Acceptance criteria according to IPC-A-610 and layout

In layout, minimum distances between pads and traces are typically determined based on dielectric strength. Often the IPC-A-610 acceptance criteria are not taken into account.

For example, a chip component of size 0805 is 2.0 x 1.25 mm long or wide. corresponding to class 2, an overhang of the component of 0.62 mm and for class 3 of 0.31 mm would be IPC-compliant, provided that the minimum electrical isolation distance is not offset.

The minimum electrical insulation distance is usually not known during production. For this reason, half the distance (relative to the outer edge of the pad) to the next potential (conductor track, pad) is usually assumed here.
