There are many factors to consider when creating files for PCB fabrication and manufacturing. The most important thing to keep in mind is to make sure all the files are accurate and up to date. This includes the gerber files, bill of materials, and any other documentation. Keeping everything organized and in one place will make the process go much smoother and help avoid any potential problems.
1. Files for PCB Fabrication and Manufacturing
When it comes to prototyping and small-scale production of printed circuit boards (PCBs), there are a few different file formats that can be used to send instructions to the manufacturer. The most common file formats are Gerber, Excellon, and PDF. In this blog post, we’ll take a closer look at each of these file formats and how they’re used in PCB fabrication and manufacturing.
Gerber files are the most common type of file used for PCB fabrication. They’re typically generated by PCB design software and contain all of the information needed to produce the circuit board. Gerber files can be used to produce both single- and double-sided boards.
Excellon files are used to control the drilling of through-hole vias. They contain information about the location and size of each via hole. Excellon files are typically generated by PCB design software and sent to the manufacturer along with the Gerber files.
PDF files can be used to generate both Gerber and Excellon files. They can also be used to generate a production drawing of the PCB. PDF files are typically generated by PCB design software and sent to the manufacturer along with the Gerber and Excellon files.
When sending files to a manufacturer for PCB fabrication and manufacturing, it’s important to make sure that all of the necessary files are included. Gerber, Excellon, and PDF files are the most common types of files used in PCB fabrication and manufacturing.
2. The Importance of Gerber Files
As a Printed Circuit Board (PCB) designer, you know that the success of your design hinges on the quality of your Gerber files. But what exactly are Gerber files, and why are they so important?
In this blog post, we’ll take a closer look at Gerber files, what they are used for, and why they are so critical to the success of your PCB design.
What are Gerber files?
Gerber files are the standard file format for PCB manufacturing. They contain all the information necessary to produce your PCB, including the board outline, layer stackup, component placement, and routing.
Gerber files are generated by your PCB design software and are typically exported as .zip files.
Why are Gerber files so important?
Gerber files are so important because they are the only files that your PCB manufacturer will use to produce your board. This means that if your Gerber files are inaccurate, your PCB will likely be inaccurate as well.
This is why it’s critical to make sure that your Gerber files are accurate and up-to-date before sending them to your manufacturer.
How to ensure your Gerber files are accurate
There are a few things you can do to ensure that your Gerber files are accurate:
1. Use reputable PCB design software: Be sure to use PCB design software that is known for generating accurate Gerber files.
2. Check your files before exporting: Before exporting your Gerber files, be sure to check them for any errors. Most PCB design software will have a built-in Gerber viewer that you can use for this purpose.
3. Use a Gerber file checker: There are a number of Gerber file checkers available online that can help you check for errors in your files.
4. Send your files to a trusted manufacturer: Once you’ve checked your Gerber files for accuracy, send them to a trusted and experienced PCB manufacturer. At JCLPCB, we offer a free Gerber file check service to help ensure that your files are accurate before we begin manufacturing your board.

3. How to Generate Gerber Files
Assemble your PCB design in your preferred PCB design software. Most PCB design software will generate Gerber files for you. If your software does not, you can use a free online converter like GerbTool.
To generate Gerber files, you will need to export your design in the following formats:
– Board outline: This is the outline of your PCB. It is typically exported as a DXF or PDF file.
– Copper layers: These are the layers that will be etched onto your PCB. They are typically exported as GERBER files.
– Drill files: These are the files that tell the manufacturer where to drill the holes on your PCB. They are typically exported as EXCELLON files.
– Silkscreen: This is the layer that contains the text and graphics that will be printed on your PCB. It is typically exported as a GERBER file.
– Soldermask: This is the layer that defines the areas where solder will be applied to your PCB. It is typically exported as a GERBER file.
– Peel-off mask: This is a layer that is used to protect the solder mask during the soldering process. It is typically exported as a GERBER file.
After you have exported all of the necessary files, you will need to zip them up into a single file. This will make it easier to send them to your manufacturer or fabricator.
4. The Importance of Drill Files
As a Printed Circuit Board (PCB) designer, you need to have an understanding of the different types of files used in the PCB design and manufacturing process. One of the most important types of files is the drill file.
A drill file is a file that contains all the information needed to produce the holes in a PCB. The drill file is typically generated by the PCB design software and sent to the PCB manufacturer along with the other files needed to produce the board.
The drill file is important because it tells the manufacturer how to drill the holes in the PCB. The manufacturer will use this information to create the tooling needed to drill the holes. If the drill file is not correct, the holes may not be drilled in the correct locations or the wrong size.
There are two common formats for drill files: Gerber and Excellon. Gerber is the most common format and is used by most PCB design software. Excellon is a more specialized format that is often used for CNC drilling machines.
It is important to check with your PCB manufacturer to see which format they prefer. Some manufacturers can work with either format, while others may only work with one or the other.
Once the PCB design is complete and the drill file is generated, it is important to check it for accuracy. This can be done by opening the file in a text editor and looking at the coordinates of the holes. The coordinates should match the locations of the holes on the PCB layout.
If the file looks correct, it can be sent to the manufacturer. If there are any errors, they can be corrected and the file resubmitted.
The drill file is an important part of the PCB design and manufacturing process. It is important to understand the different formats and how to check the file for accuracy. By doing so, you can ensure that the holes in your PCB are drilled in the correct locations and the right size.

Make sure to check with your manufacturer to see which file format they prefer.
2. The second thing you need to do is make sure your design includes all the necessary drill sizes. This seems like a no-brainer, but it’s easy to forget to include a few small sizes here and there. Again, check with your manufacturer to see what sizes they need.
