IPC Parts List A parts list is a tabulation of parts and materials used in the construction of a printed board assembly. All end item identifiable parts and materials shall be identified in the parts list or on the field of the drawing. Excluded are those materials used in the manufacturing process, but may include reference information; i.e., specifications pertinent to the manufacture of the assembly and reference to the schematic/logic diagram.

IPC Parts List All mechanical parts appearing on the assembly pictorial shall be assigned an item number which shall match the item number assigned on the parts list. Electrical components, such as capacitors, resistors, fuses, IC's, transistors, etc., shall be assigned reference designators, (Ex. C5, CR2, F1, R15, U2, etc.). Assignment of electrical reference designators shall be the same as (match) those assignments given to the same components on the Logic/schematic diagram.

IPC Parts List It is advisable to group like items; e.g., resistors, capacitors, IC's, etc., in some sort of ascending or numerical order. The parts list may be handwritten, manually typed on to a standard format, or computer generated.
