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 invention relates to a method of manufacturing a charge dissipative surface layer on a member made from or consisting of a dielectric polymeric material or polymer-based composite which is intended to be used in space and other extreme environments, the member having at least one surface, in particular two opposing surfaces, each of the surfaces having a flat or a three-dimensional shape. The method comprises the steps of carbonizing the at least one surface of the member in a vacuum environment through ion bombardment with simultaneous surface renewal in a dynamic way, by bombardment of the at least one surface with an ion beam formed in a gaseous linear high-current technological ion beam source of rare gas and added predetermined amount of a carbonaceous gas in the same ion beam gas admixture in order to achieve a treated carbonized surface layer with a uniform surface resistivity in a charge-dissipative range.

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. ...
