I'm a newbie in PCB design, I'm using PCB Editor 16.3 and I don't know what's the best way to organize mounting holes and mechanical parts:
- Put them in the orcad schematic so they are considered as components with a complete footprint.
- Leave them out of the schematic (so they are not included in the netlist). In this way I can change them without change the schematic but I don't know how to put parts that are not included in the schematic.
What are advantages and disadvantages of both solutions?
You need to make the mechanical parts and its information as a part of the schematic. As part of few good practices in PCB design ,it is considered to keep the schematic and board file in sync always.
1. If you have a footprint for the mechanical part, then simply place this part in Orcad schematic and add the property CLASS=MECHANICAL and it will be included in the netlist. (Make sure that Class=Yes is present in the component definition section of the allegro.cfg file).
2.To include all the mechanical part information in schematic, I found a detailed solution in the user guide "Including mechanical parts and assemblies in standard CIS BOM" in OrCAD CIS User Guide 17.4-2019
Below links helped me understand the process better -
