China PCB manufacturer have begun delivering IC substrates, high-end multilayer PCB boards and HDI PCB boards for notebook, networking device and consumer electronics applications, which will gradually affect sales of Taiwan-based PCB manufacturer and IC substrate suppliers, according to industry watchers. Buoyed by the rise of China-based brands, including Lenovo, ZTE, Huawei and TCL, China has built up a PCB ecosystem containing upstream material suppliers for copper foils, CCL and FCCL, and also PCB suppliers for traditional circuit board, multilayer PCBs, and HDI PCB boards, noted the watchers.
