# Référence d'Empreintes

Le document maître pour la création d'empreintes est le PCB Manual. Il y a aussi le Footprint Creation for the Open-Source Layout Program PCB de Stuart Brorson.

## Syntaxe Générale

Un fichier d'empreinte pcb peut contenir une des commandes suivantes:

- `Element [element_flags, description, pcb-name, value, mark_x, mark_y, text_x, text_y, text_direction, text_scale, text_flags]`
- `Pad [x1 y1 x2 y2 thickness clearance mask name pad_number flags]`
- `Pin [x y thickness clearance mask drillholedia name number flags]`
- `ElementArc [x y r1 r2 startangle sweepangle thickness]`
- `ElementLine [x1 y1 x2 y2 thickness] –> thickness != 1000 = 10 mils almost for all footprints`
- Les lignes de commentaires débutent avec le signe ‘`#`’

## Éléments

`Element [element_flags, description, pcb-name, value, mark_x, mark_y, text_x, text_y, text_direction, text_scale, text_flags]`

item | allowed value | explanation | comment
--- | --- | --- | ---
element_flags | unsigned hex value |  |
description | string | text descriptif de l'empreinte | écrit par l'auteur de l'empreinte
pcb name | string | refdes utilisé pour ce pcb particulier | xxx
value | string | valeur du composant sur ce pcb particulier | xxx
mark_x | 1/100th mils |  |
mark_y | 1/100th mils |  |
text_x | 1/100th mils |  |
text_y | 1/100th mils |  |
text direction | decimal integer | 0=horiz; 1=ccw90; 2=180; 3=cw90 |
text_scale | decimal integer |  | usu. set 100
text_flags | unsigned hex |  |

## Pastilles

`Pad[x1 y1 x2 y2 thickness clearance mask name pad_number flags]`

Item | Allowed Value | Explanation | Comment
--- | --- | --- | ---
x1 | 1/100th mils | x(1st point) |
y1 | 1/100th mils | y(1st point) |
x2 | 1/100th mils | x(2nd point) |
y2 | 1/100th mils | y(2nd point) |
thickness | 1/100 mils | épaisseur de métal entourant le segment de ligne | voir le .pdf de Brorson
clearance | 1/100 mils | distance vis à vis des autres zones de cuivre sur toutes les couches | actually 1/2 of this number is used!
mask | 1/100th mils | width of mask relief | actual width of the mask centered on pad copper
name | string | name of pad (arb. string) | e.g. “pad_1” or “positive” or any other string
pad_number | string | pad # | used for nets. it MUST be consistent with the definitions on the netlist.
flags | hex value | xxx |

## Broches

`Pin[x y thickness clearance mask drillholedia name number flags]`

Item | Allowed Value | Explanation | Comment
--- | --- | --- | ---
x | 1/100th mils | pin x coord. |
y | 1/100th mils | pin y coord. |
thickness | 1/100th mils | copper diameter |
clearance | 1/100th mils | 2*(cu to cu clearance) | if you want a 10 mil clearance, put 2000 (20 mils) here
mask | 1/100th mils | diameter of mask aperture | actual dia. of hole in mask
drillholedia | 1/100th mils | dia. of hole |
name | string | arb. pin name |
number | decimal integer | pin number used by nets/rats |
flags | hex | xxx |
