NFC/RFID 資訊是通過電磁感應耦合方式傳遞,工作時電磁場到達電池的金屬表面形成的渦流效應,極大地影響 NFC 天線的讀取特性。在天線與電池金屬面之間貼上一片納米晶隔磁片則該問題迎刃而解。
NFC/RFID 系列納米晶隔磁片以鐵基納米晶帶材為主要原材料製成,具有良好的磁性能,高磁導率,低損耗,高飽和磁感,以及良好的頻率特性,可製成最薄至 30μm 的磁性薄片,材料為柔性,不會變形或碎裂。
NFC/RFID information is transmitted through electromagnetic induction coupling method, The eddy current effect is formed in the metal surface by the electromagnetic field at the time of operation, it affects the reading performance of NFC antennas profoundly. It can solve the problem when a piece of Nano-crystalline Magnetic Sheet is placed between the antenna and the battery.
Nano-crystalline Magnetic Sheet for NFC/RFID is made of iron-based Nano-crystalline ribbons, It has good magnetic properties, high permeability, low loss, high saturation magnetic induction, and good frequency characteristics, Min.30μm magnetic sheet can be made, the material is flexible, will not be deformed or fractured.
