Abstract: Examples described herein relate to a tool-less manner of forming an assembly with a circuit board carrier enclosure that provide leaf springs that provide a force against a circuit board to maintain a level surface of the circuit board. Multiple leaf springs can be used to apply a desired force to the circuit board. A heat sink can be mounted in the enclosure at a distance from the circuit board. The circuit board with carrier can be inserted without tools into an electrical connection for communications with other devices.

Abstract: An apparatus is described. The apparatus includes a back plate. The apparatus includes a bolster plate that is secured to the back plate with a back bolt. The bolster plate has a window. The apparatus includes a circuit board between the back plate and the bolster plate. A semiconductor chip package is electro-mechanically coupled to the circuit board within the window. The apparatus includes a load stud that emanates from a face of the bolster plate. The back bolt emanates from an opposite face of the bolster plate. The load stud and back bolt are oriented along a same axis that is orthogonal to the face and the opposite face. The apparatus includes a heat sink. The apparatus includes a loading plate. The heat sink is mounted to the loading plate. The loading plate has a fixturing element that is secured to the load stud to secure the loading plate to the bolster plate.

Abstract: An apparatus is described. The apparatus includes a back plate, where, an electronic circuit board is to be placed between the back plate and a thermal cooling mass for a semiconductor chip package. The back plate includes a first material and a second material. The first material has greater stiffness than the second material. The back plate further includes at least one of: a third material having greater stiffness than the second material; re-enforcement wires composed of the first material; a plug composed of the second material that is inserted into a first cavity in the first material, a stud inserted into a second cavity in the plug. An improved bolster plate having inner support arms has also been described.

Abstract: Examples described herein relate to a cold plate. In some examples, the cold plate includes a surface with fins and at least two channels, wherein a first channel is shaped with a first opening extending towards the surface, a second opening proximate and across a first fin attached to the surface, and a third opening from the surface and extending away from the surface. In some examples, when a fluid is provided to the first opening, the first opening directs the fluid towards the surface, the second opening directs the fluid across the first fin, and the third opening directs the fluid away from the surface. In some examples, the second opening comprises split openings around opposite sides of the first fin.
