Abstract:
A method of testing a bumped device having an array of conductive bumps, comprising:providing a first structure; providing a second structure coupled to the first structure, the second structure having a single opening, the second structure being moveable with respect to the first structure between a first position proximate the first structure and a second position spaced apart from the first structure, and a plurality of contact elements projecting at least partially through the first structure and into the single opening; positioning the bumped device in contact with the second structure; aligning the array of conductive bumps with the plurality of contact elements; applying an engaging force to the second structure to move the second structure toward the first position, thereby moving the contact elements into the single opening and bringing the array of conductive bumps into contact with the plurality of contact elements; transmitting test signals to the bumped device through at least some of the contact elements; and applying a disengaging force to the second structure to move the second structure toward the second position, the second structure disengaging the array of conductive bumps from the plurality of contact elements.
