(1) Creepage and clearance requirements are 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.
