Specification Introduction Capabilities
Board Layers The quantity of the copper layer in your design 1-12layer
Board Quantity
The quantity of the board you needed
Solder Mask Color The color of your board Green/Red/Black/White/Blue/Yellow
Silkscreen Color The color of the silkscreen texts on your board White for Green/Red/Black/Blue color board Black for White/Yellow color board
Board Dimension Single pcs rectangle PCB board
circle PCB board
Max size:540mm*540mm
Min size: 2mm*2mm
Tolerance: ±0.20mm

Ps. If your board dimension is so small, would better make a bigger panel and use slots to separate the board.
