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 10Ohm·cm???10R? d, where ?is the volume resistivity of the dielectric material of the substrate of the printed-circuit board, Ohm·cm, Ris 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 Cor Cin 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.2 cl |
