1. A sample board apparatus for use in a cryostat, comprising:
a cold plate attached to a second stage of a cryostat and maintained at a first cryogenic temperature;
a plurality of pillar spacers attached and thermally coupled to said cold plate;
a contact plate attached and thermally coupled to said plurality of pillar spacers;
a sample printed circuit board (PCB) incorporating a quantum integrated circuit (IC) die to be cooled to said first cryogenic temperature; and
a first plurality of spring loaded mounting screws adapted to mechanically fasten said PCB to said contact plate suspending it therefrom to allow for differential thermal expansion and contraction and to provide a capability of adjusting an amount of force applied between said quantum integrated circuit (IC) die and said contact plate.
