Our own factory, from chip packaging to final test
Shenzhen Goodwork Electronics was founded in 2004 and is recognized in China as a national high-tech enterprise. In 2019 it opened its production base, Jiangsu Goodwork Microelectronics, in Yancheng: a 20,000 m² plant with more than 20 packaging and test lines and over 30 fully automated production lines.
GK Semiconductor North America brings that capacity to Canadian and US manufacturers, with sales, samples and documentation handled from the Greater Toronto Area.
- Own production base in Yancheng, Jiangsu, with in-house test lab
- 5,000 m² of automated warehousing in Shenzhen and Jiangsu
- Listed as a supplier on DigiKey
