Abstract

The present invention discloses a charging coil and a manufacturing method thereof. The charging coil comprises a substrate having at least one set of conducting and connecting holes; at least one coil structure formed on the substrate, wherein the two end points of each coil structure are connected with one set of conducting and connecting holes; a supporting layer formed at the gaps and the peripheries of the coil structures to support the coil structures. According to the present invention, a lithography technology is applied to manufacture, thereby obtaining the charging coil which realizes a single place and has the largest number of turns and the thinnest thickness, and realizing the technical effects of simple process and high yield.

Description

technical field [0001] The present invention relates to a substrate, in particular to a charging coil and a manufacturing method thereof. Background technique [0002] At present, wireless charging technology is gradually penetrating into various fields, such as mobile devices, computers and other electronic products, other electronic products, electric vehicles, and even mobile wearable devices such as electronic shoes and electronic clothing. In the future, if the charging efficiency problem of wireless charging technology can be solved, wireless charging technology may become the mainstream of charging in the future. [0003] At present, there are mainly four types of wireless charging technologies, Inductive Coupling, Resonant Coupling, Microwave Power Transfer and Laser Power Transfer. At this stage, magnetic induction and magnetic resonance are relatively mature wireless charging technologies. These two wireless charging technologies must be equipped with charging coi...
