PCB 熱能計算機

PCB 熱量計算器可幫助您估算使用暴露焊盤封裝的元件接點溫度。此工具可根據 PCB 上銅箔的延展面積，快速估算預期接點溫度。

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
