Comparison of Common Terms and Terms in GC-CAM Software

Absolute Data: Absolute data. The position parameters of PCB data are measured with the zero point of the system as the reference.
Absolute X, Y: Absolute coordinates, the coordinate position of the current cursor in the absolute coordinate system.
Aperture: Aperture, the name comes from the early vector photoplotter. In the vector photoplotter, the graphics are formed by light exposing the photosensitive material (film) through the "aperture" holes of different shapes and sizes on the "aperture disk".
Aperture list:

Aperture list Editor: Aperture list editor.
Aperture list windows: Aperture list windows.
Annular ring: Welding ring.
Array: Assembling or display.
Acid trip: Etching dead corner.
Assemby: Installation.

Bare Bxnel: Bare board, PCB board that has not undergone the plug-in process.
Bad Badsize: Workbench, effective size of the workbench.
Bill of Matrials (BOM): Bill of Materials.
Blind Buried via: Blind hole, buried hole.
Chamfer: Chamfer.
Circuit: Circuit.

Circuit layer: Circuit layer.
Clamshell tester: Double-sided tester.
Coordinates Area: Coordinates Area.
Copy-protect key: Software Dog.
Coutour: Outline.
Draw: A circular aperture, but it is only used to create lines, not pads.
Drill Rack: Lead table.

Drill Rack Editor: Lead table editor.
Drill Rack window: Lead table window.
D Code: Code that is not used to express apertures in Gerber format.
Double-sided Biard: Double-sided Biard.
End of Block character (EOB): Block end character.
Extract Netlist: Extract network.

Firdacial: Position mark.
Flash: Pad, originated from early vector photoplotters. In vector photoplotters, pads are formed by light "flashing" through the aperture.
Gerber Data: The most commonly used data format from PCB CAD system to PCB production process.

Grid: Grid.
Graphical Editor: Graphic Editor.
