Claim 13:
14. 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 contact plate attached and thermally coupled to said cold plate;
a sample printed circuit board (PCB) incorporating a quantum integrated circuit (IC) die to be cooled to said first cryogenic temperature;
a first plurality of spring loaded mounting screws adapted to mechanically fasten said sample 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; and
a second plurality of spring loaded mounting screws adapted to mechanically fasten a flexible printed cable terminated with a PCB and connecter therein to said sample PCB.
