Wireless charging technology originates from wireless power transmission technology. This technology breaks the traditional charging with connection line, improves the efficiency and convenience of charging.The utilization of wireless charging technology is increasing. Due to the small volume of the device, the working temperature of the internal electronic components must be solved. Thermal conductive like graphite sheet and silicone pad and other heat dissipating materials can provide a complete set of heat dissipation scheme for the research and development of wireless charger. The heat dissipating materials can solve the heat accumulation of electromagnetic wave emitter in the closed space.
