What this manufacturer makes
Huihe Circuit manufactures printed circuit boards in Xinfeng, Jiangxi. Its official introduction lists multilayer boards and specialist constructions including high-frequency, high-speed, heavy-copper, blind/buried-via and mixed-dielectric boards. Its application range includes robotics, communications, computing, industrial control, power and medical equipment. The company’s process table separates volume production from samples. This profile follows the volume column, which is narrower than the headline multilayer range elsewhere on the website, so a buyer can distinguish regular production from sample capability.
