External copper weight
0.7 oz to 3 oz(25μm to 140μm) The default thickness of normal PCB's copper is 1oz, the maximal thickness is 3oz 
Internal copper weight0.5oz(17μm)All of the PCB's internal copper's thickness
Min Hold Size
0.1 mm
The minimal via diameter is 0.1mm
Min Tracking

1.57 mil

(0.04 mm)

(0.002'')


the minimal width is 1.57 mil
Min Spacing

1.57 mil

(0.04 mm)

(0.002'')

the minimal width of gap is 1.57 mil
Accuracy of boundary dimension±0.2mm
Tolerance of board's boundary is ±0.2mm 

Tolerance of board's thickness(T≥1.0mm)
±10%For example: T=1.6mm, the real thickness is ranged from 1.44mm(T-1.6*10%) to 1.76mm(T+1.6*10%)
Tolerance of board's thickness(T<1.0mm)±0.1mm For example: T=0.8mm, the real thickness is 0.7mm(T-0.1) to 0.9mm(T+0.1).
The tolerance of bore diameter
±0.08mmFor example: the designed bore diameter is 0.6mm, then the real bore diameter is allowed range from 0.52mm to 0.68mm
Minimal width of character
6milThe character will be blurry if the width of character is less than 6mil
Distance between routign and boundary
≥0.3mmGong plate: the distance should more than 0.3mm; V-cut: the distance shoud more than 0.4mm 
Jointed board(no gap)
No gap jointed boardThe gap between the jointed board is 0mm
Jointed board(has gap)
The gap between jointed board is 2.0mmThe gap between jointed board don't be less than 2.0mm, or it's difficult to Gong the boundary
Minimal diameter of half hole process
0.6mmHalf hole process is a kind of special technology, the minimal diameter is 0.6mm
Solder window
0.1mmSolder resist means paint the oil
