This tutorial leads you through the steps necessary to make a simple two-sided PCB using EAGLE. This guide is operational: it shows in detail what you do and how to do it. Before you start the tutorial take 5 minutes to go through the Cadsoft EAGLE Guided tour, to get an overview. It will pay you to work through all of this guide, following the steps yourself, before attempting your first unguided PCB.
A short note about the EAGLE on-line help documentation. This is pretty good but based on the command-line interface to EAGLE. It is easier when learning to use the drag-and-drop GUI, which we follow in this tutorial.
This guide assumes that you are designing a two-sided PCB with plated-through holes (PTH), the normal case, and supported by the freeware version of EAGLE providing your board is no larger than 100mmX80mm. If you want to download the freeware EAGLE to your own PC this is easy. Look for the latest freeware version for your operating system & language (e.g. eagle-win-5.2.exe for windows XP and English).
EAGLE can also be used to design multi-layer and single-sided PCBs, non-PTH PCBs, etc. It can also be easily adapted to produce boards with coarser features, suitable for low quality optical processes and manual manufacture. See the EAGLE Configuration Guide for more details of use with different technologies after you have followed this guide. In order to design a PCB, you need to complete the following steps:
1. Create a schematic sheet & add components
2. Add nets to the schematic (connect components)
3. Check schematic (Electrical Rule Check or ERC)
4. Create a board outline
5. Position components on the board
6. Route tracks between the components
7. Check board (Design Rule Check or DRC)
8. Pour copper to fill empty spaces on the board
9. Perform Final Checks
