<b>EE445L Library</b>
<p>
This library has been compiled by EE445L professors, TAs,
and students. It is meant as a service to students,
simplifying the design, manufacturing, and testing of PCBs associated with the
Cirqoid PCB milling machine in the College of Engineering <b>Makerspace</b>.
For more information about the PCB mill see <b>http://cirqoid.com/</b>.
There are a number of restrictions that we will need to follow to simplify the PCB construction.
<p>
<b>PCB size.</b> There are two standard sizes of the PCB material one can order from Cirqoid: 100 by 75 mm, and 100 by 160 mm. The smaller size allows you to design the PCB in the freeware version of Eagle. You can of course, set the board size to be less than 100 by 75 mm.
<p>
<b>Number of layers.</b> You can create single or double layer PCBs with the Cirqoid PCB mill.
<p>
<b>Drill sizes.</b> The Makerspace only has specific drill sizes. This library will restrict drill sizes to these four:
0.0157in=0.4mm,
0.0315in=0.8mm,
0.0433in=1.1mm, and
0.120in=3.0mm. You can only drill holes of a certain size, if you have a drill of that size. Second, the fewer drill sizes you use the faster it will be to manufacture the board.
<p>
<b>Placement of vias.</b> The Cirqoid PCB mill will not pour copper into vias which run from the top to bottom layers. Therefore you will need to place wire into the vias and solder on both sides. This means one must be careful where the vias are located (e.g., not under chips_ so you will have access to solder both layers.<p>
Use the <b>ADD</b> command in the Schematic Editor or Layout Editor
window to search for a certain device or package!
<p>
If you are going to create new parts, please do not add them to this library. This is because we routinely make updates to the this library, and if you add your part to this library, it will/may be lost when you install a newer version of the EE445L library.
