3.4 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.

3.4 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.
