How Open Pcb File

A PCB Gerber file for each section of your electronic circuit design is what you need if you want to create a PCB. In order to ensure delivery time and reliability of end products, PCB design engineers should learn how to generate PCB Gerber files on their own. PCB Gerber files generally contains design data of signal layer, soldermask layer and silkscreen layer.


Nowadays, there are three versions of Gerber formats available:

How to open PCB files If you cannot open the PCB file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports PCB among those that are installed on your device. A very simple way to solve this problem is to find and download the appropriate application.


  1. The below scan tools will open in a non-mobile friendly page format and ONLY FUNCTION IN INTERNET EXPLORER. If you wish to use these tools, please open the page IN ADMINISTRATOR MODE using Internet Explorer. To open Internet Explorer in admim mode, right-click on the IE shortcut icon or IE link and select 'Run As Administrator'.

Powerpoint

• Gerber X2 - the newest Gerber format with stackup data and attributes contained.

• RS-274-X - an expanded version of Gerber format and it has been widely applied.

• RS-274-D - the oldest version of Gerber format which is being gradually replaced by RS-274-X


Different PCB design software feature different operation steps of PCB Gerber files generation. In the following part of this article, We will show you how to generate PCB Gerber file from Cadence Allegro in details.


Open your PCB layout in Cadence Allegro:


1. First, manually add artwork layers, and then click Manufacture>>Artwork.



2.Click General parameters, setting as shown below:




3.Then click Film Control,add artwork layers, add a board outline by right-clicking on the TOP folder and picking Add Manual.



4. Determine a film name, OUTLINE for example and click OK button.




5. In the Subclass Selection window, expand BOARD GEOMETRY and tick OUTLINE. Then, click OK button

6. Back to Artwork Control Form window, tick OUTLINE if it has stayed in the area of Available films.




7. Use the same method to add other layers, Assembly layer is similar to the picture below



All the signal layers are set similar to the picture below:



Drill layer is set similar to the picture below:



Silkscreen layers are set similar to the picture below:

Paste mask layers are set similar to the picture below:



Then setting and output the drilling file


1. Add the drilling table


Open the Drill layer through the Views list of the Visibility option on the right side of the screen, and select both the PIN and Via options in the Visibility option, as shown below:



Then click Manufacture>>NC>>Drill Legend, as shown below:




The drilling table parameters are setting as shown below:



Open Pcb File Ppt

Click the OK button, a drilling table appears, placed in the appropriate place on the board.


2.Output the drilling file




How

The parameters are setting as shown below:


How Open Pcb File



Output drilling files, as shown below, it is best to click the dirll button to generate .Dril files which means drilling files




With these steps finished, you need to re-confirm whether each parameter is set correctly, if there is no problem,press Select all button with all the layers output. Then, PCB Gerber files will be generated when Create Artwork button is clicked.
