What is an engineering bill of materials (EBOM)? 

EBOM (Engineering bill of materials) A BOM organized according to CAD/EDA tool and engineers’ preferences and processes. The EBOM represents only the physical product being “engineered,” not the packaging or manufacturing consumables. It often includes items for a single engineering discipline only, summarizing or excluding items from other disciplines.

t originates in software used by the engineering department, such as computer-aided design or electronic design automation. The engineering bill of materials provides the components and directions to make a given product and includes things like raw materials, items, parts, subassemblies, interrelated data layers, as well as other factors, such as those that contribute to the cost of the product.

The engineering bill of materials focuses on parts as they exist in the design sense, and typically lists items from the engineering perspective, for example, on an assembly drawing. It does not include things like packaging, shipping containers and other components needed for a shippable product, or specify how parts should be grouped at each stage of production. Such items are instead typically included in the manufacturing bill of materials.
