Component Placements - this is not used by the bare board manufacturer but is used for DRC checking and for generating pick and place files.
You can see that there is a lot of data to send from design to manufacturing and often the data that is transmitted is incomplete, inconsistent or just plain incorrect.
So the first thing the board manufacturer does is to import all the different data formats and bring the data up in his CAM software. He then checks the data and runs a series of tests to insure that the board can be manufactured. If he finds violations such as traces too close, pads to small for the drill hole or other related problems he can either fix them or report them back to the designer.
It does not insure, of itself, that the data is correct or manufacturable but it does allow the board manufacturer to load all the data at once and immediately run the tests necessary to determine that it is consistent and buildable.
However it is also possible to use other zip formats as long as the hierarchy folder structure is preserved. Conductor and Masks and Silkscreens - this data is located in the layers section. Each conductor has its own directory and a features file that contains the actual entities. The equivalent of Gerber flashes are referenced from the symbol section.
Drill - drills are treated similar to conductors and located in the layer section. The tools file contains a list of the drill tool i. There is also the possiblity to place additional EDA style netlists in the EDA folder but this data is unique to each PCB layout design tool and so the manufacturer generally does not attempt to read it.

This compact self-contained viewer allows you to view standard X format Gerber plotting documents. This viewer can also be used to view older D format Gerber plotting documents.
Select the desired Operating System button above to begin the download. Please note that the FREE mode of the viewer is limited to handling smaller file capacity and simultaneous viewing of two layers.
For increased capabilities the user can upgrade to the Professional Version. A Serial Number is not required to run this software in Lite Mode. Skip to content List of best free Gerber Viewer software to view Gerber files on Windows using various tools.
I've summarized the data and its function below: Gerber Files - these are actually 'CNC' files which drive a photoplotter which creates the film used to expose each conductor layer in the board.
Routing Files - similar to drill files but defines a path for routing out the board. Importing and Checking You can see that there is a lot of data to send from design to manufacturing and often the data that is transmitted is incomplete, inconsistent or just plain incorrect. Once unpacked you will see a directory hierarchy something like what is shown below: Where is the Data Located? Download gerbv — a Gerber RSX viewer for free. Free Gerber Viewer.
Select the desired OS to begin the download. This compact self-contained viewer allows you to view standard X format Gerber plotting documents. Short and misplld from my mobile Factory - the worlds smallest factory. I've used 'gerbv' from the begining.
I use Camtastic not sure if it's still available and GerberLogix, both free for non-commercial. It includes a complete toolset for clinical reporting of PACS studies. Radiologists can conveniently send CDs to referring physicians and other specialists for consultation. Gerberlogix can viewrr layers up and down, and I like that it can measure center to center for checking hole locations.
I used VewMate in the past, but they kept annoying me with forced updated and ads, so I switched to gerbv. Works fine for what I use. Primarily Intel Chipset Products.
