Printed Circuit Board Design and Layout
Questions
- What are the
primary design guidelines that must be
followed when laying out a printed circuit
board?
- How do
differential signals induce common-mode
currents on the cables and structures
attached to a printed circuit
board?
- How "balanced"
does a differential trace pair on a printed
circuit board have to be? (i.e. If the two
trace lengths are within 1 mm of each other,
is that good enough?
- If I have to
route a trace over a gap in a ground plane,
what precautions should I take?
- Should I
always gap the ground plane between analog
and digital circuits?
- Does it matter
if traces are routed along the edge of a
PCB?
- Is it a good
idea to stitch signal return planes together?
