  • PCB Line Spacing for Creepage and Clearance

    2020-12-11u2002·u2002CTI values help to deduce the overall PCB tracking resistance. These values give an estimation for leakage or short-circuit as trace spacing becomes small due to component density. As per the IEC-60112 standard, a higher CTI grade substrate offers good resistance to electrical breakdown. CTI is a critical number while selecting a PCB material.
