This wire was developed initially for circuit assembly by the wire wrap technique but also serves well for miniature point-to-point wiring on perfboard. Bare copper wire is useful when merging a number of connections to form an electrical bus such as the circuit's ground, and when there is enough space to properly route connections, instead of wiring them rat's-nest style.
This wire was initially intended for circuit assembly using the wire wrapping technique but also works well for connecting components on perfboard in a miniature fashion. Bare copper wire is useful for joining multiple connections into an electrical bus, such as the ground, when there's enough space to route them neatly instead of haphazardly.
