Â
A trace is a group of finite-sized planar objects that have the same conductive properties and same Z-coordinate. In other words, they are located on the same horizontal plane, or at the same vertical level on the layer stack-up. You can define two types of metallic traces in the [[Planar Module]]:
Â
# '''PEC Traces:''' These represent perfect conductor objects that have zero thickness and no editable material properties.
# '''Conductive Sheet Traces:''' These represent imperfect metal objects. They have a very small finite thickness t and a finite conductivity s.
