11. An electronics assembly, comprising:a chassis;
a circuit board coupled to the chassis;
a support structure coupled to the chassis and spatially separated from the circuit board, and comprising an array of apertures;
a plurality of electronics components electrically coupled to the circuit board and extending through respective apertures of the support structure;
a plurality of first mounting collars attached to the support structure for mounting respective electronics components to the support structure; and
a plurality of second mounting collars attached to the support structure for mounting respective electronics components to the support structure, the second mounting collars arranged in an alternating manner relative to the first mounting collars,
wherein the first mounting collars are nested relative to adjacent second mounting collars to maximize the density of the electronics components relative to the circuit board.
