The following footprint naming conventions should be used as examples for naming SMD chip package footprints.
If you do not find an appropriate convention that matches a particular footprint type, either contact the KiCad library team or try to match a convention set by existing library components.
In the entries below, variable fields are denoted as follows:
- Fixed fields
- Mandatory fields
- Optional fields
- Prefix - Device type
- Imperial size - Imperial case size (Optional)
- Metric size - Metric case size (Optional)
- Modifiers - Modifiers to footprint if non standard (Optional)
- Options - Extra footprint options (Optional)
Example:
Notes:
The prefix is determined by the default reference designator of the device, e.g.
-
Capacitor =
C -
Capacitor (polarised) =
CP -
Resistor =
R -
Diode =
D
