PCB Manufacturing Documentation

It has always been important to produce accurate and comprehensive documentation for the maufacture and assembly for any design of PCB. It is often assumed that the fabricator or assembler knows what to do anyway so I'll be minimal with my paperwork. Sometimes this is true and mimimum documentation will suffice, however using the doumention tools at your disposal could prevent serious misunderstandings.

The IPC have produced a standard to help designers provide the necessary drawings and support documentation; namely IPC-D-325 this together with the tools provided by your EDA vendor should be enough for you avoid embarrassing misunderstandings.

Example: use the layer naming convention as IPC-D-325 Viz: Primary side is Layer 1

All conductive layers are then numbered sequentionally until the secondary side is reached
