What this manufacturer makes
Gongming Circuit manufactures prototype and small-to-medium-batch multilayer PCBs in Hubei. Its official site describes a full manufacturing process, including plating, hole metallization, immersion gold and automated inspection. The company profile dates the operation to 2014. The service information explicitly discusses four-, six- and eight-layer quick-turn work. This listing records that service scope without converting the website’s fastest response statements into a guaranteed delivery time or treating general IPC wording as a qualification for every order.
