Abstract: A computer-implemented method for classification of data by a machine learning system using a logic constraint for reducing a data labeling requirement. The computer-implemented method includes: generating a first embedding space from a first partially labeled training data set, wherein in the first embedding space, content-wise related training data of the first partially labeled training data are clustered together, determining at least two clusters in the first embedding space formed from the first partially labeled training data, and training a machine learning model based, at least in part, on a second partially labeled training data set and the at least two clusters, wherein the at least two clusters are used as training constraints.

Abstract: Manufacturing of flip-chip type assemblies is provided, and includes forming one or more contact elements of electrically conductive material on a carrier surface of at least one chip carrier, providing a restrain structure around the contact elements, depositing solder material on the contact elements and/or on one or more terminals of electrically conductive material on a chip surface of at least one integrated circuit chip, and placing the chip with each terminal facing corresponding contact elements. Further, the method includes soldering each terminal to the corresponding contact element by a soldering material, the soldering material being restrained during a soldering of the terminals to the contact elements by the restrain structure, and forming one or more heat dissipation elements of thermally conductive material on the carrier surface for facing the chip surface displaced from the terminals, where the one or more heat dissipation elements are free of any solder mask.

Abstract: Disclosed are embodiments of forming porous copper on the end of a copper pillar. The embodiments may be used to remove solder from selected locations on a chip or laminate substrate.

Abstract: An IC device package includes a carrier, one or more IC devices and a lid. The lid includes a lid-ridge. The lid is connected to the carrier by connecting the lid-ridge to the carrier with first nano particle metallic paste, prior to connecting the IC device to the carrier. Subsequent to connecting the IC device to the carrier, the lid is connected to the lid-ridge with second nano particle metallic paste. The nano particle metallic paste may be sintered to form a metallic connection. In multi-IC device packages, the lid-ridge may be positioned between the lid and the carrier and between the IC devices.

Abstract: A magnetic core comprises an anisotropic, composite material, which itself includes a matrix material (e.g., a dielectric, non-magnetic material, preferably a paramagnetic material), and magnetically aligned, ferromagnetic particles. The latter may for instance include micrometer- and/or nanometer-length scale particles. Such particles form chains of particles within the matrix material, wherein the chains form percolation paths of magnetic conduction. The paths extend along a first direction, whereby the chains extend, each, substantially along this first direction, while being distinct and distant from each other along a second direction that is perpendicular to the first direction and, possibly, to a third direction that is perpendicular to both the first direction and the second direction. Necking bridges are preferably formed between the particles. Related devices (e.g., inductor, amplifiers, transformers, etc.) and fabrication methods are also disclosed.

Abstract: The present invention is notably directed to a printed circuit board, or PCB. This PCB has two main surfaces, each delimited by lateral edges, as well as lateral surfaces, each meeting each of the two main surfaces at one lateral edge. The present PCB further comprises a row of solder pads, which extends along a lateral edge of the PCB. Each solder pad is formed directly at the lateral edge and/or directly on a lateral surface (meeting one of the two main surfaces at said lateral edge). I.e., each pad interrupts a lateral edge and/or an adjoining lateral surface. One or more chips, e.g., memory chips, can be mounted on such a PCB to form an IC package. The above solder pad arrangement allows particularly dense arrangements of IC packages to be obtained. The present invention is further directed to related devices and methods of fabrication thereof.

Abstract: A disconnect assembly includes a solid frame comprising a slit and a first liquid coolant circuit leading to a frame outlet defined in an inner wall of the slit. The assembly further includes an insert element, insertable in the slit so as to reach a sealing position. The latter defines a shut state, in which the insert element seals the frame outlet. The assembly includes a cold plate, comprising a second liquid coolant circuit with a duct open on a side of the cold plate. The cold plate can be inserted in the slit, so as to push the insert element, for the latter to leave the sealing position and the cold plate to reach a fluid communication position. This position defines an open state, in which the duct is vis-à-vis the frame outlet, to enable fluid communication between the first liquid coolant circuit and the second liquid coolant circuit.
