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. 4 Submit Documentation Feedback Copyright © 2011–2013, Texas Instruments Incorporated Product Folder Links: AMC1204 AMC1204B |
