一个PCB相关的计算器,推荐给大家,包括特征阻抗计算、过孔导线温升载流计算等,温升的计算采用最近的IPC2152标准。
Program includes:
PCB Via Current Calculator per IPC-2152
Calculates the current a via needs to raise its temperature over ambient per IPC-2152.
Other via properties include:
Via capacitance
Via inductance
Via impedance
Via step response
Via DC resistance
Via impedance
Via resonant frequency
PCB Trace Width Calculator & PCB Trace Resistance Calculator per IPC-2152
Calculates the current a conductor needs to raise its temperature over ambient
per IPC-2152. Now also calculates DC resistance with temperature compensation.
Other conductor properties include:
Conductor skin depth
Conductor voltage drop
Conductor DC resistance
