    Abstract: A printed circuit board includes a group of pads suitable to be soldered to a respective group of solder-balls of a device. Each pad of the group has a crack initiation point on its perimeter at a location where cracks in a solder-ball are anticipated to start after that solder-ball is soldered to that pad. For a pad of that group having a microvia located therein, a center of that microvia is located farther than a center of that pad from its crack initiation point. For a pad of that group having a trace merging along a portion of its perimeter, that portion does not include a vicinity of that crack initiation point.

  • Patent number: 8082172
    Abstract: Embodiments of the invention provide a comprehensive, automated system and method for evaluating the performance of individuals or entities employed by an organization, particularly useful in peer-profiling physician performance in multi-facility environments. Embodiments of the invention can dynamically compose a virtual peer or group of peers and perform peer-profiling on each individual or group of individuals to be evaluated. For example, a composite physician may be generated from system-wide and/or state-wide healthcare data as a benchmark against which a particular physician is profiled according to industry-standard measurements. The composite physician would have equivalent or similar job function(s) as well as patient population. The composite physician enables a comprehensive “apple to apple” comparison with the particular physician, giving meaning to and facilitating the usefulness of performance evaluation results.
