The data contained in this specification is intended to supplement ANSI/IPC-D-350, specifically in the area of describing printed wiring board related drawings in digital form. It is intended that the basic record formats described in D-350 also apply to the record format described in this supplement. These formats may be used for transfer of drawings between printed wiring board designers, manufacturers and customers.

The intent of this specification is to convey additional requirements, guidelines and examples necessary to provide the data structures and concepts for drawing description in digital form. This supplement pertains to four basic types of drawings:

Printed board schematic diagram (see Figure 1-1)

Printed board master drawing (see Figure 1-2)

Printed board assembly drawing (see Figure 1-3)

Miscellaneous part drawings (see Figure 1-4)
