Good Engineering Practices

[Bob Zimmer]

To all,

I keep hearing and reading about "Good Engineering Practices".  Short of
taking the next five years off to get an EE degree, could we open a
discussion about this topic where some can relate on their experiences?

Some of what I've accumulated is:

1.  Put a large electrolytic 100 uF or larger on all supply lines to
stabilize     the power distribution.

2.  Put .1 uF bypass (spelled ceramic disc) capacitors at various locations
(near power connections to op amps and digital ICs) to control noise.

3.  Have board input and output lines well separated to control crosstalk
and     S/N ratios.

4.  Design "guard" circuits around the inputs to high quality opamps and other
    "special" components.

What are some of the other practices that one should follow when designing
PC boards?
