1. An interconnection between circuits, the interconnection comprising:

  • a first circuit defining a first surface and a second surface, the first circuit having at least one conductive pad, a relief vent formed through the first circuit conductive pad extending between the first and second surfaces of the first circuit;

    a spacer defining first and second surfaces, the spacer having at least one aperture alignable to the relief vent of the first circuit;

    a second circuit defining a first surface and a second surface, the second circuit having at least one conductive pad, a relief vent formed through the second circuit conductive pad extending between the first and second surfaces of the second circuit, the relief vent of the second circuit being alignable to the aperture of the spacer;

    solder paste disposed within the aperture of the spacer and between the first and second circuits, the solder paste disposed within the relief vents of the first and second circuits;

    wherein the first circuit is a flex circuit and the second circuit is a rigid circuit board.
