FEATURES

    Stencils
    Analysis of Stencil Tensioning (Elasticity)
    Foil tension variations may create distortion and unpredictable print deposition. An explanation of methods for measuring the tension-elasticity across the foil, and how a novel technology can perform fast, real-time mapping of stencil characteristics.
    by Ricky Bennett, Ph.D., and Richard Lieske

    Reliability
    The Role of Failure-Oriented-Accelerated-Testing for Field Functional IC Packages
    Devices are known to pass qualification testing, then fail in the field. Does that suggest the test specifications are inadequate?
    by Ephraim Suhir, Ph.D.

    Defects Database
    Trim Those Whiskers
    The speed of dendrite formation depends on the material, voltage applied and separation distance between terminations. This is the case in a normal failure but is also exaggerated by the level of surface moisture.
    by Dr. Chris Hunt
