Precision Etching Stainless Steel EMI Shielding OEM/ODM Customized 

EMI Shielding Overview

Xinhaisen Technology specializes in manufacturing high-performance EMI/RFI shielding components through precision chemical etching. Our shielding solutions provide superior electromagnetic interference protection for electronics in telecommunications, medical devices, aerospace, and automotive applications, ensuring compliance with international EMC standards.

EMI Shielding Features

• High Shielding Effectiveness: Precise control over aperture size and pattern ensures optimal attenuation across target frequency ranges.

• Design Complexity Made Simple: Easily integrate spring fingers (beryllium copper/nickel silver), ventilation grids, mounting tabs, and irregular shapes without additional assembly.

• Burr-Free & Consistent: Etching eliminates the micro-cracks and burrs common in stamping, which can compromise shielding and cause short circuits.

• Lightweight & Low-Profile: Ideal for modern, compact electronics where space and weight are at a premium.

• Excellent Material Options: Available in various shielding alloys, including cold-rolled steel (CRS), stainless steel, copper, and beryllium copper for optimal conductivity and resilience.

• Rapid Prototyping: Test and iterate shield designs quickly with minimal cost and lead time.

EMI Shielding Applications

• Consumer Electronics: Shielding cans for smartphones, tablets, wearables, routers, and audio equipment.

• Telecommunications: RF modules, base station components, antenna shields.

• Medical Devices: Shielding for sensitive monitoring, imaging, and diagnostic electronics.

• Automotive Electronics: Control units (ECUs), infotainment systems, ADAS sensors.

• Industrial & IoT: PLCs, sensors, gateways, and any device requiring EMC compliance.

FAQ

Q: Why choose etched shields over stamped ones?
A: Etching offers greater design freedom (complex shapes, finer vents), faster prototyping, no tooling cost, and superior part consistency without burrs or stress that can affect fit and performance.

Q: How do I ensure my shield design is effective?
A: We can work with your EMC requirements. Key factors are material choice, seam design (including finger spacing and contact), and aperture size/shape for necessary ventilation. We provide DFM feedback to optimize your design for manufacturing and performance.

Q: Can you supply formed (3D) shielding cans?
A: Yes. We provide precision etching of the flat blank, followed by accurate forming and soldering (if required) to create complete five-sided or more complex enclosures.

Q: What about plating for corrosion resistance and solderability?
A: We offer various platings. Tin plating is standard for solderability and cost-effectiveness. Nickel plating offers better corrosion resistance for harsh environments.

Q: What is the lead time for prototype shields?
A: We can typically deliver first-article prototypes within 5-10 working days after design approval, allowing for rapid testing and iteration cycles.
