摘要： An apparatus for detecting failures in electrical connections between an integrated circuit package substrate and a circuit board. The substrate has substrate electrical contacts that are electrically connected one to another in first sets in a first region of the substrate. The circuit board has circuit board electrical contacts that are electrically connected one to another in second sets in a second region of the circuit board. The substrate electrical contacts align with and make electrical contact with the circuit board electrical contacts. The first region of the substrate aligns with the second region of the circuit board when the substrate electrical contacts make electrical contact with the circuit board electrical contacts. The first sets of substrate electrical contacts form chains of electrical contacts with the second sets of circuit board electrical contacts. The chains of electrical contacts loop back and forth electrically between the substrate and the circuit board.

摘要： A tester head from a tester is used to mount a probe card. A DUT/load board has a socket which is configured to hold a substrate. Probe pins from the probe card make contact with bump pads on the substrate. Signal wires from the DUT/load board are fed to the tester, and the tester is connected to a DSO with a fast rise time signal head. During testing, a signal is launched using the DSO into a coaxial cable which is connected to the test head. The launched signal and the reflected signal are captured back by the DSO, and then fed into the tester. Using this data, post processing software is used to obtain the interconnect impedance versus time for the device (i.e., package) under test. The method and apparatus can be used in connection with both Flip Chip and Wire bonded products.

The method includes patterning a plurality of signal traces on a multilayer substrate, and patterning a plurality of guard traces on the multilayer substrate, that are interspersed alternately among the signal traces to provide noise shielding between the signal traces. In a further embodiment, the traces are patterned on the substrate with a width that is adjusted at different locations based on the presence the guard traces to enable the package to meet a particular impedance requirement.

摘要： A stiffener for reinforcing a package integrated circuit. The stiffener includes a rigid planar element having a first surface for bonding to a package substrate. The rigid planar element forms a major interior aperture for receiving and surrounding an integrated circuit on all sides of the integrated circuit. The rigid planar element also forms a minor interior aperture for receiving and surrounding a secondary circuit structure on at least three sides of the secondary circuit structure. In this manner, the stiffener provides structural support to the integrated circuit package, which reduces and preferably eliminates twisting and warping of the substrate package as it heats and is subjected to other stresses. Because the major interior apertures does not need to be large enough to fit both the monolithic integrated circuit and the secondary circuit structure, there is more stiffener material available to provide structural support than there would be if the major interior aperture was large enough to fit both the monolithic integrated circuit and the secondary circuit structure.
