WebMar 2, 2024 · The CTI value is measured according to the IEC-112 standard method "Test Method for Comparative Tracking Index of Substrates, Printed Circuit Boards and Printed Circuit Board Assemblies", which means that the surface of the substrate withstands 50 drops of 0.1% chlorine The highest voltage value (V) at which ammonium chloride … WebAug 9, 2001 · Comparative Tracking Index [CTI]. In printed circuit board fabrication, CTI is a measure of the ability of the laminate surface to withstand tracking [carbonneous tracks on the surface, under wet contaminated conditions] across two electrodes placed on the surface, when an electrolyte is dropped between them. It is a test of the bare laminate.
