sot23 using recommended footprint drawing

Generate a sot23 footprint mainly from recommended footprint (copper pad) drawing, optionally also using component drawing for silk, assembly and courtyard layers

name man
dat
ory		description value (bold: default)
N yes number of leads
3
4
5
6
8
PW yes pad width Dimension: a number with an optional unit (mm or mil, default is mil)
PL yes pad length Dimension: a number with an optional unit (mm or mil, default is mil)
PRP yes pad row pitch: distance between center of pads of the two rows Dimension: a number with an optional unit (mm or mil, default is mil)
PP yes nominal pitch (computed assuming no missing leads, so 6 or 8 leads) Dimension: a number with an optional unit (mm or mil, default is mil)
Default: 0.95
BL   plastic body length (with tolernace)  
BW   plastic body width (with tolernace)  
PE   pin extent (with tolernace)  
PT   pin thickness (with tolernace); really the width of the lead  
PC   pin contact length (with tolernace); specify either this or PG  
PG   pin gap (with tolernace); specify either this or PC  
datasheet   url to the datasheet dimensions are coming from  
F yes fab tolerance in +-mm  
P yes part placement tolerance in +-mm  
silk_thickness yes thickness of silk graphic lines; diametr of pin 1 dot is calculated from this too  
mask_offs yes gap between copper pad edge and mask cutout edge  
glue_thick yes default line thickness for glue on adhesive layers; if 0 omit the layer  
glue_dots yes print dots instead of lines for glue when non-zero  
pad_rounding   rectangular pad corner rounding radius (0 for sharp corners) Dimension: a number with an optional unit (mm or mil, default is mil)
