Abstract:
An electrical assembly comprises a substrate having a dielectric layer and one or more electrically conductive traces overlying the dielectric layer. An electrical component is mounted on a first side of the substrate. The electrical component is capable of generating heat. A plurality of conductive through holes in the substrate are located around a perimeter of the electrical component. The conductive through holes are connected to a conductive trace for heat dissipation. A cooling cavity has bores that face a second side of the substrate opposite the first side. A plurality of respective compliant pins are inserted into corresponding conductive through holes and the bores, wherein a generally exposed portion of the compliant pin is exposed to air or a coolant liquid within the cooling cavity.

Abstract:
The current invention relates to a system for fast and accurate filling of a two- phase cooling device, comprising a binding device (30) intended to be hermetically mounted onto the cooling device, the binding device (30) comprising a through-hole (32) able to be in fluid contact with the cooling device, said through-hole (32) being extending between a lower surface adapted to the cooling device's surface, and an essentially plane upper surface, the binding device (30) further comprising a gripping head essentially level with said upper surface, allowing for a filling tool (400) to be put in hermetic contact with said upper surface. In a preferred embodiment, the through-hole (32) can be hermetically sealed by forced insertion of a pin- shaped plug (33). The invention also relates to the filling tool (400) to be used in combination with the binding device (30), allowing gas removal from the cooling device, filling of a working fluid, and hermetic sealing of the cooling device. The invention also relates to the high accuracy of filling by using zero dead volume valves. The binding device (30) is notably particularly well adapted for use in an automated process.
