  • Method for testing multi-chip packages
    Patent number: 6728653
    Abstract: A specialized computer program is utilized to operate apparatus for testing internal components of an integrated circuit package. A Peltier-junction module is controlled so as to ramp-up and ramp-down the temperature of an integrated circuit package while reading out and plotting the power-bus-ground resistance of the package during the up-ramp and down-ramp cycles. The computer screen then indicates a characteristic graph for a properly working package and erratic graph for a package having a short circuit or open circuit components.
