Wireless charging coil module business opportunities highlight Thanks to the rapid development of wireless charging market, the demand for transmitter (Tx) and receiver (Rx) coil modules has also surged, driving the global coil module shipments soaring, and attracting coil manufacturers at home and abroad to enter the market, intensifying the fierce competition in the coil module market, Fuying coil began to produce wireless charging coil in 2012, so far the shipment has exceeded 80000K As more and more advanced smart phones support wireless charging technology, the demand for coil modules from mobile phone and charging plate equipment manufacturers is increasing. In recent years, coupled with the advent of medium power wireless charging products, high-order coil modules with better coupling efficiency have become the new market favorite, expanding the scale of the wireless charging coil market Coil module is composed of anti-magnetic sheet and copper coil, accounting for nearly 40% of the cost of wireless charging module; Among them, the function of anti-magnetic sheet is to prevent electromagnetic interference from affecting the mobile communication chip, while the coil is responsible for generating or receiving power energy. Both play an important role in the wireless charging module, and the quality has a direct impact on the efficiency of wireless charging At present, a large number of products shipped by Fuying coil are mainly single-coil modules, whose application market covers all the current wireless charging products, followed by multi-coil modules with a wider charging range, but the cost of multi-coil modules is 1.5 times that of single-coil modules, so only in the middle and high-end equipment will use this solution In order to win the future coil factory in the market, it is bound to continue to reduce the cost of anti-magnetic sheet through the new manufacturing process, further reduce the coil width, and adjust the coil coupling efficiency to the best, only in order to have the opportunity to continue to power in the wireless charging coil market.
