Thermal design requirements for mobile phone wireless charging

       With the maturity of mobile phone wireless charging technology, more and more mobile phones use wireless charging technology as a product selling point to attract consumers. In the design of mobile phone wireless charging circuit board, it is the most important to consider and meet the thermal design requirements of mobile phone wireless charging circuit board. This can not be ignored whether it is layout or wiring.

Thermal design requirements for mobile phone wireless charging circuit board：

1. When arranging the components, the temperature sensitive components other than the temperature detection components shall be placed close to the air inlet and at the upstream of the air duct of the components with high power and high calorific value. They shall be kept away from the components with high calorific value as far as possible to avoid the impact of radiation. If they cannot be kept away, they can also be separated by thermal shielding.

2. Place the heating and heat-resistant devices close to the air outlet or on the top, but if they can not withstand high temperature, they should also be placed near the air inlet, and pay attention to staggering with other heating devices and thermal sensors in the rising direction of the air.

3 . High power components shall be distributed as far as possible to avoid centralized heat source; Components and parts of different sizes shall be arranged evenly as far as possible, so that the wind resistance and air volume are evenly distributed.

4. The higher device shall be placed behind the lower device, and the long direction is arranged along the direction with the minimum wind resistance to prevent the air duct from being blocked.

        Wireless charging technology breaks the traditional connection line charging. It is a wireless charging technology using intelligent power transmission, which improves the efficiency and convenience of charging; In recent years, mobile phone wireless charging has been widely recognized and its utilization rate is getting higher and higher. It once became a popular product in the mobile phone charging industry.
