On June 6th, 2019, the Ministry of Industry and Information Technology officially issued 5G commercial licenses to China Mobile, China Telecom, China Unicom and China Broadcast, marking that China officially entered 5G commercial year.

With the coming of the 5G era, the demand for communication-related PCBs soar and the drilling procedure becomes the new challenge of capacity, adding stacks and efficiency improvement are imperative! Compared to common PCBs, one of the remarkable features of the communication PCBs is thickness, and the technical requirements and process difficulty increase significantly, which asks for higher-aspect ratio and more stable drills.

Jinzhou has focused on high-aspect ratio drills for a long time. At present, Jinzhou is able to provide mature products for communication boards, package boards, and other common boards.
