|Results for External Layers in Air|
|Requred Trace Width:|
This design tool is based on the charts in IPC-2221.
First, the Area is calculated:
Then, the Width is calculated:
For IPC-2221 internal layers: k = 0.024, b = 0.44, c = 0.725
For IPC-2221 external layers: k = 0.048, b = 0.44, c = 0.725
Note: k, b, and c are constants resulting from curve fitting to the IPC-2221 curves.
The IPC-2221(A) equations are different from those in IPC-D-275 in that they are more conservative and derated to compensate for manufacturing effects.
