    Abstract: Embodiments include a reflowable grid array (RGA) interposer, a semiconductor packaged system, and a method of forming the semiconductor packaged system. The RGA interposer includes a substrate having vias and zones, where the zones have embedded heaters. The heaters may include first traces, second traces, and via filament interconnects. The vias may have a z-height greater than a z-height of the heaters, and each of the zones may have a grid pattern. The RGA interposer may include first and second layers in the substrate, where the first layer includes the first traces, the second layer includes the second traces, and the second layer is over the first layer. The grid pattern may have parallel first traces orthogonal to parallel second traces to form a pattern of squares, where the pattern of squares has the first traces intersect the second traces substantially at right angles.

    Abstract: Examples described herein relate to a system. The system can include a container that contains fluid to provide two phase immersion liquid cooling (2PILC) for a system within the container. The container can enclose a first circuit board with a first side of the first circuit board is conductively coupled to at least one device. The container can enclose a motherboard conductively coupled to a second side of the first circuit board with a first side of the motherboard is conductively coupled to the second side of the first circuit board. The motherboard can include at least four edges. Connectors can conductively connect the motherboard with a second circuit board. The second circuit board can include at least four edges and an edge of the motherboard is oriented approximately 90 degrees to an edge of the second circuit board. At least one device can include one or more of: a processor, memory device, accelerator device, or network interface.

    Abstract: Embodiments include a reflowable grid array (RGA) interposer, a semiconductor packaged system, and a method of forming the semiconductor packaged system. The RGA interposer includes a plurality of heater traces in a substrate. The RGA interposer also includes a plurality of vias in the substrate. The vias extend vertically from the bottom surface to the top surface of the substrate. The RGA interposer may have one of the vias between two of the heater traces, wherein the vias have a z-height that is greater than a z-height of the heater traces. The heater traces may be embedded in a layer of the substrate, where the layer of the substrate is between top ends and bottom ends of the vias. Each of the plurality of heater traces may include a via filament interconnect coupled to a power source and a ground source. The heater traces may be resistive heaters.
