  • Patent number: 11428735
    Abstract: A system for monitoring and controlling an IC testing machine includes a vibration sensor, a sensor interface, and a processor coupled to the sensor interface. The vibration sensor is in mechanical communication with an IC testing machine to develop an electrical vibration signal representing mechanical vibrations generated by the operation of the IC testing machine. The sensor interface processes the vibration signal to develop vibration data that can be processed by the processor to determine whether the vibration data is indicative of an operational anomaly and, if so, to generate a machine control signal to correct an operation of the IC testing machine. Multiple vibration sensors can be used to increase the amount of vibration data available for analysis.

    Abstract: Wafer-level (chip-scale) package semiconductor devices are described that have bump assemblies configured to maintain standoff (bump) height. In an implementation, the wafer-level chip-scale package devices include an integrated circuit chip having an array of bump assemblies disposed over the integrated circuit chip. The array of bump assemblies comprises a plurality of first bump assemblies that include solder bumps composed at least substantially of a solder composition (i.e., do not include a core). The array further includes at least one second bump assembly including a solder bump having a core configured to maintain standoff height of the wafer-level package device.

  • Patent number: 9583425
    Abstract: A wafer level package includes a wafer, a lead disposed of the wafer for connecting the wafer to an electrical circuit, and a core disposed of the lead. In some embodiments, the lead disposed of the wafer is a copper pillar, and the core is plated onto the copper pillar. In some embodiments, the core is polymer screen-plated onto the lead. In some embodiments, the core extends between at least approximately thirty-five micrometers (35 ?m) and fifty micrometers (50 ?m) from the lead. In some embodiments, the core covers between at least approximately one-third (?) and one-half (½) of the surface area of the lead. In some embodiments, the core comprises a stud-shape extending from the lead. In some embodiments, the core extends perpendicularly across the lead. In some embodiments, the core extends longitudinally along the lead. Further, a portion of the core can extend perpendicularly from a longitudinal core.
