This option is set for how many circuit layers in your design. Please try to design your board with fewer circuit layers because multi-layer board is not cheap.

As in My Gerber Files
If you require panelized PCBs, you can either define it by yourself in your Gerber file or we can help you define it (for our help please select, “Custom”).
The standard FR4 Tg is between 130 – 140°C, the median Tg is 150 °C and the high Tg is greater than 170°C. In the hot state, high Tg FR4 will have better mechanical and chemical resistance to heat and moisture than standard FR4.
Board thickness tolerance is +/-10%. Solder mask and copper plating will make the boards thicker.
Solder Mask Color
Note: The silkscreen color is white for all solder mask colors except the white solder mask. For white solder masks, the silkscreen is black.
This parameter is for the Top/Bottom layer circuits’ copper weight.
HASL (Lead Free)
ENIG (Immersion Gold)
Extra process to exposed copper to help solderability.
The minimum width of the trace /space in your PCB.
Min. Hole Size
The minimum drilling size of the hole in your PCB.
