Board Quantity
The quantity of the board you needed
≥5pcs
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
