Introduction to PCB Design and Eagle Software
Printed Circuit Board (PCB) design is a crucial aspect of electronics manufacturing. It involves the creation of the layout and design of the circuit board that connects and supports various electronic components. PCB design requires specialized software tools to ensure accuracy, efficiency, and adherence to industry standards. One of the most popular PCB design software tools is Eagle, developed by Autodesk.
Eagle, which stands for “Easily Applicable Graphical Layout Editor,” is a powerful and user-friendly PCB design software. It offers a comprehensive set of features and tools that enable designers to create high-quality PCB layouts quickly and efficiently. Eagle’s popularity among PCB design companies can be attributed to its ease of use, extensive component libraries, and robust design capabilities.
In this article, we will explore the world of PCB design companies that use Eagle software. We will discuss the benefits of using Eagle for PCB design, its key features, and how it streamlines the design process. Additionally, we will provide a list of notable PCB design companies that rely on Eagle for their projects.
The Benefits of Using Eagle for PCB Design
User-Friendly Interface and Intuitive Workflow
One of the primary reasons why PCB design companies choose Eagle is its user-friendly interface and intuitive workflow. Eagle provides a clean and organized workspace that allows designers to navigate through the design process seamlessly. The software’s logical layout and well-structured menus make it easy for both beginners and experienced designers to create PCB layouts efficiently.
Extensive Component Libraries
Eagle comes with an extensive collection of component libraries that include a wide range of electronic components, such as resistors, capacitors, integrated circuits, and connectors. These libraries are regularly updated, ensuring that designers have access to the latest component information and footprints. The availability of a vast component library saves designers significant time and effort in creating custom components from scratch.
Schematic Capture and Board Layout Integration
Eagle seamlessly integrates schematic capture and board layout functionalities, enabling designers to create a complete PCB design within a single software environment. The schematic capture feature allows designers to create and edit electronic schematics, while the board layout feature enables them to place components and route traces on the PCB. The integration of these two aspects ensures consistency and accuracy throughout the design process.
Design Rule Checking (DRC) and Error Prevention
Eagle incorporates a powerful Design Rule Checking (DRC) feature that helps designers identify and resolve potential design issues before sending the PCB for manufacturing. DRC checks the PCB layout against a set of predefined design rules, such as minimum trace widths, clearances, and hole sizes. By detecting and highlighting design rule violations, Eagle prevents costly mistakes and ensures that the PCB design meets the required specifications.
Customization and Scripting Capabilities
Eagle provides a high level of customization and scripting capabilities, allowing designers to automate repetitive tasks and extend the software’s functionality. Users can create custom scripts using the Eagle Command Language (ECL) to perform specific actions, such as generating bill of materials (BOM), exporting design files in various formats, or applying custom design rules. This flexibility enables PCB design companies to streamline their workflows and adapt Eagle to their specific requirements.

Eagle PCB Design Workflow
The typical workflow for designing a PCB using Eagle software involves several key steps:
-
Schematic Design: The first step is to create a schematic diagram that represents the electrical connections between the components. Eagle’s schematic editor allows designers to place components, draw wires, and define the logical connections of the circuit.
-
Component Placement: Once the schematic is complete, designers switch to the board layout view. Here, they place the physical components on the PCB, considering factors such as component size, orientation, and spacing.
-
Routing: After placing the components, designers route the traces between them to establish the electrical connections defined in the schematic. Eagle’s autorouter feature can automatically route traces based on predefined design rules, saving time and effort.
-
Design Rule Check: Before finalizing the PCB layout, designers run a Design Rule Check (DRC) to ensure that the design meets the specified manufacturing constraints. Eagle’s DRC feature identifies any violations and provides feedback for correcting them.
-
Export and Manufacturing: Once the PCB design is complete and error-free, designers export the necessary files, such as Gerber files and drill files, for manufacturing. These files are then sent to a PCB fabrication company for production.
By following this workflow and leveraging Eagle’s powerful features, PCB design companies can efficiently create high-quality PCB layouts that meet their clients’ requirements.
