Precision Laser Cutting for 0.01mm (10μm) Magnetic Steel Sheet Processing in precision sensors EMI shielding foils and flexible electronics
Product Description
0.01mm (10μm) Precision Laser Cutting for Magnetic Steel Sheet Processing
Overview:
Ultra-thin magnetic stainless steel sheets with a thickness of 0.01mm (10μm) are widely used in high-tech applications that require extreme precision, magnetic properties, and excellent surface quality. These ultra-thin sheets are commonly processed using high-precision laser cutting, offering burr-free edges, high repeatability, and micro-feature capability for advanced industries.
Applications:
1. Precision Sensors
Magnetic steel foils at 10μm thickness are used in the manufacturing of miniature sensors for automotive, aerospace, medical, and industrial applications.
Their magnetic properties make them ideal for use in magnetic field detection, Hall sensors, and positioning systems.
Laser cutting allows for the precise fabrication of micro-slots, apertures, or complex patterns needed for high-performance sensor functionality.
2. Electromagnetic Interference (EMI) Shielding Foils
Thin magnetic stainless steel foils are excellent materials for EMI/RFI shielding in electronic devices such as smartphones, tablets, communication modules, and industrial control systems.
10μm steel sheets serve as high-frequency shields due to their magnetic permeability and conductive nature.
Laser cutting ensures accurate apertures and shapes to match custom-designed shielding enclosures or printed circuit board (PCB) layouts.
3. Flexible Electronics
In flexible electronics, ultra-thin magnetic foils are used as substrates or support layers for flexible circuits and wearable devices.
The 10μm thickness allows for bending, flexing, and layering, while retaining structural and magnetic properties.
Precision laser cutting supports the creation of micro-scale components with high edge quality and minimal heat-affected zones, crucial for reliable flexible electronics integration.
