Delete iconto remove objects. With our grid presets defined, right-click on the Grid iconand select your METRICgrid. Now, from the left-hand toolbar, click on the Line tooland draw a 2 mm x 8mm rectangle about the origin as such (use the grid to assist): NOTE: You may have a black or white (as shown here) background.Make sure your rectangle is grey. This signifies you’re drawing on the correct layer (the 21 tPlacelayer to be specific, as designated in the top left corner). If you aren’t in the correct layer, click the drop-down menu and select the 21 tPlacelayer. Press escape to exit the line tool. Just to check, right-click on the top rectangle line, and select Properties. Check to make sure your values correspond (in mm): From = -4 & 1, To = 4 & 1, Layer = 21 tPlace.Select the Pad icon, click Round (to the right of the Grid icon), and place one pad to the left of the rectangle and another to the right as such:

IME 156 Eagle V 9.1 Tutorial 1/7/2019 15 As we want the pads to be 12.5 mm apart, have appropriate dimensions, AND correspond with the symbol’s pins, right-click on the left pad, then select Properties. We want the left pad to connect with the left pin in our symbol, so enter Name = 1. Fill in the remaining properties as such: Position = -6.25 & 0, Diameter = 1.7, Drill = 0.8NOTE: When dimensioning pads for your project, don’t make the Drill size exactly the same as the component’s pin size. Be sure to apply a spacing clearance so the leads fit through the drilled holes (any excess space will be filled with solder).For the sake of this tutorial, it doesn’t matter if Thermalsor Stopare checked. Select OKto apply these properties. We want the right pad to connect with the right pin in our symbol. Right-click on it and select Properties. Enter Name = 2, Position = 6.25 & 0, Diameter = 1.7, Drill = 0.8. Select OK.

IME 156 Eagle V 9.1 Tutorial 1/7/2019 16 Your resistor footprint should look like this:We’re almost finished creating the footprint. The final thing is to include the part name so it’s displayed on our circuit board! From the left-hand toolbar, select the Text tool. Type >NAMEexactly as shown below. Click OK. Before clicking anywhere, select the layers drop-down menu and click on the 25 tNameslayer.

It’s not there, because for the sake of this tutorial, we don’t care about this information when designing our board. Values (defined by you, in Ohms) will only be present in our schematic, because our symbolincludes the text “>VALUE”. Still in some circumstances, this piece of information may be required, so it never hurts to add it if you’re unsure! This will make more sense when we import the components to the schematic and board.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
