While I was idly scrutinising a motherboard out of a recent model computer I noticed something peculiar about the PCB tracks.
Many of them have been routed deliberatly to make them as long as possible. They have 'wiggles' and S-bends, switchbacks and detours all over the available area to lenghten the track.
I would have thought that the very high data transfer speeds these days demand tracks as short as possible. So why is it that 30% or so of the tracks on this board are very much longer than the direct route?
curious,
Klaus
