    摘要: A method and system for identifying voids in solder balls in a ball-grid array (BGA) using an image of the BGA include localizing an image of a solder ball on the BGA image, the solder ball image having a radius and having multiple points each having an image intensity, and producing a void-free model image of the solder ball based on the radius of the solder ball image, the void-free model image having multiple points each having an image intensity. The method and system also include computing a difference between the image intensities of the points of the solder ball image and the image intensities of the points of the void-free model image to produce a residual image, and identifying a void using the residual image.

    摘要: Some embodiments of the present invention provide a system that characterizes a response of a component in a computer system to vibrations generated by the computer system. First, the system measures the response of the component to vibrations in a frequency range while the component is located outside of the computer system. The system also measures vibrations generated by the computer system in the frequency range during operation of the computer system, wherein the vibrations are measured at a location in the computer system which is configured to receive the component. The system then characterizes the response of the component to vibrations generated by the computer system based on the measured response of the component to vibrations in the frequency range and the measured vibrations in the frequency range at the location.

    摘要: A method for generating a service action for a computer system is described. During the method, a longevity index value for a packaging technology in the computer system is calculated using a longevity model and thermal and vibration telemetry data that is collected in the computer system. This longevity model may be based on accelerated failure testing of the packaging technology, field failures of the packaging technology in a group of computer systems that includes the computer system, and/or thermal and vibration telemetry data for the group of computer systems. Furthermore, using the longevity index value, the service action for the computer system is determined. Based on the longevity index value, remedial as action, e.g., repairs to the computer system, may be scheduled and performed.

    摘要: Some embodiments of the present invention provide a system that characterizes the performance of a disk drive at frequencies in a set of frequencies in a frequency range. First, the disk drive is vibrated at each frequency in the set of frequencies, one frequency at a time. During this process, a disk drive performance metric is monitored. Next, the performance of the disk drive is characterized by determining the parameter related to acceleration due to the vibrations for each frequency at which a disk drive performance metric degrades by a predetermined amount from a baseline.
