Trans-vacuum printed flexible wiring apparatus

A trans-vacuum flexible wiring apparatus for use in a cryostat, comprising:

• a continuous annular shaped laminated flexible material having a concentric sealing region able to be vacuum sealed between a cover plate and a perimeter of a hole in a vacuum chamber of the cryostat and whose outer perimeter is offset from an outer shape of the cover plate;
• and
• a plurality of electrically conductive printed traces that axially cross said annular laminated flexible material thereby passing signals between one or more first flexible tabs from an air side of the cryostat and one or more second flexible tabs on a vacuum side of the cryostat.

The trans-vacuum flexible wiring apparatus according to claim 15, wherein

• said plurality of electrically conductive traces pass axially through one or more first tabs extending out of said annular shaped sealing region to the air side of the cryostat and terminate in a flat rigid multi-contact connector printed circuit board (PCB);
• and
• said plurality of electrically conductive traces pass axially through one or more second tabs extending out of said annular shaped sealing region towards its center to the vacuum side of the cryostat and terminate in a flat rigid multi-contact connector printed circuit board (PCB).

The trans-vacuum flexible wiring apparatus according to claim 15, further comprising annular concentric vacuum seals on either side of said annular shaped sealing region that are operative to compress and seal said annular shaped region therebetween.

The trans-vacuum flexible wiring apparatus according to claim 15, wherein said annular concentric vacuum seals are selected from the group consisting of elastomeric O-rings, non-elastomeric O-rings, and crush seals.

A trans-vacuum flexible wiring apparatus for use in a cryostat, comprising:

• a flat laminated flexible material having a plurality of printed layers and an annular shaped sealing region able to be vacuum sealed between a cover plate and a perimeter of a hole in a vacuum chamber of the cryostat;
• and
• a plurality of electrically conductive traces fabricated on said plurality of printed layers that cross said annular shaped region thereby passing electrical signals between an air side and a vacuum side of the cryostat.
