🚫 Clearance isn’t creepage These two terms can be confusing, and they are. We need to remember that the shorter distance is the air distance = creepage. while the longer, the surface distance, is creepage. Just when we want to walk the surface of the PCB between two points. Creepage refers to the distance along the surface of the insulating material, while clearance is the shortest air distance between conductors.
