Product Description
Product Description
Micro etched copper sheet designed for fine pattern applications requiring ultra-high precision and detail. With advanced etching capabilities, this copper sheet can achieve micro-level features, uniform hole distribution, and excellent consistency. It is ideal for high-end precision components and applications requiring tight tolerances.
Application Field
Widely used in micro components, precision electronics, optical parts, and fine pattern structures. This micro etched copper sheet is suitable for industries demanding high accuracy and fine detail.
Micro Etched Copper Sheet for Fine Pattern Applications
Pushing the boundaries of precision, our micro etched copper sheet is designed for fine pattern applications requiring ultra-high accuracy. We achieve micro-level features and uniform hole distribution with exceptional consistency. In industries where a micron can make the difference between success and failure, standard manufacturing methods simply cannot compete with the capabilities of advanced chemical etching.
Our factory specializes in Micro Precision Metal Processing, delivering components that meet the most stringent tolerance requirements. By leveraging state-of-the-art etching technology, we produce fine pattern structures that are free from mechanical stress, burrs, and heat damage, ensuring the highest level of performance for your most critical applications.
The Standard of Ultra-High Precision
When dealing with micro-components, the margin for error is non-existent. Our micro etched copper sheet products are manufactured in controlled environments to ensure that every feature, no matter how small, is replicated with absolute fidelity.
Key Advantages of Micro Etching
- Micro-Level Features: We can produce apertures, slots, and conductive traces with extreme precision. Our advanced lines are capable of achieving a minimum aperture of 0.1mm, allowing for intricate designs that laser cutting or stamping cannot achieve.
- Tight Tolerances: We maintain strict dimensional control, typically holding tolerances within ±0.01mm. This level of accuracy is essential for components that must fit into complex micro-assemblies.
- Uniform Hole Distribution: Whether you need a fine mesh for filtration or a precise grid for optical alignment, our process ensures that hole distribution is perfectly uniform across the entire sheet, guaranteeing consistent flow or signal transmission.
- Excellent Consistency: Unlike mechanical methods where tool wear can affect quality over time, chemical etching is a non-contact process. This ensures that the first part and the ten-thousandth part are identical in quality and dimension.
Applications for Fine Pattern Components
Our micro etched copper sheet solutions are critical in sectors that demand high accuracy and fine detail.
- Precision Optics: Used for optical apertures, slits, and encoder discs where light transmission and exact geometry are paramount.
- Micro Electronics: Essential for fine-pitch lead frames, micro-shielding, and conductive layers in compact electronic devices.
- Filtration & Separation: High-precision filter meshes and screens for medical or industrial use, requiring uniform pore sizes for accurate particle separation.
- Sensors & Instrumentation: Micro-components for sensitive sensors that require delicate structures to detect changes in pressure, flow, or temperature.
Technical Specifications and Standards
To demonstrate our capability in handling high-end precision projects, we have outlined our standard tolerances and capabilities below.
Parameter | Standard Specification | High-Precision Capability |
|---|---|---|
Minimum Aperture | 0.2mm | 0.1mm |
Tolerance | ±0.05mm | ±0.01mm |
Material Thickness | 0.1mm – 2.0mm | 0.03mm – 0.5mm (Micro) |
Edge Quality | Smooth | Burr-Free / No Recast Layer |
Surface Finish | Standard | High-Definition / Mirror |
Why Choose Chemical Etching for Micro Parts?
For fine pattern applications, the choice of manufacturing process is critical.
Etching vs. Laser Cutting
While laser cutting is a precise thermal process, it has limitations when applied to micro-scale features on thin copper.
- Heat Affected Zone (HAZ): Lasers generate heat that can warp thin copper sheets or alter the material properties at the edge. Our chemical etching is a cold process, preserving the material's integrity.
- Minimum Feature Size: Lasers have a kerf width (cut width) that limits how small a hole can be. Chemical etching can produce significantly smaller and more complex features, such as the 0.1mm apertures we specialize in.
Etching vs. Stamping
Stamping is generally unsuitable for micro-precision parts due to the physical forces involved.
- Tooling Limitations: Creating hard dies for micro-holes is incredibly expensive and the dies wear out quickly.
- Material Deformation: The pressure from stamping can deform thin materials, leading to inconsistent hole shapes. Chemical etching dissolves the metal selectively, ensuring perfect circularity and edge definition.
Quality Control in Micro Processing
We understand that visual inspection is not enough for micro precision metal processing. Our quality control process includes:
- Digital Microscopy: We use high-magnification optical equipment to verify aperture sizes and edge quality.
- Coordinate Measuring Machine (CMM): For critical dimensions, we utilize CMM to ensure the micro etched copper sheet meets the exact CAD specifications.
- Surface Analysis: We check for surface defects, ensuring the fine patterns are free from oxidation or residue.
