Hello ,
To PCB manufaturer, they just need the files you want PCB like.
normally, you need to output below files:
1. circuit layers, such as GTL,GBL for outer layer, if it is multilayer PCB , you should also output all inner circuit layers, such as GND, vcc, inner layer 1, inner layer 2 and so on.
2. solder mask layer: Such as GTS,GBS
3. components marks/ silkscreen layer, such as GTO, GBO
4. Drill holes : such as drill
5. drill drawing
6. if you need carbon or peelable mask to be printed on PCB , you also need to outgoing carbon or peelable mask layer.
Any questions related to PCB manufacturing process , you can ask me.
hoping my words above can help you out .
