I'm currently working on a PCB for work so in an attempt to learn the best techniques/tricks I was looking at an old (2001) video card. One thing I noticed was there is a lot of little zig-zagged traces. I'm just wondering why someone would do that? My guess is it increases the length of the trace, thus increasing capacitance with the ground plane, as well as resistance. So would this be used for a low current DC line? Or maybe is it some sort of noise removal technique?
There is a whole bunch of them on the left side of this image: http://www.smye-holland.com/SmyeHolland_ImageLibrary/Copy of Printed circuit board.jpg
