Additionally, Altium Designer Layout supports a wide range of file formats, making it easy to import and export designs from other EDA tools. This means that designers can work with a variety of design files, regardless of the software used to create them.
Overall, Altium Designer Layout is a powerful and versatile tool that provides designers with everything they need to create high-quality PCB layouts. Its user-friendly interface, real-time feedback, and support for multiple file formats make it a popular choice among electronic designers.
Creating a New Layout
Setting Up the Workspace
Before starting a new layout in Altium Designer, it is essential to set up the workspace correctly. The workspace includes the design files, libraries, and the user interface. To create a new layout, click on File > New > PCB. This action will open a new PCB document.
Defining the Board Shape
The next step is to define the board shape. To do this, click on Design > Board Shape > Define from the menu. The board shape can be defined using a pre-defined shape or by drawing a custom shape. Altium Designer offers a wide range of pre-defined board shapes, such as rectangular, circular, or polygonal shapes.
Placing Components
After defining the board shape, the next step is to place the components on the board. To place a component, click on Place > Component > Place Component from the menu. Altium Designer provides a wide range of components, including resistors, capacitors, ICs, and more. The components can be placed manually or automatically using the Auto-Placer tool.
Routing Traces
Once the components are placed, the next step is to route the traces. To route the traces, click on Route > Interactive Routing from the menu. Altium Designer provides a range of routing options, such as manual routing, auto-routing, and interactive routing. The interactive routing tool allows the user to route traces manually while providing real-time feedback on the design rules.
Adding Copper Pour
Finally, adding a copper pour to the board can help improve the performance of the circuit by reducing noise and improving signal integrity. To add a copper pour, click on Place > Polygon Pour from the menu. The copper pour can be defined using a pre-defined shape or by drawing a custom shape. Altium Designer provides a range of options to customize the copper pour, such as the net association, clearance, and fill style.
Overall, creating a new layout in Altium Designer involves setting up the workspace, defining the board shape, placing components, routing traces, and adding a copper pour. By following these steps, the user can create a high-quality PCB design that meets the design requirements.
Advanced Techniques
Multi-Board Design
Altium Designer Layout allows for multi-board design, which is the process of designing and connecting multiple printed circuit boards (PCBs) together to form a larger system. This technique is useful for complex electronic systems that cannot be accommodated on a single board. Multi-board design allows for better organization, easier maintenance, and improved performance.
To create a multi-board design in Altium Designer Layout, start by creating the individual PCB designs. Then, use the Multi-Board Assembly feature to define the connections between the boards. This feature allows for easy visualization of the connections and ensures that the design is properly connected.
High-Speed Design
High-speed design is a technique used to design PCBs that operate at high frequencies. This technique is important for applications such as telecommunications, networking, and data processing, where high-speed data transfer is critical.
Altium Designer Layout provides several tools to assist with high-speed design, including differential pair routing, length matching, and impedance control. These tools help to ensure that the design meets the required signal integrity and performance specifications.
Design Rule Checking
Design Rule Checking (DRC) is a process used to ensure that the PCB design meets the required specifications and standards. DRC checks for errors and inconsistencies in the design, such as overlapping traces, incorrect clearances, and incorrect drill sizes.
Altium Designer Layout provides a comprehensive set of DRC rules, which can be customized to meet specific design requirements. The DRC feature also allows for easy visualization of design errors and provides suggestions for correcting them.
Overall, Altium Designer Layout provides a powerful set of tools and features for advanced PCB design techniques. By utilizing multi-board design, high-speed design, and design rule checking, designers can create high-performance electronic systems that meet the most demanding specifications.
Exporting and Manufacturing
Generating Gerber Files
One of the most important steps in manufacturing a PCB is generating Gerber files. These files contain all the information required by the fabricator to manufacture your PCB. In Altium Designer, you can easily generate Gerber files by going to File > Fabrication Outputs > Gerber Files. Here, you can select the layers you want to include in the Gerber files, as well as the format and naming convention.
Creating a Bill of Materials
A bill of materials (BOM) is a list of all the components required to manufacture your PCB. In Altium Designer, you can create a BOM by going to the schematic and selecting Design > Make BOM. This will generate a BOM report that includes all the components in your design, along with their quantities and reference designators. You can customize the BOM report to include additional information, such as manufacturer part numbers and supplier information.
Collaborating with Fabricators
Collaborating with fabricators is an essential part of the manufacturing process. Altium Designer makes it easy to collaborate with fabricators by providing tools for generating Gerber files and BOMs, as well as tools for communicating with fabricators. For example, you can use the Altium Vault to share design files and collaborate with fabricators in real-time. You can also use the AltiumLive community to find fabricators and other resources for PCB manufacturing.
In conclusion, Altium Designer provides a comprehensive set of tools for exporting and manufacturing PCBs. With the ability to generate Gerber files, create BOMs, and collaborate with fabricators, Altium Designer makes it easy to take your design from concept to reality.
