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 standard security provided by PDF consists of two different methods and two different passwords: a user password, which encrypts the file and prevents opening, and an owner password, which specifies operations that should be restricted even when the document is decrypted, which can include modifying, printing, or copying text and graphics ...
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.
The format was devised by David Kehmeier at the Mentor Graphics Corporation. [1] 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.
IEEE 200-1975 or "Standard Reference Designations for Electrical and Electronics Parts and Equipments" is a standard that was used to define referencing naming systems for collections of electronic equipment. IEEE 200 was ratified in 1975. The IEEE renewed the standard in the 1990s, but withdrew it from active support shortly thereafter.
MEI – Music Encoding Initiative file format that attempts to encode all musical notations; MIDI – MIDI file format that is a music sheet for instruments; MUS, MUSX – Finale sheet music file; MXL, XML – MusicXML standard sheet music exchange format; MSCX, MSCZ – MuseScore sheet music file; SMDL – Standard Music Description Language ...
ODB++ is a proprietary format controlled by Valor later Mentor and now Siemens, and so, like all proprietary standards, it comes with the risk of vendor lock-in. CAD companies had some concerns about this when ODB++ was controlled by Valor, a CAM company, but these concerns were magnified when a rival CAD company, Mentor, acquired Valor. [ 16 ]
