Precision Laser Cutting for 0.02mm (20μm) Magnetic Steel Sheet Applications in EMI Shielding And Roll-to-Roll Microstructure Fabrication
Product Description
Precision Laser Cutting for 0.02mm (20μm) Magnetic Steel Sheet
Applications in EMI Shielding and Roll-to-Roll Microstructure Fabrication
Overview:
Ultra-thin 0.02mm (20μm) magnetic stainless steel sheets are widely used in advanced electronic applications where high magnetic permeability, dimensional stability, and micro-scale patterning are critical. Precision laser cutting is the ideal processing method for such materials, enabling the creation of highly detailed microstructures with excellent edge quality and minimal thermal distortion.
Key Applications:
1. EMI Shielding (Electromagnetic Interference)
20μm magnetic steel sheets are used as shielding foils in mobile devices, medical equipment, aerospace electronics, and automotive control systems.
These thin foils provide effective high-frequency noise suppression and magnetic shielding, thanks to their excellent permeability and conductivity.
Laser cutting enables custom aperture patterns, shielding grids, and ventilation designs while maintaining precise dimensions.
2. Roll-to-Roll Microstructure Fabrication
In high-throughput manufacturing environments, roll-to-roll (R2R) processing is key to producing flexible components at scale.
0.02mm magnetic steel is suitable for continuous fabrication of micro-perforated sheets, sensor substrates, and filter membranes.
Precision laser systems enable non-contact, burr-free, and high-speed patterning directly on the moving web, ensuring efficiency and repeatability.
Advantages of Precision Laser Cutting at 20μm:
Micron-Level Accuracy: Enables detailed microstructures and tight tolerances.
Non-Thermal Damage: Minimal heat-affected zone (HAZ) preserves material properties.
Roll-to-Roll Compatibility: Continuous web handling and in-line integration.
Custom Geometry: Supports complex designs, such as slots, holes, and mesh patterns.
No Tool Wear: Laser cutting ensures long-term consistency without mechanical degradation.
