What is the difference between an engineering BOM and a manufacturing BOM?

A manufacturing BOM contains all the parts and assemblies required to build a complete and shippable product. It typically provides information on how parts are related to each other and how the finished product is structured. An engineering BOM, on the other hand, is organized according to MCAD/EDA tools and represents the physical product being “engineered,” not the packaging or manufacturing consumables.
