    Abstract: Apparatuses may include a device substrate including a microelectronic device and bond pads proximate to an active surface of the device substrate. A package substrate may be secured to the device substrate, the package substrate configured to route signals to and from the bond pads. A ball grid array may be supported on, and electrically connected to, the package substrate. Each ball positioned and configured to carry a high-bandwidth data signal or a high-frequency clock signal may be located laterally or longitudinally adjacent to no more than one other ball of the ball grid array configured to carry a high-bandwidth data signal or a high-frequency clock signal. Each ball positioned and configured to carry a high-bandwidth data signal may be located only diagonally adjacent to any other balls configured to carry a high-bandwidth data signal or a high-frequency clock signal.

    Abstract: Systems may include a central processing unit (CPU), a graphics processing unit (GPU), or a field programmable gate array (FPGA), or any combination thereof. At least one memory device may be connected to the CPU, the GPU, or the FPGA. The memory device(s) may include a device substrate including a microelectronic device and bond pads coupled with an active surface of the device substrate. A package substrate may be secured to the device substrate, the package substrate configured to route signals to and from the bond pads. A ball grid array may be supported on the package substrate. Each ball of the ball grid array positioned and configured to carry one of a high-bandwidth data signal or a high-frequency clock signal may be located only diagonally adjacent to any other balls of the ball grid array configured to carry another of a high-bandwidth data signal or a high-frequency clock signal.

    Abstract: Aspects of the present disclosure configure a processor to detect faults in a printed circuit board (PCB) solder mask using an optical waveguide. The processor directs an optical beam to an input of one or more optical waveguides embedded in a protective coating layer of a PCB, the protective coating layer being adjacent to one or more traces of the PCB. The processor measures a beam characteristic of the optical beam that is output by the one or more optical waveguides. The processor detects a disruption of the optical beam that is output by the one or more optical waveguides based on the beam characteristic. The processor detects a fault in the protective coating layer of the PCB based on detecting the disruption of the optical beam that is output by the one or more optical waveguides.

    Abstract: Semiconductor devices, such as memory devices, and associated systems and methods, are disclosed herein. A representative semiconductor device comprises a substrate including a plurality of conductive contacts and a mask material having a surface. The mask material includes (a) a first recess formed in the surface having a first depth and (b) a second recess formed in the surface having a second depth greater than the first depth. An exposed portion of each of the conductive contacts is exposed from the mask material in the second recess. The semiconductor device further comprises a semiconductor die including a lower surface having bond pads, and the lower surface is positioned in the first recess. The semiconductor device further comprises a plurality of conductive features electrically coupling individual ones of the bond pads to corresponding ones of the exposed portions of the conductive contacts.
