NOTE

Creepage and clearance requirements should be applied according to the specific

equipment isolation standards of an application. Care should be taken to maintain the

creepage and clearance distance of a board design to ensure that the mounting pads of

the isolator on the printed-circuit board do not reduce this distance.

Creepage and clearance on a printed-circuit board become equal in certain cases.

Techniques such as inserting grooves and/or ribs on a printed circuit board are used to

help increase these specifications.