3. Once you’ve double-checked your design and file format, you can export the file from your design software. Again, make sure to use the correct file format for your manufacturer.
4. The next step is to check the file for errors. This is a critical step, as even a small error can cause big problems during the fabrication process. There are many different ways to check for errors, so consult your design software documentation or your manufacturer for more information.
5. The last step is to send the file to your manufacturer. Once you’ve checked the file for errors, you’re ready to send it off. Make sure to include any special instructions for your manufacturer, such as which side of the board should be drilled first.
6. The Importance of NC Drill Files
If you are planning on making a Printed Circuit Board (PCB), you will need to have the proper files in order for the board to be fabricated and manufactured correctly. One of the most important files that you will need is called an NC Drill File. In this blog, we will discuss what an NC Drill File is and why it is so important for your PCB project.
An NC Drill File is a machine-readable file that tells the PCB fabricator or manufacturer how to drill the holes on your PCB. This file is typically generated by your PCB design software and will contain information on the size, shape, and location of each hole that needs to be drilled. Without this file, it would be very difficult for the fabricator or manufacturer to produce your PCB correctly.
There are a few different types of NC Drill Files, but the most common is the Gerber NC Drill File. This type of file is typically used by PCB fabricators and is very easy to read and understand. The other type of NC Drill File is the Excellon NC Drill File. This type of file is typically used by PCB manufacturers and is a bit more difficult to read and understand. However, both types of files are equally important and will need to be provided to the fabricator or manufacturer in order for your PCB to be made correctly.
As you can see, the NC Drill File is a very important file that is needed for your PCB project. Without this file, it would be very difficult for the fabricator or manufacturer to produce your PCB correctly. If you are planning on making a PCB, be sure to generate an NC Drill File and provide it to the fabricator or manufacturer.
7. How to Generate NC Drill Files
When it comes to PCB fabrication and manufacturing, one of the most important things to get right are the NC drill files. These files provide the instructions to the CNC machine that will be used to drill the holes in your PCB. Getting these files correct is essential to ensuring that your PCB is manufactured correctly.
There are a few different ways to generate NC drill files, and the method you choose will depend on the software you are using and your personal preferences. In this article, we will go over some of the most common methods for generating NC drill files.
1. The first method is to use a PCB design program that has built-in support for generating NC drill files. Programs like Altium Designer and Eagle have this functionality, and it is usually pretty straightforward to use. Simply select the layer(s) that you want to include in the NC drill file and then export the file in the appropriate format.
2. Another common method is to use a separate program that is specifically designed for generating NC drill files. There are a number of these programs available, and they typically have a pretty simple interface. You simply select the Gerber files that you want to include and then export the file in the appropriate format.
3. The last method is to use a generic CAD program like AutoCAD or Solidworks. These programs do not have specific support for generating NC drill files, but you can still use them for this purpose. The process is a bit more involved, but it is still relatively straightforward. You will need to create a separate layer for each drill size that you want to include in the file. Then, you will need to create a series of circles on each layer that represent the drill holes. Once you have all of the holes created, you can then export the file in the appropriate format.
Which method you choose to use is ultimately up to you. If you are using a PCB design program that has built-in support for generating NC drill files, then that is probably the easiest way to go. If you are using a generic CAD program, then the process is a bit more involved but it is still possible to do. Whichever method you choose, just make sure that
8. The Importance of CAM Files
CAM files are the instructions that tell the computer what to do when fabricating a printed circuit board. They are also known as “Gerber files”, after the company that originally developed the software that creates them.
The CAM files are generated by the design software, and they contain all of the necessary information to produce the PCB. This includes the dimensions of the board, the location of the holes, the width of the traces, and the surface finish.
The CAM files are sent to the manufacturer, who uses them to produce the PCB. The manufacturer will also use the CAM files to check the design for errors.
It is important to have accurate CAM files, as they are the instructions that the manufacturer will use to produce the PCB. If there are any errors in the CAM files, it is likely that the PCB will not be fabricated correctly.
In order to ensure that the CAM files are accurate, it is important to check them carefully before sending them to the manufacturer. The design software will usually have a built-in CAM viewer that can be used to check the files.
It is also a good idea to send the CAM files to a few different manufacturers for quotes. This way, you can compare the prices and turnaround times, and choose the best option for your project.
The bottom line is that CAM files are essential for the fabrication of printed circuit boards. They are the instructions that tell the manufacturer how to produce the PCB, and they need to be accurate in order to avoid errors.
9. How to Generate CAM Files
If you’ve ever sent a PCB design to a manufacturer only to have it come back full of errors, you know how frustrating it can be. One way to avoid this is to generate a CAM (Computer Aided Manufacturing) file along with your design files. In this blog, we’ll show you how to generate a CAM file and what to include in it to ensure your design is fabricated correctly.
To generate a CAM file, you’ll need a PCB design software that supports CAM output. We recommend using Altium Designer for this. Once you have your design ready in Altium, go to File » Fabrication Outputs » CAM Documents.
This will open the CAM Wizard. The first thing you’ll need to do is select the layers you want to include in your CAM file. For a standard 2-layer PCB, you’ll want to select at least the Top and Bottom layers. You can also include the Inner layers if your design has them.
Next, you’ll need to select the output format for your CAM file. The most common format is Gerber, but you can also use DXF or DWG. If you’re not sure which format to use, check with your manufacturer.
Once you’ve selected your layers and output format, click Next. On the next page of the wizard, you’ll be able to specify the details of your design, such as the board outline, hole sizes, and so on. You can also include a legend or other information on this page.
When you’re finished, click Finish to generate your CAM file. You can then save it to your computer and send it to your manufacturer.
By following these steps, you can be sure that your design will be fabricated correctly. If you have any questions about generating a CAM file, please contact us and we’ll be happy to help.
