Eurocard is an IEEE standard format for printed circuit board (PCB) cards that can be plugged together into a standard chassis which, in turn, can be mounted in a 19-inch rack. The chassis consists of a series of slotted card guides on the top and bottom, into which the cards are slid so they stand on end, like books on a shelf.
PCB NC drill files convey PCB drilling and routing information. The NC formats were originally designed by CNC drill and route machine vendors as proprietary input formats for their equipment, and are known under their company name: Excellon, Hitachi, Sieb & Meyer, Posalux, etc.
The Gerber format is an open, ASCII, vector format for printed circuit board (PCB) designs. [1] It is the de facto standard used by PCB industry software to describe the printed circuit board images: copper layers, solder mask, legend, drill data, etc. [2] [3] [4] The standard file extension is .GBR or .gbr [1] though other extensions like .GB, .geb or .gerber are also used.
AMC.0 is the "base" or "core" specification. The AdvancedMC definition alone defines a protocol agnostic connector to connect to a carrier card or a backplane. Intermediate revisions are known as engineering change notices, or ECNs. [1] R1.0 adopted January 3, 2005 ECN-001 adopted June 2006
The EMN File contains the PCB outline, the position of the parts, positions of holes and milling, keep out regions and keep in regions. The EMP file contains the outline and height of the parts. Some CAD software allows the use of a map file to load more detailed part models. [2]
The √ 2 factor also appears between the standard pen thicknesses for technical drawings in ISO 9175-1: 0.13, 0.18, 0.25, 0.35, 0.50, 0.70, 1.00, 1.40, and 2.00 mm. This way, the right pen size is available to continue a drawing that has been magnified to a different standard paper size.

ODB++ can handle all the specifications surrounding a PCB – i.e. not only the basic dimensions and the layout of conducting layers and drill data, but optionally also material stack up, netlist with test points, component bill of materials, component placement and fabrication data.
