What is/how to "cut tracks" on vero layouts?

[debutvm]

I see the red square symbol on the vero layouts mean to cut a track. This is a very noob question, but how do you cut the track, and also why do you do it?

[Connoisseur of Distortion]

it's exactly what it sounds like: you break the track.

The idea is that the tracks will allow for continuity between your components, and that you can place components in the holes and attach them to a track. Now, if we had to keep every single track dedicated to a single node (common term for a place where two or more components connect), our veroboards would be massive!

To cut a track will allow another node to be made on the other side of that cut. If it was not cut, you would have the two nodes touching, and your circuit would do some mysterious things... like not work...

When cutting tracks, be sure to COMPLETELY separate the track, because any connection will allow a current to flow across it. Also, the shredded metal that you just ground off will often end up sticking outwards, and may touch an adjacent trace; even though you didn't grind on that other track, it can still cause you misery.

It's best to use a multimeter to test for continuity. You don't have to see the bridge for it to ruin your build! 

Best of luck!

There used to be a special tool to cut tracks - these days I use a 3mm drill bit between the fingers to cut away the copper track (just don't go too deep).

That's a tool like the one on this picture.

What makes it better than a drill is that it is faster.



Btw, here is a little info about the veroboard. It should help you.

I just cut it with sharp tool at both side of hole and test both cuts with DMM.
