Is substrate thickness specified in the Gerber file?

Hi, I am trying to manufacture several 2-layer boards on FR4 with different thicknesses.



0.8mm, 0.4mm etc. My software (Eagle from Cadsoft) lets me specify substrate thickness in the design rules. However, I can't find any trace of the this info in the produced Gerber files. Is substrate thickness supposed to be in the gerbers, or supplied separately?

Thanks, Pavel

You have to specify the board thickness separately. You may also have to list the drill tool codes and associated hole sizes.

Your artwork should have a thin track on at least one copper layer showing the desired outline of the board.

A previous, related thread:

They let you continue to type on a line all the way over, but when they post it, they break that line by inserting a carriage return after ~72 characters.

Your submission may thus look choppier than you expected.
