Chemical Metal Etching EMI Shieldings for the US Electronics Industry

EMI Shiedings Overview
Xinhaisen Technology specializes in the manufacturing of high-precision metal EMI (Electromagnetic Interference) shielding parts through advanced chemical etching processes. Our shields are designed to effectively block or contain electromagnetic radiation, ensuring the optimal performance and regulatory compliance of sensitive electronic devices across various industries.

Manufacturing Process
Our EMI shielding parts are produced using state-of-the-art photochemical etching. This subtractive manufacturing process involves:

• Cleaning: The metal sheet is thoroughly cleaned.

• Lamination: Application of a photoresist film.

• Exposure: UV exposure through a precision phototool defining the shield pattern.

• Development: Removing unexposed resist to reveal the etching pattern.

• Etching: Precise chemical etching to form the final shield geometry.

• Stripping & Finishing: Removal of remaining resist and application of final finishes (e.g., plating, passivation).

EMI Shiedings Features

• High Precision & Complexity: Achieves intricate geometries, fine vents, and small apertures without stress or burrs.

• Material Versatility: Compatible with various shielding alloys (e.g., stainless steel, copper, beryllium copper, nickel silver).

• Lightweight & Thin-Walled: Ideal for modern miniaturized electronics without adding significant weight.

• Tooling Flexibility: Low-cost and fast phototool changes enable rapid prototyping and design iterations.

• Excellent Consistency: Uniform etching ensures reliable shielding performance across high-volume production runs.

FAQ
Q: What are the main benefits of etched EMI shields over stamped ones?
A: Etched shields are burr-free, stress-free, allow for more complex and finer designs, and have much lower tooling costs and faster prototyping times.

Q: Can you handle beryllium copper for spring-finger shielding?
A: Yes, we have extensive experience etching beryllium copper and other alloys to create effective conductive gaskets and spring contacts.

Q: What information do you need for a quote?
A: Please provide drawings (DXF, DWG, Gerber), material type/specification, thickness, required plating/finish, and annual usage estimate.

Q: What is your minimum order quantity (MOQ)?
A: We are flexible. We support low-MOQ prototyping and ramp seamlessly to high-volume production.

Q: How do you ensure shielding effectiveness?
A: Our process ensures precise aperture sizes and patterns critical for attenuation. We can also advise on design and material selection to meet target shielding requirements.
