I've looked around and google and on this forum and can't quite find the answer to my question so here goes.
I know that conventional method for installation of resistors is parallel with the board. I can see why. It makes identifying the resistor and troubleshooting problems easier.
But I need to conserve space in my design and I have seen on a few instructables people with resistor installations like the one on the right in the picture.
Is there a specific reason for this other than it saves space? I would very much like to do this. Any reason why I couldn't?
