This is a link to online calculation.
The price is related to PCB area, PCB layers, copper deposition, gold plating or lead-free tin spraying and lead-gold deposition. There is also the need for flying needle testing.
Also, the general thickness of PCB is 0.8, 1.0, 1.2, 1.6, 2.0. If it is of the opposite thickness, the price will be more expensive.
Generally close to 400 square meters, double layer.
I calculated for you, 10* 10CM double panel, lead-free tin spraying, green oil in the hole, no need to fly needle test, 1 ounce copper belly, SF Express arrived home, about 400.
