Abstract

The present invention may be characterized as an improved integrated circuit die testing system which includes a number of components which cooperate together. An integrated circuit carrier is provided for holding the integrated circuit die. Attached to the integrated circuit carrier is a chip site. Proximate to this chip site exists a plurality of contact pads. These contact pads are electrically coupled to a plurality of test points. Also provided is an integrated circuit die. Finally, a pattern of electrically conductive paste is provided. This electrically conductive paste electrically couples the integrated circuit die and the contact pads thereby allowing the integrated circuit die to be tested from the test points.
