PCB Specification
In general, your pcb specifications needed to be defined well at initial stage of kicking off project. So you can just list specifications as below with your final gerber files enclosed an engineering confirmation checklist, and all send them out. Your pcb maker will make pcb for you. Please note, pcb manufacturers after receiving gerber, usually a more detailed breakdown of the production of works recognized.

- Mm1 rc3 pcb stack up.png
PCB stack up is made at initial stage of routing. In general this data is defined by customer design side not pcb maker. So if you don't request pcb maker follow a specific stack up, they will use the most popular stack up. You should ask pcb maker to provide this data. For MM1 project, we defined this to let pcb maker follow it.
