Method and system for comprehensive testing of network connections
InactiveUS20070041554A1Special service for subscribersSupervisory/monitoring/testing arrangementsData setNetwork connection
The present invention is an system and method for comprehensively testing a customer connection to a communications network. A customer is identified from information obtained at a customer interface. A test can be performed on the customer connection. A typical test compares two datasets related to the customer connection to determine a state of the customer connection. The first and second dataset can include historical data. A parameter in the first dataset obtained from a network element can be compared to a parameter in a second dataset obtained from a customer database. The comparison can be made in light of changes recorded in a provisioning database. Relevant network data can be obtained from customer premises equipment (CPE). The customer can be notified of a network issue proactively or upon customer inquiry.

A system in package (SIP) is fabricated on a sheet of copper foil. An interconnection circuit is fabricated on the foil using copper conductors and a dual damascene structure for each conductive layer. The preferred dielectric material is an amorphous fluorinated polymer called Cytop. Input / output traces of the interconnection circuit terminate in wells filled with solder. Chips are bumped and direct attached by inserting the bumps into the wells. The preferred bumps are gold stud bumps, and the preferred wells contain solder paste to a depth of approximately 15 microns. Imprinting is the preferred method for patterning; it enables 6-micron wide traces, 6-micron diameter vias, and a cost per well of around 0.02 cents. Stripline structures are described for a 4-layer stackup that can support operating frequencies of at least 10 GHz. New methods are proposed for testing the completed assembly and for rework of any chips that prove defective. After the assembly is fully tested and reworked in sheet form the copper foil is folded to form a stacked die package or system in package. 5-high and 9-high stacks are illustrated. The copper foil provides a low impedance thermal path for cooling every chip in the SIP.
