Various parameters may be used to form the array and position the coaxial cables 104, 106, 108 and the drain wire 114 properly. For example, and referring now to FIGS. 7A and 7B, the coaxial cables 104, 106, 108 and the drain wire 114 may be disposed within the outer jacket 102 according to a grid 702 to create a uniform spacing between cables/wires to match a pitch on the BGA 404. In one embodiment, the grid 702 may be created by positioning the cables/wires within the array to match the pitch and holding them in position with the outer jacket 102. Additionally or alternatively, the spacing may be maintained according to the outer diameter of one or more of the coaxial cables 104, 106, 108. For example, and referring now to FIGS. 6C and 6D, the dielectric 112 thickness may be selected to support a desired outer diameter of the corresponding coaxial cable. Similarly, other components making up the coaxial cable may be adjusted to alter the outer diameter of the corresponding coaxial cable. Therefore, the positioning of the coaxial cables within the array may be modified or optimized to provide a desired spacing between the center conductors 110 of the cable assembly 100, create a desired overall size of the cable assembly 100, and/or engage a particular interface, such as a ball grid array or circuit board.
