Chemical Etching Ultra-thin Vapor Chamber Products Rapid Turnaround

Vapor Chamber Overview

Vapor Chambers are high-performance heat spreaders used for efficient thermal management in advanced electronic devices. At Xinhaisen, we specialize in the precision metal etching of vapor chamber plates and lids. Our process creates intricate internal wick structures and cavity features with exceptional accuracy, enabling superior heat transfer and dissipation. Ideal for high-power applications, our etched vapor chambers ensure reliable thermal performance in compact spaces.

Manufacturing Process

• Material Selection & Cleaning: High-purity copper or other metal sheets are meticulously cleaned.

• Photoresist Lamination: A light-sensitive film is applied to the metal.

• Precision Exposure & Development: Using a digital phototool, the complex wick pattern and chamber outline are exposed and developed onto the metal.

• Controlled Etching: The exposed areas are etched to form precise micro-channels, pillars, and cavity recesses with smooth, burr-free edges.

• Stripping & Inspection: The photoresist is removed, and each component undergoes rigorous quality checks.

• Assembly & Sealing (Client or Partner Integration): The etched plates are typically assembled (welded/bonded), evacuated, and filled with working fluid by our partners or as per client specifications to form the final vapor chamber.

Vapor Chamber Key Features

• Ultra-Fine Wick Structures: Capable of etching complex micro-channel and mesh patterns for optimal capillary action.

• High Flatness & Uniformity: Ensures perfect contact with heat sources (e.g., CPU, GPU) for minimal thermal resistance.

• Custom Cavity Designs: Flexible etching allows for various shapes, sizes, and internal support pillar layouts.

• Burr-Free & Stress-Free: The etching process produces no mechanical stress or debris, critical for vacuum integrity.

• Material Versatility: Available in oxygen-free copper (common), stainless steel, or alloys for specific compatibility.
