Wireless charging coil module business opportunities are highlighted. Benefiting from the rapid development of the wireless charging market, the demand for transmitter (Tx) and receiver (Rx) coil modules has also surged, driving the global coil module shipments to soar while attracting domestic and international coil manufacturers to enter the market, intensifying the intense competition in the coil module market.
With increasingly high-end smartphones supporting wireless charging technology, the demand for coil modules from cell phone and charging board device manufacturers is increasing daily. With the introduction of mid-power wireless charging products in recent years, higher-end coil modules with better coupling efficiency have become a new market favorite, expanding the wireless charging coil market.
The coil module is composed of an antimagnetic sheet and a copper coil, accounting for nearly 40% of the cost of the wireless charging module; among them, the function of the antimagnetic sheet is to prevent electromagnetic interference from affecting the mobile communication chip, while the coil is responsible for generating or receiving power energy, both of which play a pivotal role in the wireless charging module. Their quality directly affects the efficiency of wireless charging.
Currently, the single coil module application market covers all wireless charging products today, followed by a broader range of charging multi-coil modules. Still, a multi-coil module costs 1.5 times that of a single-coil module, so only high-end equipment will be used in this solution. To win in the market in the future, coil manufacturers must continue to reduce the cost of antimagnetic sheets through new processes, further reduce the width of the coil, and at the same time, adjust the coil coupling efficiency to the best to have the opportunity to continue to force in the wireless charging coil market.
