How to improve the electromagnetic interference resistance of high permeability and low loss magnetic separators?

1. Introduction

High permeability and low loss magnetic isolation sheetWidely used in various electronic devices, such as mobile communication base stations, smartphones, tablets, electric vehicles, etc., it is used to protect sensitive circuits from external magnetic fields and prevent electromagnetic waves generated internally from leaking out and affecting other devices. It is crucial to improve the electromagnetic interference resistance of these magnetic separators in order to meet the growing demand for applications.

2. Key factors for improving the ability to resist electromagnetic interference

2.1 Material selection and modification

• High saturation magnetic induction intensity: Choosing materials with high saturation magnetic induction intensity (Bs) can more effectively guide and concentrate magnetic field lines, thereby enhancing the shielding effect.
• Low coercivity: The smaller the coercivity (Hc), the easier it is for the material to be magnetized or demagnetized, which helps to quickly respond to changing magnetic field environments.
• High frequency loss characteristics: Reducing the eddy current loss and hysteresis loss of materials at high frequencies is one of the important ways to enhance their anti-interference ability.

2.2 Structural Design

• Multilayer composite structure: The combination of multiple layers of different materials can not only increase the total magnetic permeability, but also form an effective impedance matching interface, further weakening the penetration ability of electromagnetic waves.
• Micro nano structure regulation: Introducing nanoparticles or special arrangements can change the propagation path of electromagnetic waves, achieving better reflection and absorption effects.

2.3 Manufacturing Process Optimization

• Precision molding technology: ensures the shape accuracy and flatness of the magnetic separator, avoiding local magnetic field leakage caused by deformation.
• Uniform coating treatment: Coating a thin and uniform layer of metal or other functional coating on the surface can improve the surface condition of the material, enhance its corrosion resistance and mechanical strength.
