PCB 热量计算器

PCB 热量计算器可帮助您估算使用外露焊盘封装的元件的结温。该工具会根据 PCB 上的覆铜面积对预期结温进行快速估算。

0.3 °C/W
Thermal resistance from the junction of the device to the exposed pad on the bottom of the device.
 W  °C
Ambient = air temperature away from system/device (not heated by the system)
Board = temperature of the board 1mm away from the device
 
 

Temperature vs. PCB copper coverage area

Enhanced Thermal = single thermal spreading plane of 1 oz Cu
Minimum Thermal = single thermal spreading plane of 1/2 oz Cu
