Abstract: Techniques for liquid cooling systems are disclosed. In one embodiment, a hermetically sealed container includes an integrated circuit component and a two-phase coolant. As the integrated circuit component generates heat, the coolant boils, rising to a lid of the container. A cold plate mated with the lid absorbs heat from the lid, causing condensation of the coolant on the underside of the lid. The coolant then drips back down towards the integrated circuit component. Other embodiments are disclosed.

Abstract: A processor unit module comprises an integrated circuit component attached to a top side of a printed circuit board and one or more electronic components (e.g., voltage regulator FETs, inductors) attached to a bottom side of the board. The printed circuit board is located between a top stiffener plate and a bottom stiffener frame and the three components are secured together by fasteners that connect the top stiffener plate to the bottom stiffener frame. Flexible thermal straps connect the top stiffener plate to one or more slugs located between the printed circuit board and the bottom stiffener frame. The slugs touch the bottom side of the board and are held in place by the bottom stiffener frame. Heat generated by the bottom side components is transported by the slugs and the thermal straps to a thermal management solution (e.g., heat sink, cold plate) attached to the top side of the module.

The second container is sealed to separate the first liquid coolant from the second liquid coolant. Other embodiments may be described and/or claimed.

Abstract: A variable conductance heat pipe (VCHP) is utilized as a “passive heat switch” to regulate a characteristic temperature of an integrated circuit component. The VCHP is located between an integrated circuit component and a cold plate and comprises a working fluid and a non-condensable gas in a chamber. When the component is not operational, the VCHP blocks the flow of heat from the component to the cold plate. As component power consumption increases, the working fluid pressure increases and compresses the non-condensable gas toward the cooler region of the cold plate to eventually create a low thermal resistance path between the component and the cold plate. By introducing negative feedback into the thermal management solution, the VCHP keeps the characteristic temperature within a narrow range. This can alleviate stress on package components (e.g., solder joints) due to excessive thermal cycling, which can extend the lifetime of the component.

Abstract: A method for assembling a printhead such as an ink jet printhead can include the use of a laser to bond two or more printhead layers together. In an embodiment, a laser beam is directed through a transparent layer to an energy-absorbing layer, where the energy-absorbing layer is melted such that after removal of the laser beam the melted layer solidifies to adhere the energy-absorbing layer to the transparent layer. In another embodiment, heating the energy-absorbing layer melts the transparent layer to adhere the energy-absorbing layer to the transparent layer after removal of the laser beam. The laser transmission lamination process described can result in a fluid-tight seal which requires less processing time and materials over an adhesive-based process.

In an embodiment, an ultrasonic frequency is directed to an interface between a first layer and a second layer to generate heat at the interface. In an embodiment, the heat melts at least one of the first layer and the second layer, and the layers are cooled to cure the melted layer. In another embodiment, the heat generated using the ultrasonic frequency cures an adhesive layer between the first layer and the second layer. The ultrasonic lamination process described can result in a fluid-tight seal which requires less processing time and materials over an adhesive-based process.

A blanket metal layer, a blanket piezoelectric element layer, and a blanket conductive layer can be formed over a semiconductor substrate such as a semiconductor wafer or wafer section. The piezoelectric element layer and the blanket conductive layer can be patterned to provide a plurality of transducer piezoelectric elements and top electrodes respectively, while the metal layer forms a bottom electrode for the plurality of transducers. Subsequently, the semiconductor substrate can be patterned to form a body plate for the print head jet stack. Forming a print head jet stack using semiconductor device manufacturing techniques can provide a high resolution device with small feature sizes.
