(1) Creepage and clearance requirements should be applied according to the specific equipment isolation standards of a specific
application. Care should be taken to maintain the creepage and clearance distance of the board design to ensure that the mounting
pads of the isolator on the printed circuit board (PCB) do not reduce this distance. Creepage and clearance on a PCB become equal
according to the measurement techniques shown in the Isolation Glossary section. Techniques such as inserting grooves and/or ribs on
the PCB are used to help increase these specifications.
