    • The specification describes an IC test apparatus having a test bed with sockets adapted to engage arrays of I/O solder balls/bumps on the IC chip. In one embodiment the sockets are provided with through holes to interconnect the solder bumps to the next board level with minimum electrical path length thereby reducing parasitic capacitive coupling. In another embodiment the sockets in the test bed are formed by intersecting V-grooves. If pairs of intersecting V-grooves are used, pyramid shaped features are produced at the bottom of each socket. Both the sharp edges formed by the intersecting V-grooves and the pyramid provide contact enhancement between the solder bumps and the test bed. The test bed can be made as a universal blank for a given solder bump pitch. The desired test circuit is formed at the next board level.
    • 本说明书描述了一种具有测试台的IC测试装置,其具有适于接合IC芯片上的I / O焊球/凸起阵列的插座。 在一个实施例中,插座设置有通孔,以将焊料凸块互连到具有最小电路长度的下一个电路板级,从而减少寄生电容耦合。 在另一个实施例中,试验台中的插座由V形槽相交形成。 如果使用成对的相交的V形槽,则在每个插座的底部产生金字塔形特征。 由相交的V形槽和金字塔形成的锐利边缘都提供焊料凸块和试验台之间的接触增强。 测试台可以作为给定焊料凸块间距的通用坯料。 所需的测试电路在下一个电路板级形成。

    • A reversible reaction sensor provides for detecting medical, biologic or explosive airborne compounds. The sensor may be formed in semiconductor material and is activated by radiation from sources to provide sensing of particular airborne compounds optically detectable by detectors, and reversed by other radiation from a source (or removal of activating radiation) to take away such airborne compounds from the sensor. The reversible reaction sensor device has a sensing material of one or more photo-chromic or photo-biologic compounds for a specific compound(s) or analytic(s) having receptor sites which bound molecularly to specific compound(s) or analytic(s) when present, in which sensing relies only on the response time to saturation for the sensing material as measured by an optical property of the sensing material when exposed to radiation. The sensing material is self cleaning by one or more of light of a specific wavelength, radio waves of a specific frequency, absence of said light illuminating said material, absence or presence of a magnetic field, which causes the receptor sites to close and the bound specific analytic are released and swept away by flow of air. The sensor may be in hermetically sealed and non-hermetic assemblies.
    • 可逆反应传感器用于检测医疗,生物或爆炸性空气传播的化合物。 传感器可以形成在半导体材料中并且通过来自辐射源的激光被激活,以提供对由检测器光学可检测的特定空气传播的化合物的感测,并且由来自源的其它辐射(或去除活化辐射)反转,以将这些空气传播的化合物从 传感器。 可逆反应传感器装置具有用于特定化合物或具有与特定化合物或分析物分子结合的受体位点的分析物的一种或多种光致变色或光生物化合物的感测材料, 当存在时,其中感测仅依赖于当暴露于辐射时由感测材料的光学性质测量的感测材料的响应时间达到饱和度。 感测材料通过一种或多种特定波长的光,特定频率的无线电波,不存在照射所述材料的所述光,不存在或存在磁场而导致受体部位闭合和束缚 特定的分析物被释放并被空气流扫除。 传感器可以是密封的和非密封的组件。
