Precision Laser Cutting for 0.03mm (30μm) Magnetic Steel Sheet Applications in Smartphone Components And Micro Housing Structures
Product Description
Precision Laser Cutting for 0.03mm (30μm) Magnetic Steel Sheet
Applications in Smartphone Components and Micro Housing Structures
Precision laser cutting of 0.03mm (30μm) magnetic steel sheets is essential for manufacturing high-performance micro-components in the electronics industry. These ultra-thin magnetic materials are widely used for producing micro housings, shielding layers, structural frames, and precision inserts in smartphones, wearables, and miniaturized devices.
Laser technology enables non-contact, high-accuracy machining without mechanical deformation, making it ideal for delicate components with tight tolerances.
Key Applications:
1. Smartphone Components
Used in internal shielding, antenna isolation, and micro-frame support.
Laser-cut magnetic steel provides precise geometry and stable magnetic performance to enhance signal clarity and EMC (electromagnetic compatibility).
Ideal for thin battery compartments, speaker mesh frames, and NFC module support frames.
⚙️ 2. Micro-Component Housings
30μm magnetic sheets are ideal for micro-enclosures, such as in sensors, MEMS devices, or micro-actuators.
Offers mechanical strength and EMI protection in ultra-compact spaces.
Laser cutting supports custom contours, fine slits, and venting holes without mechanical stress or burrs.
Advantages of Laser Cutting for 30μm Sheets:
Micron-level precision for high-density component integration.
No tool wear – consistent quality across long production runs.
Non-contact processing – no deformation of ultra-thin substrates.
Clean edges and low burr – minimal post-processing needed.
Supports complex geometries – ideal for intricate part designs.
