  • Publication number: 20230405643
    Abstract: An embodiment system, configured to clean a semiconductor package assembly, may include a sprayer device including a plurality of nozzles configured to direct a pressurized cleaning fluid toward the semiconductor package assembly; a conveyor configured to move the semiconductor package assembly relative to the sprayer device along a first direction; and a dryer spatially displaced from the sprayer device and configured to direct a pressurized gas flow toward the semiconductor package assembly to remove cleaning fluid introduced by the sprayer device. Each of the plurality of nozzles may be displaced from one another along a second direction to thereby generate respective separate spray distribution patterns. Adjacent nozzles may be further displaced from one another along a third direction to thereby a reduce an overlap of adjacent spray distribution patterns relative to a configuration in which the adjacent nozzles are not displaced from one another along the third direction.

  • Publication number: 20230386875
    Abstract: An under boat support (UBS) includes an electrostatic discharge (ESD) safe ceramic body and a conductive body. The ESD safe ceramic body is coupled to a surface of the conductive body by an adhesive, which may be resistant to high temperatures. A plurality of springs are present within the adhesive and extend from the surface of the conductive body to a surface of the ESD safe ceramic body. For example, first ends of the plurality of springs are electrically coupled to the surface of the conductive body, and second ends of the plurality of springs, which are opposite to corresponding ones of the first ends of the plurality of springs, are electrically coupled to the surface of the ESD safe ceramic body. The plurality of springs form electrical pathways such that the ESD safe ceramic body is electrically coupled to the conductive body.

  • Publication number: 20230377910
    Abstract: An apparatus for cleaning a package device is provided. The apparatus includes a package device loader; a package device unloader; a first cleaning area disposed between the package device loader and the package device unloader; and a conveyor. The conveyor includes a frame extending from the package device loader to the package device unloader and through the first cleaning area; and a belt wrapping the frame, wherein the belt includes a movable upper surface between the package device loader and the package device unloader, wherein the movable upper surface is configured to move relative to and over the frame, and a first distance between the movable upper surface and the frame in the first cleaning area increases in a direction from the package device loader to the package device unloader.

  • Publication number: 20230351577
    Abstract: A method includes forming a package component, the package component comprising an integrated circuit die, attaching the package component to a package substrate; placing a heat spreader over the package component and the package substrate to form an integrated circuit package, wherein a height of the integrated circuit package is in a range from 2.5 mm to 6 mm, and performing a first automatic optical inspection (AOI) process on the integrated circuit package using an AOI apparatus to determine if the orientation and alignment of the heat spreader with regards to the package substrate is within specification, wherein the AOI apparatus comprises a lens that has a maximum depth of field that is greater than the height of the integrated circuit package, and wherein during the first AOI process the depth of field encompasses an entirety of the height of the integrated circuit package.
