melf-ipc parameters

Ordered list (positions): density,PE,PD,PC,PG

name man
dat
ory		description value (bold: default)
density yes board density; C=high density, B=moderate density, A=general (low density)  
PE   pin extent (with tolernace)  
PD yes pin diameter (with tolernace); really the width of the lead  
PC yes 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)
