    摘要: Improved methods, systems, and apparatuses are disclosed for testing LGA devices. One example embodiment include vertical routing of test nest assembly cooling lines in order to minimize the test nest footprint and increase available test sites on a single test card. Another example embodiment includes isolating and adjusting external loads and moments into the heatsink/cold plate, wherein these loads and moments involve controlling the centroid to restore more ideal thermal performance of the heatsink/chip interface. Still another example embodiment includes a nest architecture facilitating easy and low-cost replacement of LGA sockets. Finally, another example embodiment includes efficient condensation control of test nest assembly parts by using dry-air exhaust.

    摘要: An innovative chip testing system and method includes controlling temperature and condensation during testing. Coarse temperature is controlled by providing a desired fluid flow rate and fluid temperature to a cold plate. Fine temperature control is provided by a feedback loop which controls the power dissipation of cartridge heaters installed within the cold plate. Condensation control is provided by insulating various components of the system, manipulation of dry compressed air in enclosures to reduce surface dew point temperatures, usage of cartridge heaters in a card backside stiffener plate, and by providing a heatsink assembly which prevents condensation on the insulation.
