at its Assembly and Test Facility in Chengdu, China

Plano, Texas – July 24, 2015 -- Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today held the production commencement ceremony for Diodes Technology (Chengdu) Company Limited’s assembly and test facility at Chengdu Hi–Tech Industrial Development Zone (CDHT).

Established in December 2010 as a joint venture between Diodes Incorporated and Chengdu Ya Guang Electronic Company Limited (5% ownership), Diodes Technology (Chengdu) Company Limited provides semiconductor assembly and testing and is an expansion of the Company’s manufacturing presence in China.  

Dr. Keh-Shew Lu, President and Chief Executive Officer of Diodes Incorporated, led the ceremony. Also in attendance were provincial, city and CDHT officials, media guests, business partners, as well as members of the Company’s senior management.

Commenting at the ceremony, Dr. Lu stated, “The Chengdu facility will become Diodes largest production center in China and will play a key role in supporting our long-term growth. When fully equipped, the facility will have three times the available capacity as our Shanghai assembly and test site, which was 32 billion units last year. Today’s achievement of mass production represents an important milestone since launching the pilot line in the second quarter of 2011. We expect to reach an estimated monthly run rate of 400 million units by the end of this year, and run rate of 1.2 billion units by the end of next year. With the addition of the Chengdu facility to our existing packaging capabilities, we are now well positioned with the capacity to meet customers’ growing future demand.”
