WebThe “comparative tracking index” or “tracking resistance” is an indication of how well an insulating material withstands certain loads on its surface. In even more general terms, tracking resistance is an indication of how resistant a material is to environmental influences. Other loads occur in practice alongside partial discharges ... WebWhat is Comparative Tracking Index(CTI)? Here CTI is a quality item that refers to copper clad laminate which is widely used in home electrical appliance or other high-voltage(110V, 220V) electrical apparatus.It is a simulated conditon that the PCB is polluted in its working environment, which result in leakage or short-circuit at the track gap of the PCB surface, …

WebJun 28, 2024 · High voltage parts on a printed circuit board. ... For instance, the default CTI value for FR-4 is 175, while other more specialized materials can have a CTI value as high as 600. Different documents cover PCB creepage and clearance standards, with the primary one being IPC-2221. This is a general standard that covers many different design ... 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. earth mephit pf2e

WebThe CTI value is tested in accordance with 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 can withstand 50 drops of 0.1% chlorine The highest voltage value (V) at which an aqueous solution of ... WebCTI Systems is a manufacturer of conveyor systems for non-electronic manufacturers and custom automation for a variety of applications ranging from custom work cells to custom assembly lines. Our printed circuit board (PCB) Depaneling division began in 2001, and our original machines are still in operation at high volume automotive ... WebDec 26, 2024 · The CTI defines the voltage at which an insulating material like a PCB substrate begins to break down near the surface. During breakdown, the material begins to carbonize and becomes more conductive, which increases leakage current and accelerates breakdown over time. ctimsm
