![]() When it comes to bare board fabrication, Gerber format is called for by both standard photoplotters and other manufacturing equipment desiring image data like legend printers, direct imagers or AOI (Automated/Automatic Optical Inspection) equipment etc. Gerber format file is applied to describe design requirement of each image of a circuit board and it can be applied for both bare board fabrication and PCB assembly. ![]() PCB manufacturers won't fully understand all details of a PCB design file unless Gerber format file is contained in it as reference and guidelines. Printed circuit boards are designed in a specialized EDA (Electronic Design Automation) or a CAD (Computer-Aided Design) system that further generate board manufacturing data based on which circuit board fabrications are commenced. Initially developed by a company with the name of Gerber, Gerber format currently refers to a widely accepted standard PCB industry software sticks to, capable of describing circumstances of board images such as conductor layers, soldermask layers, legend layers.
