What this manufacturer makes
Mutualtek manufactures rigid-flex, rigid PCB and substrate products in Changshu, Jiangsu. Its official technical information separates these product families and provides both capability tables and a dated process outlook. The rigid-PCB table identifies a 2–18-layer range with different inner- and outer-layer routing limits. The company also describes production tracking and traceability processes. Those disclosures explain its manufacturing approach, but they do not establish the batch history of a particular order or prove that every board family uses the same line.
