What is Eagle?
EAGLE (Easily Applicable Graphical Layout Editor) is a flexible and expandable EDA schematic capture, PCB layout, autorouter and CAM program. EAGLE is popular among hobbyists because of its freeware license and rich availability of component libraries on the web.
Download and Install
There are installers for Mac, Linux and Windows. Choose the appropriate one for your operating environment and install it. Autodesk offers a 'Personal Learning License' for individuals working on non commercial projects.
EAGLE, Electronics design
Fusion + Eagle Intergration :
Eagle WorkFlow :
Opening Eagle . Create a New Project and Create a new schematic
Schematic ("Connection Plan/Drawing ")
Open Library Manager
Make sure fab.lbr is added and "in use"
Use the "ADD" tool to add components
Notice the Schematic Represenation and the footprint indicated
Adding the VCC and GND Symbols
Using the "Route Tool"
After adding the AVR ISP we use the "NAME" tool to rename the "NET" to the desired names
The Pop-Up for the naming tool
The correct dialog box that opens up after the connection
Placing Labels on the NET's helps in design and debugging.
Completing the Schematic
Using the SCR to BRD button to create the actual PCB
First instance of the Board Environment
Standard way that components are arranged
Select the "MOVE" tool to move the components and/or group of components
THE FIRST PLACEMENT OF THE COMPONENT SHOULD ALWAYS BE THE IC .( Simplifies a lot of things afterwards )
Select the "RatsNest" tool to optimise the airwires . This tool optimises the lenght of the airwire making shorter pcb traces
Notice the slight change of airwires
Optimised Placement of Components
Select the "Route Tool"
Select the width to "16 mil " ( 1 mil = A thousandth of an inch )
Shown here is the two traces are two traces that are two close to be used . In this case use the "RIPUP" tool
This converts the trace to airwire
Sometimes you can also change the grid size of the board to allow for finer control
There is no option but to use a few "Jumpers on the board " . So i tried adding just adding pads to the board.
Eagle doesn't allow me to do that there needs to be a component in the schematic to represent
So i first added 3 random resistors in the schematic
The resistors appear in the board environment
We first place the components at the right place . but Eagle does not allow me to connect to that pad .
I switch back to the schematic to reconnect this resistor to the right pin
Now we connect the resistors
Completed Layout of the board
I go to layer settings to export the image for production
List of available layers in Eagle .
For generation of "traces" select TOP and DIMENSION
Dialog box shows here the options
IMPORTANT THINGS TO BE KEPT IN MIND
DPI : 1000 and MONOCHROME to be selected
To export the cutout file select only the "DIMENSION " layer of the Board .
Voila file ready to be milled
