Product Specification

Copper Etching Ultra Thin High Precision Brass Vapor Chamber for Cooling System

The etched copper VC heat spreader is a new-generation heat dissipation component manufactured using a precision etching process. Its key feature is the integration of capillary microstructures into the inner wall of the copper housing through chemical etching, thereby achieving thinner dimensions and more efficient heat dissipation.

Features of Etched Ultra Thin Vapor Chamber:

The etching process is a critical technical step in the manufacture of VC heat spreaders. It involves selectively etching a copper substrate through chemical or physical means to form a predetermined microstructure (such as capillary channels, cavities, and support pillars) on the substrate’s surface. Compared to traditional capillary core structures made by laying copper mesh or sintering copper powder, the etching process offers significant advantages:

• High precision and excellent consistency:

Etching precision can reach ±0.01 mm, allowing for precise control of the depth and width of the flow channels and ensuring that the capillary structure is uniform across the entire board surface. This avoids the heat-affected zones and depth inconsistencies that can result from laser processing, leading to more stable heat dissipation efficiency.

• Stress-free and high flatness:

As a non-contact process, etching does not impose mechanical stress on thin copper sheets, effectively maintaining material flatness (controllable within 0.02 mm) and preventing warping and deformation.

• Flexible design and controllable costs:

For complex geometries or internal flow channels, etching requires only modifications to the design files—no additional tooling is needed. This results in lower costs and eliminates defects such as burrs and indentations.

Application of Ultra Thin Vapor Chamber:

• Consumer Electronics: Smartphones, tablets, and ultra-thin laptops
• Advanced Semiconductors: High-performance ICs and 5G communication modules
• Display Technologies: Mini-LED and MicroLED backlight units
• Precision Equipment: Compact aerospace and medical devices

What's Chemical Etching?

Chemical etching, alternatively referred to as photo etching or photochemical machining (PCM), is a subtractive manufacturing process. It achieves high precision and cost-effectiveness in producing complex metal components without introducing mechanical stresses or heat-affected zones.
