Nope. That's the maximum *signal* rate of change for a sinewave. I

Is there an easy way to get a layout print similar to PCB's fab.ps but
showing the part number/value (what PCB calls the value, and doesn't
seem to use except in the BOM outputs)? I'm thinking that something
made from the .xy file, printing those values rotated and placed would
be close enough.
Unfortunately, this bit me on a board with a top-side ground plane, and
I didn't catch it until I got the boards back (1) ... perhaps because
much of the erroneous copper was lost in that plane.
What I've found - just did a simple test case that shows it - is that
if one has a copper legend (text

This may just be me being up later than I should be working on this,
but I can't find a clue just now: can PCB be asked to print just the

become needless waste paper as soon as they come out of the printer?
How about getting it
