“Artwork”
is used to define the size and shape of solder
|
|
|
connects
for components like capacitors, diodes, RF chips,
|
|
|
etc.
|
|
|
| • |
The
dimensions of solder pads (where you actually connect
|
|
your
circuit) are specified on data sheets.
They are also
|
|
|
available
in the libra “library” for many standard elements.
|
|
|
| • |
The
size of pads add length to your lines, so you will need
|
|
|
to
include them in your simulation for most accurate
|
|
|
results. This means you need to figure out their
size before
|
|
|
you
simulate the circuit, so you will do some back-and-
|
|
|
forth
between layout and simulation.
