Shengyi Technology Co., Ltd. (SYTECH), founded in 1985, is a global core supplier of electronic circuit base materials which integrates R&D, production, sales, marketing, and technical services. After more than 30 years of development and continuous efforts of every employee, SYTECH produced more than 81 million square meters of laminate materials in 2016. According to the statistics and ranking of global rigid laminators released by Prismark, a US research institution, SYTECH has been the world’s second-largest CCL manufacturer in terms of sales volume, from 2013 to 2017.


SYTECH maintains the highest standards which support products that exhibit exceptional quality, performance, and reliability. SYTECH independently produces high-end electronic materials, including CCL, prepreg, insulation boards, metal-based CCL, resin-coated copper (RCC) and coverlay materials. Products are mainly used for making single and double-sided printed circuit boards as well as multilayer boards. Typical uses for our products would be in products such as in home appliances, portable and consumable electronics, automobiles, computers, aerospace, communication networking as well as other high-end electronic products. 

SYTECH’s leading products are qualified by many world-famous companies, such as Huawei, ZTE, Nokia, Bosch, Lenovo, Sony, Samsung, and Philips, forming a large competitive advantage for SYTECH. Products are exported to many countries and regions including America, Europe, Korea, Japan, and Southeast Asia.
