What this manufacturer makes
Lianchuang Circuits specializes in prototype and small-to-medium-batch printed circuit boards. Its official introduction describes high-mix, short-cycle work for communications, industrial control, medical devices, power electronics, automotive systems and computing. The product catalogue includes Rogers-based boards, mixed-laminate constructions and metal-based designs. Rather than combining its entire process table into a single promise, this product profile records a specific two-sided copper-based catalogue example and keeps its dimensions separate from other board types.
