exported.
Furthermore, MGC received requests from customers all over the world for it to establish asecond production site after the temporary suspension of BT material production due to the Great
East Japan Earthquake in March 2011. Thus, MGC decided to establish the new production
subsidiary also from the perspective of business continuity plans (BCP).
MGC studied many possible locations in and outside Japan from a holistic perspective before
selecting the final location in Thailand.
In the short and medium term, this project represents part of the BCP. We will ensure a morestable supply of our products through the introduction of a production line in Thailand capable ofproducing any kind of BT material and high-performance FR-4 materials currently produced by ET.
In the medium to long term, the project will build a global structure for the supply of electronicmaterials with two sites in Japan and Thailand, preparing for market expansion from East toSoutheastern Asia in the future.
