Thermal Pad WT5912-H20，WT5912-H25 Provides a Heat Dissipation Solution for Wireless Charger
Wireless charging is a device that uses the principle of electromagnetic induction to charge. By placing a coil on each of the transmitting and receiving ends, the transmitting end coil emits an electromagnetic signal to the outside under the action of electric power, and the receiving end coil receives the electromagnetic signal and converts the electromagnetic signal into Current to achieve wireless charging.
The wireless charging technology has broken through the shackles of the traditional charging line, and the usage rate is getting higher and higher. The wireless charger has once become an explosive product in the mobile phone charging industry. However, due to the small size, the operating temperature of the internal electronic components needs to be solved, and the thermal pad provides a heat dissipation solution.

For higher efficiency heat dissipation, the bottom of the wireless charging is usually an integrated metal material with a thermal anti-skid pad, which can lay a good foundation for the internal electronic components to dissipate heat, and can also play the role of anti-slip and wear.
Connected to the bottom case is a wireless charging circuit board. All components are concentrated on one side of the PCB. Since the circuit boards are irregularly integrated, they cannot be directly connected to the bottom case. So the thermal pad is usually attached in the bottom case to fill the gap between the bottom case and the circuit board, so that the heat of the circuit board is guided to the bottom case through the thermal pad to dissipate heat, and also functions as an electromagnetic barrier.
