What is the preferred method for indicating components that aren't populated in OrCAD Capture 16.6? Do I just simply add text next to the schematic symbol that says "Do Not Populate", or is there something in the property editor that I can add or change so that the component shows that it shouldn't be populated when I generate the BOM?
I can manually make the changes to the bill of materials as well as the schematic, I was just wondering if there was some feature of OrCAD that could handle this for me.
I usually just put OPEN in the part value. When you run the BOM you will have all of the unpopulated part references listed under OPEN.
I have another customer that likes to have a dashed box put around the part with DNI insode the box. This maintains the part value on the schematic, but you can't tell it is a "Do Not Install" when you run the BOM.
In reply to TH Designs:
Ah. OK, thanks, Tom. Well, I made a few copies of the DSN file, labeled the components that aren't populated with DNP (Do Not Populate), and then made copies of the BOM and made the changes to the individual BOMs.
I was thinking that there might have been a more streamlined way to do this in OrCAD. If anybody has any more suggestions or methods for doing this, let me know.
In reply to David Yackman:
I use a slighty more cumbersome system but it supports certain MIL requirements I have had to comply with in the past.
I add a delta note (or flag note or whatever you want to call it) that states: INDICATED COMPONENTS NOT INSTALLED. I then place the delta note call-out next to each component not to be installed. I work with some engineers who want this flexibility in their designs and this seems to satisfy both the engineering and manufacturing sides of the various companies I have worked for. The down side is that you do have to manually remove the components from the BOM to start with. The up side is that it is just simple editing of the note text on the schematic and updating the BOM via am ECN.
In reply to BuddSw:
My KISS method:
Add a feild called note
In the "Note" feild place the text DNP.
Display the value only of the note feild
Add this feild to the BOM output.
Move part, the DNP follows the part. In a Hierachical drawing, you can populate or blank this feild out per occerance....
Typically I just enter N.U.T.A for the part value which means "Not Used This Assembly" When you generate the bom the N.U.T.A stands out pretty good.
