PRINTED-CIRCUIT BOARD FOR SPACECRAFT ON-BOARD RADIO-ELECTRONIC EQUIPMENT Russian patent published in 2013 - IPC H05K1/03 B82B1/00 B82B3/00 

FIELD: radio engineering, communication.

SUBSTANCE: in a printed-circuit board for spacecraft on-board radio electronic equipment, which comprises a dielectric substrate and an electric circuit formed thereon, the substrate is made from dielectric material with volume resistivity selected based on the condition 10¹¹ Ohm·cm≥ρ_v≥10⁵ R_max • d, where ρ_v is the volume resistivity of the dielectric material of the substrate of the printed-circuit board, Ohm·cm, R_max is the maximum resistance of the resistor included in the electric circuit on the printed-circuit board, Ohm, d is the thickness of one dielectric layer of the printed-circuit board. The dielectric material used is a composite dielectric material which contains a conducting additive selected from: fine acetylene soot in amount of 5-6.5% of the weight of binder, molecular fullerene C₆₀ or C₇₀ in amount of 1-2% of the weight of binder, carbon nanotubes in amount of 0.3-0.9% of the weight of binder.

EFFECT: making a printed-circuit board for spacecraft on-board radio-electronic equipment which is resistant to electrostatic charging effects.
