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 according to the

measurement techniques shown in the Isolation Glossary. Techniques such as inserting

grooves and/or ribs on a printed circuit board are used to help increase these

specifications.
