Abstract: Techniques and mechanisms for determining a level of degradation of flexible circuitry. In an embodiment, a flexible substrate has disposed therein first circuitry and one or more components coupled thereto, the one or more components to monitor a physical property of the first circuitry. Further disposed in or on the flexible substrate are memory resources to store predefined reference information which corresponds amounts of the physical property each with a different respective level of degradation. Evaluation logic accesses the reference information to determine, based on a detected amount of the physical property, a level of degradation of second circuitry. In another embodiment, the second circuitry is more flexible, as compared to the first circuitry.

Abstract: A stiffener, an IC package and methods of fabrication of an IC package including a removable stiffener are shown. A removable stiffener for use with an integrated circuit (IC), including a plurality of adhesive portions disposed between a surface of the stiffener and a surface of a substrate of the IC is shown. Such a removable stiffener including at least one removal tab is shown. An IC package including a removable stiffener including a plurality of adhesive portions disposed between a surface of the stiffener and a surface of a substrate of the IC is shown. Methods of fabrication of an IC package including a removable stiffener are shown.

Abstract: Embodiments are generally directed to a lateral expansion apparatus for mechanical testing of stretchable electronics. An embodiment of a system includes a compressible cylinder to apply mechanical forces to a stretchable electronics device by the compression and release of the compressible cylinder; a compression unit to compress to the compressible cylinder, wherein the compression unit is to apply a compression force in a direction along an axis of the compressible cylinder to generate lateral expansion of the compressible cylinder; and a testing logic to control compression and release of the compressible cylinder.
