Design parametersmin. value
trackwidth/-space:0,150mm (6mil) - standard
 \n 0,100mm (4mil) - surcharge*\n
*You can adjust trackwidth/-space in the tab "Clearance".

Via diameter:0,300mm (12mil)
Annular ring for PTH-drills:0,150mm (6mil) for outer layers
Marking print line width:0,180mm (7mil)
Solder-stop clearance:0,075mm (3mil) - standard
 \n 0,050mm (2mil) possibly needed for Finepitch SMD / BGAs*\n
*You can adjust the solderstop-clearance in the tab "Masks".

\n Polygons need to be filled with a line width of min. 0,200mm (8mil).
\n Text within copper needs a min. width of 0,200mm (8mil). Please active vector fonts.\n
