PCB의 선폭, 동박의 두께, 길이를 입력하면 저항값을 얻을 수 있다.
Electrical Equations:
Resistance = Resistivity*Length/Area*(1 + (Temp_Co*(Temp – 25))
Where, Area = Thickness*Width
A copper Thickness of 1 oz/ft^2 = 0.0035 cm
Copper Resistivity = 1.7E-6 ohm-cm
Copper Temp_Co = 3.9E-3 ohm/ohm/C
Thermal Equations:
Thermal_Resistance = Thermal_Resistivity*Length/Area
Copper Thermal_Resistivity = 0.249 cm-K/W (at 300K)
