Similar to the last is a jumper location that is connected by copper by default to be cut if an open is needed. Consider this to be a 1 bit PROM.A similar "track is component" scenario: PCB fuse track - a dirty trick I've seen in some Honywell boiler controllers.. where a deliberately thin trace is used to act as a fuse.That certainly is a dirty trick! (But on a very tight budget it could make sense). So there are several use cases for treating copper as non-connecting: * low value resistors * fuses * low value inductors * aerials * contacts for solder switches (eg SPDT in solder)
