![]() If your PCB manufacturer uses different PCB design software, you have to generate Gerber files by yourself, further conversation and confirmation will definitely cause more time and delay the production process accordingly.Įven if PCB manufacturer uses the same PCB design software as you do, you are still advised to generate Gerber files on your own since difference in terms of applied software may also lead to possible errors. You are hardly able to make sure the PCB design software you're using is the same as that is being used by your PCB manufacturer. PCB design engineers should never be too lazy to generate their own Gerber files for the following two reasons. When it comes to PCB assembly, a stencil layer is included in Gerber format and component locations are regulated as well, which will be regarded as significant reference data for SMT (Surface Mount Technology) assembly, thru-hole assembly and mix of them. put it simply, Gerber format files have to be depended from beginning to the end of PCB fabrication process. 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.
