In this video I’m showing you the back end of how I’m using Altium’s Bill of Materials Manager (Altium Develop) to deal with real supply chain friction on a production-grade PCB BOM—specifically the NVIDIA Jetson AGX Orin carrier board. This isn’t the “the part is obsolete” story. The part might be in abundance, but there are better recommended parts (or the manufacturer part number quietly changed), and if you don’t catch that early your assembly process gets wrecked. I walk through the exact workflow I use: clean up missing or weak component descriptions (because if you don’t have a good description, then what are you doing?), then use the supply chain dashboard to surface availability and pricing risk across the entire BOM. I show how I’ll jump between Octopart and Digi-Key to hunt down a likely MPN update, confirm the electrical intent using the description (package, value, tolerance, etc.), and then patch the BOM so the tool can actually verify sourcing again. The big takeaway: the component description is the shorthand datasheet, and it’s the only way you can confidently compare alternates when part numbers break. And the supply chain view makes it painfully obvious: if it’s not available, your board’s not getting assembled—period.
