line Min Trace width 3mils(1oz Finish Cu) 4/4mil(copper thickness 1 OZ),5/5mil(copper thickness 2 OZ),8/8mil(copper thickness 3 OZ),It is recommended to increase the line width and line spacing if conditions permit
Min Trace space 3mils(1oz finish Cu) 4/4mil(copper thickness 1 OZ),5/5mil(copper thickness 2 OZ),8/8mil(copper thickness 3 OZ),It is recommended to increase the line width and line spacing if conditions permit
Line to board edge distance ≥0.3mm(12mil) CNC:≥0.3mm V-cut:≥0.4mm
Copper weight Copper weight for Internal layer 1/3-14OZ Refers to the connecting line width of two copper sheets in the line
Copper weight for External layer 1/3-12OZ Refers to the thickness of the copper foil of the outer circuit of the finished circuit board
Special process Special production process   Resin plug hole, pan hole, Rogers mixed pressing plate, blind hole, bonding IC (special process needs to be reviewed first), blue glue, red tape
character Aspect ratio of character 1:5 Suitable ratio of width and height, more conducive to production
Character height ≥0.8mm The minimum height of characters. If it is less than 0.8mm, the characters of the physical board may not be clear due to design reasons
Character width ≥0.1mm The minimum width of characters. If it is less than 0.6mm, the physical board may cause unclear characters due to design reasons
