Wireless charging is divided into a transmitting end and a receiving end. The transmitting end includes a chip, an oscillator, a power amplifier, a coil, a PCB, a passive device, an electronic transformer, a structural member, etc.; the receiving end can be further divided into two parts: a chip and a module. Regardless of the transmitting end or the receiving end, the industrial chain mainly includes several aspects such as scheme design, power chip, magnetic material, transmission coil, and module manufacturing.

Since the size and material of the transmitting end (charging board) are not limited, the barriers are very low, and many manufacturers can be made. The technical content and added value of the transmitter module manufacturing are relatively low, which is the easiest link. Lixun Precision, Xinwei Communication, Shuobeide, Sunlord Electronics and many foundries can complete it.
Under the trend of thin and light smartphones, the internal space of mobile phones is getting smaller and smaller, and the integration of components is getting higher and higher. The design of mobile phone parts manufacturers and the level of integrated manufacturing are all higher requirements. The receiving end module requires small size and high integration. The design must take into account the internal electromagnetic compatibility of the mobile phone, and also consider the design of the mobile phone casing, so it is difficult to design and manufacture.
In terms of receiver module manufacturing, Dongshan Precision (acquisition of M-Flex), Fujikura (Fujikura), and Hanhua Technology are suppliers of Apple receivers. Tony Electronics (License Precision is its shareholder) is likely to meet next year. Intervention; Xinwei Communication, Shanghai Amphenol No. 100 is Samsung's receiver supplier, and Amphenol is mainly domestic customers; Sunlord Electronics has the ability to wind and FPC wireless charging and receiving coils, which has been given to domestic such as Huawei Such as brand supply; in 2014, the Shuobeide wireless charging receiving and transmitting products are in the small-batch shipment stage; Weihang has developed an ultra-thin wireless charging coil (only 0.4mm thick) and circuit components.
Below, Xiaobian will briefly introduce these wireless charging receiver module enterprises.
