    摘要: The specification describes a flexible membrane test apparatus and test method for high-speed IC chips. The method and apparatus rely on locating the reference components of the test circuit very close to the contact pads of the IC chip under test. This is achieved in one embodiment by locating those components adjacent to the flexible membrane. In another embodiment, the reference components may be attached to the membrane itself, so the length of the runners connecting the contact points of the tester and the critical reference components is optimally reduced. In yet a further embodiment, the entire test circuit, in the form of an IC test chip, is located on the membrane.

    摘要: The quality of soldering produced on devices such as printed circuit boards and multichip modules is significantly improved through use of a specific size distribution of solder particles. In particular, the solder includes a vehicle and solder particles of specific size. In general, an appropriate distribution of both large and small particles should be employed. Through this expedient short circuits and soldering defects in fine line devices are reduced.

    摘要: Balun transformers are described wherein multiple transformer loops are implemented in a stacked design with the primary and secondary loops overlying one another. By aligning the loops in a vertical direction, instead of offsetting the loops, the area of the device is reduced. Multiple transformer loops are nested on each level, and the transformer loops on a given level are connected together using a crossover located on a different level.

    摘要: An RF/IPD package with improved thermal management is described. The IPD substrate is attached to a system substrate with a thin RF chip mounted in the standoff between the IPD substrate and the system substrate. RF interconnections are made between the top of the RF chip and the bottom of the IPD substrate. Heat sinking is provided by bonding a heat sink layer on the RF chip to a heat sink layer on the system substrate. The heat sink may also serve as a ground plane connection. Combinations of other types of integrated devices may be fabricated using this approach.
