Build Your Own PCB with EAGLE III - Turning the EAGLE Schematic into a PCB

  1. 1. Build Your Own PCB with EAGLE III – Turning the EAGLE Schematic into a PCB <ul><li>Source: CadSoft </li></ul>
  2. 2. Introduction <ul><li>Purpose </li></ul><ul><ul><li>To explain how to design a PCB from a schematic using EAGLE Board Editor. </li></ul></ul><ul><li>Outline </li></ul><ul><ul><li>EAGLE Layout Editor User Interface </li></ul></ul><ul><ul><li>Key steps for design a PCB from a schematic </li></ul></ul><ul><ul><li>Autorouter </li></ul></ul><ul><ul><li>Generating Gerber files </li></ul></ul><ul><li>Content </li></ul><ul><ul><li>15 pages </li></ul></ul>
  3. 3. Board Editor User Interface Title Bar Toolbar Menu Bar Parameter toolbar Command Line Command Toolbar Working Area Status Bar
  4. 4. Creating a Board for a Schematic <ul><li>To start laying out the PCB, you should open the schematic and click on the board-button. </li></ul>Board Area Board Editor Devices from the schematic Switch to Board
  5. 5. Placing Components <ul><li>Use “MOVE” command to drag the various components to the desired positions. </li></ul>Air wires Move Command
  6. 6. About Board Layers Bottom (Solder) side copper traces Bottom 16 Other copper layers (not support in Light Edition) 2-15 Top (component) side copper trances Top 1 Description Layer Name Layer Number Mirror Command
  7. 7. Manual Routing <ul><li>The ROUNTE command ( ) allows the airwires to be converted into tracks. </li></ul><ul><li>A click on the middle mouse button while a track is being laid allows a change of layer. </li></ul><ul><li>Clicking with the right mouse button changes the bend of the track. </li></ul>Top layer track Bottom layer track Via connecting tracks in different layers Airwire Track bend
  8. 8. Routing – Autorouter <ul><li>Start the Autorouter by clicking the AUTO icon ( ) in the command toolbar. </li></ul>
  9. 9. Autorouter Features <ul><li>SMDs are routed on both sides </li></ul><ul><li>The whole drawing area can be the routing area </li></ul><ul><li>The strategy is selected via control parameters </li></ul><ul><li>Simultaneous routing of various signal classes with various track widths and minimum clearances </li></ul><ul><li>Common data set (Design Rules) for the Design Rule Check and the Autorouter </li></ul><ul><li>Multilayer capability </li></ul><ul><li>Support of Blind and Buried vias </li></ul><ul><li>The preferred track direction can be set independently for each layer: horizontal and vertical, true 45/135 degrees </li></ul><ul><li>Ripup and retry for 100 % routing strategy </li></ul><ul><li>Optimization passes to reduce vias and smooth track paths </li></ul><ul><li>Prerouted tracks are not changed </li></ul>
  10. 10. The Autorouter Menu <ul><li>The Autorouter can't layout wires as arcs! </li></ul><ul><li>The Autorouter can't set micro vias! </li></ul><ul><li>The Autorouter can't set Blind and Buried vias if inner layers are defined as Supply layers! </li></ul>
  11. 11. Manually Routing Again <ul><li>RIPUP command ( ) is used to convert routed tracks into unrouted signals (airwires). </li></ul><ul><li>Then use ROUTE command to place track manually. </li></ul>Track before ripup Track after ripup
  12. 12. Design Rules Setting <ul><li>USE DRC command ( ) to open design rules setting window: </li></ul><ul><ul><li>File: Manage the Design Rules </li></ul></ul><ul><ul><li>Layers: Number of copper layers, structure of multilayer boards, kind and length of vias, thickness of copper and isolation layers </li></ul></ul><ul><ul><li>Clearance: Distances between objects in the signal layers representing signals that may be different or the same </li></ul></ul><ul><ul><li>Distance: Distances from the board edge and between holes </li></ul></ul><ul><ul><li>Sizes: Minimum track width and hole diameter, particularly for Micro and Blind vias </li></ul></ul><ul><ul><li>Restring: Width of the remaining ring at Pads and (Micro) vias and the diameter of Thermal and Annulus symbols in supply layers </li></ul></ul><ul><ul><li>Shapes: Shapes of Pads and SMDs </li></ul></ul><ul><ul><li>Supply: Thermal and insulation symbols in supply layers </li></ul></ul><ul><ul><li>Mask: Values for solder stop and solder cream masks </li></ul></ul>
