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. WebCTI of ordinary FR-4 substrate material is approximately 200V while high-CTI substrate material is generally required to be over 600V. High-CTI substrate material can be obtained through picking up special epoxy resin, high leakage tracking material and glass fiber. • Low-Dk Epoxy Resin
