Your bill of materials lists every part you chose, but the biggest supply chain risk on your board is the one you never chose: the laminate, resin, and copper underneath it. In April 2026, circuit boards got as much as 40% more expensive in a single month while the BOMs on them never changed, and this video shows where that risk lives and how to find your own version of it.
Using Octopart's free BOM tool, we upload a spreadsheet, turn every line into a live part with stock, price, and lifecycle status, then dig into lead times, inventory history, stock alerts, and RoHS/REACH compliance to catch the parts that are quietly draining off the shelves. You'll also get the one question to ask your fab that no BOM tool can answer, and the one-second source check that would have caught a retracted 70% resin-supply claim that ran for months. Whether you're an engineer, buyer, or founder managing a BOM, this is the layer below your parts list that decides what your board actually costs.
