Splet14. jun. 2024 · Comparative Tracking Index (CTI) is the extent to which the insulating material of the PCB can resist the unwanted current to flow between traces on the board. It is a measure of the ability of the PCB substrate to withstand any breakdown between two tracks on the PCB surface. SpletIl Comparative Tracking Index o CTI è usato per misurare la capacità di tenuta di un materiale isolante alle scariche superficiali (chiamate "tracce" o "electrical breakdown").In francese è chiamato "Indice de cheminement". La "traccia" è un percorso conduttivo (carbonizzato) che si forma in modo progressivo sulla superficie di un materiale isolante …
