Abstract
Aspects of the present disclosure are directed to methods and apparatuses involving a chip carrier having openings therein that align integrated circuit (IC) chips relative to an alignment feature. The IC chips and carrier are tested, such as by final testing the affixed IC chips after manufacture, and further testing after subjecting the affixed IC chips to one or more stress conditions. A test probe is aligned to one or more contacts on each chip based on the location of an alignment feature of the carrier relative to the opening in which the IC chip being tested is located. Responsiveness of the IC chip, before and after application of the one or more stress conditions, can be assessed by probing the IC chip via the aligned test probe, and assessing electrical signals received over the test probe.
