Method of assembling a circuit board assembly

A method for assembling a circuit board assembly comprising steps of:

• providing a package substrate with a silicon chip and an array of contact pads provided by a conductive material;
• affixing a plurality of conductive springs to the array of contact pads for providing conductive contact with a corresponding array of contacts on a circuit board assembly;
• providing a printed circuit board with an array of contact pads corresponding to the array of contact pads on the silicon chip package;
• assembling the silicon chip package to the printed circuit board such that the plurality of springs are in conductive contact with the array of contact pads on the printed circuit board;
• providing the printed circuit board with one of a plurality of pins and apertures;
• providing the package with the other of a plurality of pins and apertures;
• and
• inserting the pins into the apertures while assembling the package to the printed circuit board to align the springs with the array of contacts of the printed circuit board.
