Abstract: A substrate of a circuit board and a substrate of a charging coil are disposed at a same layer, a first wiring layer and a first coil are disposed at a same layer, and a second wiring layer and a second coil are disposed at a same layer, so that the charging coil and the circuit board form an integrated structure. The first coil and the second coil may be directly electrically connected to a wire on the circuit board, for example, a wire at the first wiring layer of the circuit board or a wire at the second wiring layer of the circuit board. This can shorten a charging path between the charging coil and a load, to reduce a link loss. In addition, a BTB connector can be omitted, to simplify a structure of a charging coil module, and reduce costs of the charging coil module.

Abstract: Disclosed are an antibody-drug conjugate (ADC), an intermediate thereof, a preparation method therefor and an application thereof. The present invention provides an ADC. A structural general formula thereof is Ab-(L3-L2-L1-D)m. The ADC has better biological activity, stability, and uniformity, has reduced toxic and side effects, and has a faster release rate of enzyme cutting in tumor cells. The use of the novel ADC can achieve a wide application of a cytotoxic drug particularly camptothecin in the field of ADCs in treating tumor patients resistant to microtubule ADC.
