1. A cable assembly comprising:
- a top metal shield and a bottom metal shield, wherein one of the top and bottom metal shields comprises an embossment and the other of the top and bottom metal shields comprises a recess or through hole to mate with the embossment and form a shield cavity;
a printed circuit board assembly (PCBA), including at least one integrated circuit (IC), disposed within the shield cavity;
at least one electrically isolative film sheet disposed within the shield cavity and between the PCBA and the top or bottom metal shield;
a raw cable sub-assembly further comprising;
a plurality of wires terminated at the PCBA, the plurality including at least a micro-coaxial signal wire, a power wire, and a ground wire; and
an electrically isolative jacket surrounding the plurality of wires; and
a single piece boot surrounding the raw cable sub-assembly, the top shield and the bottom shield.

Abstract
An active electric cable assembly suitable for high speed communication (e.g., 10 Gbit/sec) between electronic devices, such as but not limited to a peripheral device (e.g., storage device, docking station, etc.) and a computing platform expansion bus. (e.g., supporting the standards and specifications associated with the trade name Thunderbolt®). In embodiments, through holes, embossments, mechanical stops, micro-coaxial single wires, thermal pads, and dielectric film sheets are utilized in a robust cable assembly.

14. A method of assembling an cable assembly, the method comprising:
-
soldering a plurality of wires extending from a raw cable sub-assembly to metal pads disposed on a first end of a printed circuit board assembly (PCBA); inserting a second end of the PCBA, opposite the first, into a plug housing contact sub-assembly to couple pins of the plug housing contact sub-assembly with metal pads disposed on the second end of the PCBA; inserting the PCBA into the bottom metal shield to contact stops on the PCBA with sides of the bottom metal shield; disposing at least one electrically isolative film sheet between the PCBA and the sides of the bottom metal shield; mating an embossment in one of the bottom and top metal shields with a recess or through hole in the other of the bottom and top metal shields to surround the PCBA within a shield cavity; and inserting the mated top and bottom metal shields into a single-piece boot until a recess in at least one of the boot or shields latches with an embossment in the other of the boot or shields. - View Dependent Claims (15, 16)
