Abstract

The invention relates to a wireless charging device, including a packaging shell, a coil and a control circuit. The coil is electrically connected with the control circuit, the coil and the control circuit are packaged in the packaging shell, the control circuit is integrated on a wafer, and the wafer is packaged in the packaging shell. Through integral packaging, the wireless charging device has the characteristics of high integration, simple structure and small volume, the failure rate of the packaged wireless charging device is greatly reduced in a working process, machining of the control circuit is facilitated, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a wireless charging device. Background technique [0002] At present, smart devices such as handheld devices and wearable devices are widely used. In order to meet the needs, these smart devices tend to become thinner and smaller. Therefore, these devices need to be highly integrated. More electronic components are integrated in the space to achieve more functions. With the convenience and humanization of the application of these smart devices, smart devices have gradually added wireless charging functions. Traditional wireless charging uses the separation of inductors and control circuits. design, in which the charging control circuit is composed of PCB (Printed Circuit Board), IC (Integrated Circuit Integrated Circuit), and passive components such as resistors and capacitors. The control circuit is bulky, with various manufacturing processes and complex structures. , prone to ...
