[sdiy] PCB layout tips

[harrybissell]

Otoh I'd rather cross the power runs with a signal jumper... or
a resistor, cap, diode, all of which make fine jumpers.

Power runs almost always go to all chips, so those are the largest
nets and its easier to not have extra breaks in them.

For the newbies on this list... it prolly does not matter if you follow
Ken's way or mine... the number of jumpers is probably the same anyway.

And if its a double sided layout... there aren't any jumpers anyway.
