Bespoke Etched EMI/RFI Shieldings for 5G Devices From Prototype to High-Volume Production

EMI Shielding Overview
Our EMI (Electromagnetic Interference) shieldings are precision-made metal enclosures or cans designed to protect sensitive electronic components from external electromagnetic radiation and prevent internal signals from interfering with other devices. Manufactured through chemical etching, they offer superior precision and customization for modern electronics.

What is Chemical Etching?
Chemical etching is a precision manufacturing process that uses chemical solutions to selectively remove metal material, creating burr-free, stress-free components with high dimensional accuracy and complex designs without tool wear.

EMI Shielding Features

• Precision Fit: Excellent dimensional accuracy ensures perfect component coverage

• Custom Designs: Complex ventilation patterns, tabs, and features without additional tooling

• Lightweight: Thin materials reduce overall device weight

• No Tooling Marks: Etching produces smooth edges without burrs or stress points

• Fast Prototyping: Quick design changes without expensive hard tooling

• Selective Plating: Solderable surfaces only where needed, reducing costs
