Abstract: In one example, a micro device includes a housing; a chip package disposed in the housing; a noise producing component coupled to the housing. The micro device also includes a noise reduction system having a reference microphone for detecting a noise from the noise producing component and a controller configured to receive the noise from the reference microphone and generate a masking sound signal in response to the detected noise. A speaker is coupled to the housing for producing a masking sound corresponding to the masking sound signal, whereby the masking sound reduces the noise. In another example, the noise producing component comprises a fan.

Abstract: A method of attaching a chip package to a printed circuit board (“PCB”) is provided, along with an electronic device fabricated using the method. The method includes measuring a warpage parameter of the chip package and selecting a stencil configured to compensate for warpage corresponding to the measured warpage parameter. The stencil includes a plurality of apertures. The selected stencil is positioned above the PCB, and solder paste is applied on the PCB via the plurality of apertures of the stencil. Thereafter, the PCB is moved away from the stencil. The chip package is positioned on the solder paste on the PCB, thereby attaching the chip package to the PCB.

Abstract: Chip packages, electronic devices and method for making the same are described herein. The chip packages and electronic devices have a heat spreader disposed over a plurality of integrated circuit (IC) devices. The heat spreader has an opening through which a protrusion from an overlaying cover extends into contact with one or more of the IC devices to provide a direct heat transfer path to the cover. Another one or more other IC devices have a heat transfer path to the cover through the heat spreader. The separate heat transfer paths allow more effective thermal management of the IC devices of the chip package.

Abstract: Chip packages and methods for fabricating the same are provided which utilize a first heat spreader interfaced with a first integrated circuit (IC) die and a second heat spreader separately interfaced with a second IC die. The separate heat spreaders allow the force applied to the first IC die to be controlled independent of the force applied to the second IC die.

Abstract: Some examples described herein provide for a heterogeneous integration module (HIM) that includes a thermal management apparatus. In an example, an apparatus (e.g., a HIM) includes a wiring substrate, a first component, a second component, and a thermal management apparatus. The first component and the second component are communicatively coupled together via the wiring substrate. The thermal management apparatus is in thermal communication with the first component and the second component. The thermal management apparatus has a first thermal energy flow path for dissipating thermal energy generated by the first component and has a second thermal energy flow path for dissipating thermal energy generated by the second component. The first thermal energy flow path has a lower thermal resistivity than the second thermal energy flow path.

Abstract: A chip package assembly and method for fabricating the same are provided which utilize a plurality of electrically floating heat transfer structures for improved thermal management. In one example, a chip package assembly is provided. The chip package assembly includes a substrate, a first integrated circuit (IC) die and a plurality of electrically floating conductive heat transfer structures. The substrate has a first surface and an opposing second surface. The first IC die has a first surface, an opposing second surface, and four lateral sides. The second surface of the first IC die is mounted to the first surface of the substrate. The plurality of electrically floating conductive heat transfer structures extend in a first direction defined between the first and second surfaces of the first IC die. A first conductive heat transfer structure of the plurality of electrically floating conductive heat transfer structures are part of a first conductive heat transfer path having a length in the first direction at least as long as a distance between the first and second surfaces.
