1. An electronics assembly, comprising:
a heat sink;
a printed circuit board;
a press-fit terminal extending through the printed circuit board for thermally connecting the printed circuit board to the heat sink in an assembled state, the terminal including a first elastic portion engaging with the printed circuit board, and a second elastic portion spaced apart along an axial length of the terminal from the first elastic portion and including two opposing elastic arms compressible in a radial direction for fixing the printed circuit board to the heat sink; and
a spacer arranged between the heat sink and the printed circuit board and including an aperture formed therethrough for receiving at least a portion of the terminal, the spacer directly contacting the printed circuit board and the heat sink uniformly about a circumference of the aperture,
wherein the first elastic portion includes two opposing elastic arms compressible in a radial direction for fixing the terminal to the printed circuit board, the terminal further including an intermediate portion arranged between the first and second elastic portions and defining a first surface opposing the printed circuit board in an insertion direction of the first elastic portion and a second surface opposing the heat sink in an insertion direction of the second elastic portion for fixing a distance between the printed circuit board and the heat sink in the assembled state, and
wherein the intermediate portion includes a first plurality of radially extending portions defining the first surface and engaging with the printed circuit board and a second plurality of radially extending portions defining the second surface and engaging with the heat sink.
