Anti metal magnetic sheet | Key materials in the field of electromagnetic compatibility and innovative practices of advanced institute technology

In today's highly integrated electronic devices, the interference of metal environments on wireless signals is becoming increasingly prominent. As the core material to solve this problem, metal resistant magnetic plates play an irreplaceable role in RFID tags, NFC payments, wireless charging and other scenarios through their unique magnetic permeability characteristics and electromagnetic shielding capabilities. Advanced Institute (Shenzhen) Technology Co., Ltd. (hereinafter referred to as "Advanced Institute Technology"), as a new material technology solution provider, has provided important support for the technological breakthrough and industrial application of anti metal magnetic sheets through its deep cultivation in the fields of shielding materials and absorbing materials.

The core value and technical principle of anti metal magnetic plates

Anti metal RFID magnetic layerIt is mainly made of soft magnetic materials such as ferrite and nanocrystalline alloys, and its core function is to suppress the reflection of electromagnetic waves and eddy current effects on the metal surface, while guiding the concentrated distribution of magnetic fields and improving the stability of electronic devices in metal environments. In RFID and NFC applications, metal objects are prone to signal attenuation or reading failure, while magnetic plates, with their high magnetic permeability (such as NiZn ferrite with a permeability of over 150), can bind electromagnetic beams between tags and card readers, significantly enhancing communication distance and reliability. In addition, magnetic plates can absorb electromagnetic noise and reduce mutual interference between electronic devices, making them one of the key materials for achieving electromagnetic compatibility (EMC).

From a technical perspective, high-quality magnetic sheets need to meet three major requirements simultaneously: high magnetic permeability, low magnetic loss, and thinning. For example, the thickness of the Research Platinum brand magnetic sheet launched by Advanced Institute Technology can be controlled at 0.10 ± 0.03mm, with stable magnetic permeability and magnetic loss of less than 5% in the high frequency range of 13.56MHz, perfectly adapting to the design requirements of lightweight devices such as smartphones and smart wearables.

This series of products has passed RoHS environmental certification, meeting the stringent requirements of consumer electronics, medical equipment and other fields.

2. Research platinum brand anti metal interference magnetic sheet

Developed for scenarios such as RFID anti metal tags and NFC phone magnetic isolation, using NiZn ferrite as the substrate, and optimizing the formula and sintering process to achieve gradient adjustment of magnetic permeability between 150-300. For example, the magnetic plate of model XJY-1009 can not only adapt to the 13.56MHz frequency band, but also customize its size to meet the requirements of irregular devices. Currently, it has been widely used in fields such as smart door locks and logistics traceability labels.
