1. An assembly comprising:
- a panel comprising a first surface;
a first active circuit coupled to the first surface of the panel;
a cold plate having a first bore and comprising;
a first inner surface exposed by the first bore; and
a second surface facing the first surface of the panel;
a first thermally conductive material in contact with the first inner surface of the cold plate and the first active circuit and forming a thermal conductive path from the first active circuit to the cold plate that extends only through the first thermally conductive material, the first thermally conductive material being in direct contact with the second surface of the cold plate; and
a mask layer in direct contact with the second surface of the cold plate, the mask layer being resistant to bonding to the first thermally conductive material, the mask layer not being part of the thermal conductive path,wherein an opening of the bore is completely filled with only the first thermally conductive material.
