要約(英語): This paper deals with charge-up characteristics of printed circuit (PC) board materials due to electrons penetrating inside a spacecraft body. Glass-fiber-reinforced plastic (GFRP) plates, typical PC board material, were irradiated by electron beam with the energy lower than 20keV simulating decelerated high-energy electrons penetrating through the satellite skin. The charge-up characteristics were obtained as parameters of irradiation time, the energy and the current density of the electron beam. The volume resistivities of the GFRP plates were also evaluated by the decay time constants of the surface potential after electron irradiation. The influence of a protective coating on the charging of the GFRP plates was also tested.
