The first Teradyne test system in China, a T317, was shipped in 1979 to the Guangzhou Eastern Factory for semiconductor device manufacturing. Since that time, Teradyne has grown with China's technology industry. Currently, more than 200 Teradyne semiconductor systems and more than 600 circuit board test and inspection systems are installed in the country. Teradyne also provides Connections Systems' products and services to a growing list of Chinese communication companies and in addition, provides manufacturing and test services for the Integra J750 line of semiconductor test systems in the Shanghai facility.
