The electronics industry is moving away from static PDFs.
The standard specifies the maximum allowable amount a component can hang over the edge of a pad. For Class 3, side overhang cannot exceed 25% of the component termination width.
Many aerospace and defense contracts written in 2015–2020 specifically cite as the governing standard. Changing to a newer revision mid-contract requires massive internal re-certification. Therefore, engineers still need the F revision PDF for daily reference.
Class 2 requires a minimum of 50% solder fill in the barrel, while Class 3 demands a minimum of 75% fill. ipc-a-610f pdf
