1、 Introduction to ferrite sheet:

Using the metal with high magnetic conductivity and high loss, it crystallizes into a variety of soft magnetic alloys in the ultramicro molecule, and layers of strip-shaped films are stacked. The microwave noise generated by the electronic components, modules and surface current can be absorbed efficiently in a wide frequency band, so as to improve the efficiency and reduce the temperature, so as to provide an excellent EMC solution for various electronic equipment.

2、 It has three main functions on wireless charging coil:
1. Magnetic conduction
As we all know, the principle of Qi wireless charging standard is electromagnetic induction. When the primary coil (wireless charging transmitter) works, it will produce an interactive magnetic field (the strength direction changes constantly). In order to make the magnetic field energy emitted by the primary coil act on the secondary coil (wireless charging receiver), the magnetic field of the primary coil should be guided.
2. Magnetic shielding
The magnetic sheet should not only be able to conduct magnetic field effectively, but also play a role of magnetic barrier. Why do you want to block magnetism? We know that when the changing magnetic field meets a metal and other conductors, if the metal is a closed wire, it will generate current; if the metal is an unclosed wire, especially a whole piece of metal, it will produce eddy current effect.
3. Heat dissipation

The magnetic field acts on the inductance coil, making it produce high-frequency current. In this process, the coil itself will produce heat. If the heat is not effectively emitted, it will gather. Sometimes we feel a lot of heat when charging wirelessly. Generally, it is caused by the heating of inductance coil or circuit board.
