why use eagle pcb
Why use Eagle PCB?

This is a cad package which is available as a freeware version (Eagle lite). Although it may look intimidating at first glance, can be used to produce quality printed circuit boards from circuit schematic diagrams.

It is an ideal tool to use for NCET Unit Standards 18242 and 18243.

The website from which this software can be downloaded (Windows and Linux versions are available) is www.cadsoft.de

how to use this presentation
How to use this presentation?

It would be useful to have access to two adjacent computers. Install and run Eagle on one and this presentation on the other. .

Alternatively, print the pages of this presentation and work through them with Eagle running on your PC. .

eagle title screen
Eagle Title Screen

This is the control panel screen which should appear when the programme opens.

eagle control panel

Directory tree. . .

To begin with only focus upon the LIBRARIES and PROJECTS directories

Eagle Control Panel
eagle pcb libraries
Eagle PCB Libraries

Click hereto display the LIBRARIES

libraries

These folders contain the data used to generate the symbols for the diagrams. They contain schematic pinout data for individual components and package layout diagrams used on the pcb layout

These buttons allow you to select and de-select files.

This file type contains schematic pinout data

This file type contains standard package layout diagrams used on the pcb layout.

File content descriptions

libraries schematic

Click on a schematic file

Symbol used in schematic diagrams

Lists of types sizes and shapes!

Libraries - Schematic

eagle pcb projects
Eagle PCB Projects

Click here to display the PROJECTS

projects

The Projects folders are where you place your work.

When creating a design there are two main types of file which are generated by the programme

.sch (Circuit schematic designs) and .brd (pcb layout boards)

Projects
schematics
Schematics

The schematic window allows the design of circuits like this flip-flop using standard component symbols

From this point the pcb can be created on the “board” screen

boards
Boards

This is a board produced from the previous schematic. . .

The software automatically generated the symbols and pathways from the schematic.

All positioning, track widths and pad sizes can be changed by the user.

pcb templates from boards

Text placed on the “bottom layer” is automatically reversed for printing

PCB templates from boards

The colour scheme can be customised and layers removed so that the track layer can be printed directly onto a transparency to produce a master for photo-etching
