Protel DXP PCB Layout Glenn Mercier 12/16/2005 PCB Layout Software There are many PCB Layout software packages available. For this tutorial, I will be using Protel DXP. „ Protel DXP 2004 „ Orcad Layout „ Eagle Layout Editor „ Express PCB „ PADS Introducing Protel DXP 2004 Reasons for Choosing Protel DXP „ Abundance of learning luides http://www.altium.com/Community/ Support/LearningGuides/ „ Large footprint library included „ Extensive design rule checking (DRC) „ Integrity testing „ Integrated software package „ Free Trial Available Main Screen Create new PCB Project Save the PCB Project File The project was created (*.PrjPCB), but needs to be saved, right click and save the project Create New Schematic „ Now we need to add files to the project. The beginning step is to add a Schematic Document. This is where the schematic drawings we are all familiar with will go. Right click and save the schematic document as before. Organization „ Your screen should now look like this. Notice the branching. The PIC schematic document is located in the project tutorial. Libraries „ There are three forms of libraries Schematic Library- This library contains schematic drawings that we are familiar with from ORCAD „ PCB/Footprint Library- This library contains the actual dimensions and pads for placing the component on the board. „ Integrated Library- Most manufacturers libraries are integrated, containing both Schematic and PCB libraries. „ Adding Libraries „ From the design menu, click Add/Remove libraries. Adding Libraries (Cont.) Adding Libraries (Cont.) „ Since most of us are using Microchip PIC microcontrollers, add the Microchip library Adding Libraries (Cont.) „ Each manufacturer usually categorizes their parts for easy selection. Choose the PIC18 Adding Libraries (Cont.) „ Add the highlighted libraries to the project. These two files are not in a folder, but in the root ‘Library’ folder Adding Libraries (Cont.) „ From the Library folder, go to the PCB folder, this folder contains PCB footprint libraries. Adding Libraries (Cont.) „ From the PCB folder, add Chip Capacitor „ Chip Resistor „ Crystal Oscillator „ Resistor- Axial „ Adding Libraries (Cont.) „ You should now have the following libraries installed. Note the top three libraries here are integrated libraries, and the bottom four libraries are PCB libraries Checkpoint „ If you expand the libraries folder, you should see the following. Now that we have added our libraries, we are ready to begin the schematic layout. Schematic Layout „ Double Click on your schematic document from the left navigator menu, and you should see a blank screen on the right Schematic Layout- Placing Parts „ From the ‘Place’ menu, click Part.
