A cooling structure for large electronic boards with closely-spaced heterogeneous die and packages is disclosed. The assembly includes a frame having a plurality of openings. The assembly further includes a cold plate mounted to the frame. The cold plate includes at least one inlet and at least one outlet and fluid channels in communication with the at least one inlet and the at least one outlet. The assembly further includes a heat sink mounted within each of the plurality of openings which in combination with sidewalls of the openings of the frame and the cold plate form individual compartments each of which are in fluid communication with the fluid channels.

A laminate includes a plurality of buildup layers disposed on a core and a plurality of unit cells defined in the buildup layers. Each unit cell includes: at least one test via that passes through at least two of the buildup layers and that is electrically connected to testing locations on a probe accessible location of the laminate; and two or more dummy vias disposed in the unit cell. The dummy vias are arranged in the unit cell at one of a plurality of distances from the test via.

Test cell for laminate and method

Methods, systems and apparatus for automatically ensuring passenger safety by identifying article(s) in need of securing in a vehicle and attaching at least one wireless signaling component to each article. Each wireless signaling component includes a wireless signaling device and a mechanical blocking device that controls a wireless signal emitted from the wireless signaling device. The emitted wireless signaling indicates a state of the article. State information relating to a state of each article is generated and received at a data network device, which generates state results based on this state information. The state results are output to an end user, whereby the state results identify those articles that are secured, unsecured, and/or improperly secured, for automatically ensuring passenger safety.

An integrated circuit screen printing nozzle that has a nozzle body, a first inner layer on the nozzle body, a second outer layer on the first layer, and an opening through the nozzle body, the first layer, and the second layer. The first and second layers can be an insert held within the body. The opening allows paste material to flow through the screen printing nozzle to the stencil mask. Also, the second outer layer includes a contact surface adapted to contact the stencil mask. One feature of the invention is that the first layer is softer (has a lower durometer) than the second layer. This allows the second layer to be more durable than the first layer and for the first layer to provide additional flexibility to the second layer. Therefore, the invention provides a nozzle that has the high durability characteristics of a hard outer surface with the compliance of a soft nozzle.

An apparatus in which opposed nozzle assemblies are utilized to clean residual material, such as a metallic paste, from an article, such as a screening mask. Each of the nozzle assemblies has a first set of nozzles for spraying a cleaning agent onto the article in a first pattern to first chemically and mechanically remove residual material from the article. At least one of the nozzle assemblies has a second set of nozzles for spraying a cleaning agent onto the article in a second pattern while simultaneously applying a voltage between the second set of nozzles and the article to then chemically and electrolytically remove the remaining residual material from the article.

Screening of a workpiece utilizing a screening apparatus which includes a paste dispensing apparatus and a trailing squeegee assembly in close proximity to the paste dispensing apparatus. When the screening apparatus is operable, the squeegee assembly is in contact with the workpiece at the same time as a paste is dispensed from the paste dispensing apparatus.
