Ultra-Thin Vapor Chambers Copper Metal Etching with High Precision

Vapor Chamber Overview
Xinhaisen Technology specializes in manufacturing high-precision, high-performance vapor chambers (VC) through advanced photochemical etching technology. Vapor chambers are critical components in modern thermal management systems, leveraging phase-change principles (evaporation-condensation) for efficient heat dissipation. We provide tailored solutions for 5G communications, smartphones, AI servers, graphics cards, and other high-end applications.
