Effect of intrinsic PCB parameters on the performance of fluoropolymer coating under condensing humidity conditions

Optical Detection Method for Partial Discharge of Printed Circuit Boards in Electrified Aircraft Under Various Pressures and Voltages

“…Regarding PDs on PCBs, there are several studies about the breakdown characteristics and PD testing of PCBs under ac 50-Hz voltage, but there are few investigations of the PD characteristics on PCBs under ac voltage for other frequencies and square voltages, which are prevalent in real MEA/AEA power system [13]- [15]. Some work about the effect of conformal coating and the influence of external environmental changes on PCB PDs is done [16], [17]. However, these studies mainly focus on the electrical and physicochemical properties of the PCB itself, which cannot be applied to detect and forewarn about the PDs in MEA/AEA.…”
