Meaning
A structured system of naming conventions for parts and assemblies ensures clear and unambiguous communication across design, purchasing, and manufacturing departments. Effective nomenclature reduces errors in component procurement and prevents confusion on the assembly line. It uses logical codes that embed key parameters like resistor tolerances or package sizes directly into the part identifier.
This consistency is essential when multiple revisions of a board must be managed in a shared inventory system.
Part Numbering
Structuring these codes requires defining a fixed format that scales with the growing number of components. The chosen nomenclature assigns specific prefixes to component categories, such as RES for resistors and CAP for capacitors, followed by value and package sub-codes. When a new part is created in the electronic design database, its part number must strictly follow these rules to ensure it is grouped correctly in the bill of materials.
This organization helps automated assembly equipment locate the correct reels on the factory floor.
Document Control
Version tracking relies on standardized suffixes to indicate minor and major design changes. The document control team reviews these changes to ensure they are documented in engineering change orders. This prevents the release of outdated layouts to the manufacturing floor.
Supply Chain
Procurement teams use these part numbers. They order parts from distributors.
