Track (trace)
A copper line of a chosen width joining pads of one net.
How it looks
Real image: CORE3588, rendered by KiCad from our board file
Tracks on CORE3588, top side, 6 x 5 mm. Olive = copper under the green coating; darker green = no copper underneath.
- 1A thin signal track (0.2 mm): the light olive line under the green coating is copper.
- 2It ends on a round copper pad (a test point).
- 3Tracks turn in 45 degree steps, never sharp right angles.
Real geometry: CORE3588 copper, drawn from our board file (2D plan view)
Width is chosen per job. Real CORE3588 copper drawn flat: the amber power track is 7 times wider than the signal tracks beside it.
- 1The main 4 volt power track: 1.5 mm wide, to carry a lot of current.
- 2A signal track next to it: 0.2 mm.
How it works
Where it fits
A track belongs to one net, runs on one layer, and changes layer through a via. Routing means drawing all of them; Ants does that.
