1. A ribbon cable, comprising:
a first insulative layer extending along a length and a width of the ribbon cable and comprising opposing top and bottom major surfaces and defining a plurality of spaced apart cavities therein extending between the top and bottom major surfaces of the first insulative layer, the top major surface of the first insulative layer deformed in a plurality of spaced apart substantially parallel regions extending along the length, and arranged along the width, of the ribbon cable, each deformed region having a shape of a groove and comprising a deformed portion of at least one cavity in the plurality of spaced apart cavities; and
a plurality of spaced apart substantially parallel conductors extending along the length of the ribbon cable, each conductor disposed in a corresponding deformed region of the first insulative layer,
wherein the plurality of spaced apart cavities is independent of the plurality of substantially parallel regions and forms a regular two-dimensional array of cavities arranged along the length and width of the first insulative layer.
