Steps for Making a Pcb
Procedure for creating a PCB:
OrCAD Capture:
First to create a PCB circuit, we start by opening OrCAD Capture ("File", "New" and click on "Design" or "Project.
Afterwards, we click the "Place Part" submenu and we add the important and necessary libraries. If necessary we place the parts and make correct connections (it is done by typing the name of the part we want in "Part" and choosing "Part Search" so that we can click on "Begin Search" and choose any library files that are necessary for our project).
Then we place the respected parts and link them depending on the schematic given.
Afterwards, we place "No Connect" for any unconnected pins.
It is recommended to click on "No Connect" for any useless pins (according to the circuit) in order to facilitate the schematic's design.
We have to be sure that all part have a unique "Part Reference" and if applicable, a "Value" so that the circuit will be error-free.
After the circuit is completed, we click on "DRC check" in order to prevent any errors that are present. And if there is any, we correct them before proceeding (to produce a DRC check, we should go into the project's main menu and select the DRC check button under the "Tool" menu).
Afterwards, we should add a footprint to all the necessary components by editing or modifying a component and adding a footprint in the "PCB Footprint" column (a footprint is basically the "blueprint" of the circuit, in other words, its unique combination will help choose the best possible parts in order to design a perfect circuit. To find the PCB Footprint for a specific part, the "Library Footprints" book is located in almost every CDST computer lab.
Annotating the design by making sure that "Update entire Design" and "Unconditional Reference Part" are checked.
Then we should create a "Netlist" (.MNL) file by going to the "Create Netlist" option, "Layout" sub-option and checking that "Combined property string:" has "{PCB Footprint}" also that
