Abstract:
An integrated circuit package substrate (ICPS) system includes a die including a first array of connectors and a substrate including a second array of connectors that is configured to be thermocompression bonded to the first array of connectors at a bonding temperature that is above a solder melting temperature. The first die is bonded to the substrate such that the first die is asymmetric with respect to a substrate center, and the second array of connectors is adjusted, at an alignment temperature that is below the solder melting temperature, for thermal expansion to the bonding temperature with respect to a reference point that is not a first die center.
