Today, small series continues to be popular for the types of wireless charging coil characteristics. The first is to understand the mobile phone wireless charging coil, wireless charging coil in the phone must be followed by magnetic separation material, there are sub inorganic magnetic materials.
For example, PC44 and organic materials, such as micro aerial wireless charging machine type antenna. Is inorganic, sintering process, easily broken, not suitable for the mobile phone attached to the shell, because it is easy to damage, and a plane Dongdong 40mm diameter, installed in the surface of the shell, is not appropriate. So this kind of inorganic material can only find space on the circuit board. The organic magnetic material can be bent, four corners have positioning holes, the inner side of the mobile phone shell can extend the plastic positioning support, card in the positioning hole, so good installation. Then, the antenna to determine the number of laps, the antenna manufacturers need to take the terminal to test, debug the best parameters, making the charging efficiency is high. This is the same as the mobile phone with the built-in antenna process. Wireless charging technology in 2013 after a large number of popular, we will believe that it will be obvious to all of us.
