10 Layer Stackup
Please modify the variables far and then click on the ‘Calculate’ button. The trace impedance’s will then be calculated.
Note: All values need to be filled to get the desired result.
1. All dimensions are in MIL (thousands of an inch).
2. For microstrip traces (0.1< W/H < 4.0; 1 < Εr < 16 ) where W = width of the trace H = height of the dielectric Εr = Dielectric constant 3. The Dielectric Constant of FR4 material may vary by as much as 20% (4.2 to 5.2). 4. The overall Dielectric Thickness (Cu to Cu) should total 62 MIL nominally. 5. Variables unavailable for modification have no significant effect on the impedance of the traces.
