Our History
HongTai Technology Co., Ltd, a China-Hong Kong joint venture enterprise, is established at 1997 to focus on electronic PCB and assembly service. At the background of consumer electronics developing rapidly and China’s Reform and Open policy, Shenzhen City has great advantages in electronics manufacturing, including lower labor cost, government’s tax reduced policy, lower land cost, etc. At the beginning, HongTai offer PCB and PCBA OEM service, then we enlarged our products line, and we start to develop FPC and membrane switch.
Our Factory
HongTai specializes in PCB, flex PCB and PCB assembly. They are widely used in computers, industrial controls, digital consumer electronics, medical devices, IT communication, aerospace and other fields.
One-stop services includes PCB layout,PCB fabrication, components sourcing, PCB assembly and finished product assembly.
Advanced test equipment are imported from American, Japan and Germany. HongTai has passed ISO9001, ISO14001 certificate, while products get UL authentication.
