Dielectric Withstand Voltage Test (DWS) or High Potential Test (HiPot)
Conductive Anodic Filament Test (CAF)
Typical Proof Test (VDC) Proof Test or High Potential Test (HiPot)
Typical Proof Test (VDC) High Potential Dielectric Testing (HiPot)
Breakdown (kV AC) Voltage Test
Breakdown (kV AC) Dielectric Breakdown Voltage
Typical thermal management aluminum LED PCB materials are modified to have higher thermal conductivity. The modifications of the dielectric material raise the Dk of the material to the range of 6 or higher.
