Embodiment IE

[0109] 50 standard FCCs of different sizes (105mm, 205mm) with the same standard as CE were treated with the following ion beam process:

[0110] Equipment: KVARC-700 high vacuum with rotating drum (0.5m wide, stainless steel)

[0111] Process conditions:

[0112] - Starting vacuum is about 3×10 -3 Pa; vacuum baked at 35°C for 2 hours before processing

[0113] - using argon (92 volume %) and acetylene (C 2 h 2 , 8 vol%) mixture of linear ion beam sources

[0114] - Ion beam energy 2.5-3keV; ion beam current 195mA; bias on drum 150V

[0115] -Temperature <65°C; treatment duration 16 minutes

[0116] - Treat the second surface in a separate process using the same process conditions

[0117] -Fix the FCC to the drum and mask the copper ends and adjacent edges of the Kapton surface with polyimide pressure sensitive tape (CGSTAPE-8358, 1 inch) with silicone adhesive

[0118] Both sides of 50 FCCs were processed in several rounds of the process.

[0119] All bulk and surfa...

Abstract

The present invention relates to a method for the manufacture of charge dissipating surface layers on components made of or consisting of dielectric polymeric materials or polymer-based composite materials intended for use in space and other extreme environments, said components having at least A surface, in particular, has two opposing surfaces, each of which has a planar shape or a three-dimensional shape. The method comprises the steps of carbonizing at least one surface of the component by ion bombardment in a vacuum environment while dynamically renewing the surface, said step utilizing a gaseous linear high current technology ion beam source in a noble gas bombarding the at least one surface with the formed ion beam and a predetermined amount of carbon-containing gas added in the ion beam gas blend to obtain a treated carbonized surface having a uniform surface resistivity in the range of charge dissipation Floor.

Description

technical field [0001] The present invention relates to a method of manufacturing a charge dissipating surface layer on a component made of or consisting of a dielectric polymer-based material intended for use in space, and to such component. [0002] In particular, the present invention relates to the surface treatment of dielectric polymeric materials having shaped and / or grooved polymeric surfaces, the treatment of surfaces embedded with inorganic particles, or the treatment of dielectric polymeric composites with inorganic particulate or fibrous fillers. field of processing. Polymer-based devices such as spacecraft or solar array components such as Flat Cable Conductors (FCC) that provide long-term durability for charge dissipation and other functional properties in GEO space, or in GEO space and other extreme environments This charge dissipation effect Polymer composite-based materials and devices with long-term durability require charge-dissipating surface properties. ...
