Abstract
A system for matching impedance in a flexible trace interconnect array. The array comprising a flexible dielectric film, a plurality of trace conductors disposed along a longitudinal axis of the dielectric film, and a shield disposed along a section of the array, wherein at least one parameter of at least one of an unshielded section and of the shielded section is selected such that impedance of the unshielded section and impedance of the shielded section are substantially the same.

A flexible trace interconnect array, the array comprising:
- a flexible dielectric film;
- a plurality of trace conductors disposed along a longitudinal axis of the dielectric film;
- and
- a shield disposed along a section of the array, wherein at least one parameter of at least one of an unshielded section and of the shielded section is selected such that impedance of the unshielded section and impedance of the shielded section are substantially the same.
A method for matching impedance between a shielded section and an unshielded section of a flexible trace interconnect array, the method comprising:
- disposing a plurality of trace conductors along a longitudinal axis of a flexible dielectric film, and a shield along a section of the array;
- and
- selecting at least one parameter of at least one of the unshielded section and of the shielded section such that impedance of the unshielded section and impedance of the shielded section are substantially the same.
A flexible trace interconnect array, the array comprising:
- a flexible dielectric film;
- and
- a plurality of trace conductors disposed along a longitudinal axis of the dielectric film, wherein a first section of the array has a first trace conductor impedance, a second section of the array has a second trace conductor impedance, at least one parameter of at least one of the first section and of the second section is selected such that impedance of the first section and impedance of the second section are substantially the same, and the selected parameter is varied gradually along the longitudinal axis at an intersection of the first section and the second section such that wave reflection of signals presented by the array due to impedance mismatch is reduced.
