What this manufacturer makes
Chengzhiyi develops and manufactures conventional and metal-based printed circuit boards. Its company introduction identifies a Shenzhen technical headquarters and production operations in Dongguan and Ji’an. The product portfolio includes aluminum- and copper-based boards, high-frequency boards, multilayer circuits and rigid-flex constructions. The metal-board process sheet is particularly useful for thermal-management projects because it separates substrate thickness, copper weight, machining methods and electrical testing. Those values require confirmation against the specific dielectric system and thermal path in the proposed design.
