Burr
A burr refers to a small, unwanted raised edge or sharp projection left behind on the surface of a PCB after machining processes like drilling, routing, or milling. Burrs may be caused by dull or chipped cutting tools, improper drilling or routing parameters, or material delamination. While seemingly minor, if left unchecked burrs may cause electrical shorts, component placement issues, or assembly damage.
