<p>An IC handler inverts an IC in a single motion by first gripping the IC with two fingers attached to an arm and then flipping the IC over by rotating the arm in a one-hundred eighty degree arc. The fingers maintain contact with the IC during the entire one-hundred eighty degree motion. The fingers grip the IC from the sides so that they can drop the IC onto a carrier after flipping the IC. After flipping, the IC is lowered onto the carrier by an air cylinder until two precising pins engage the carrier. The IC can thus be delivered to a testing device with its electrical contacts facing up.</p> |
