Abstract
PURPOSE:To release a defective pellet from an electron sheet easily, by pushing up a part close to the edge of the defective pellet, chucking the rear surface of the detective pellet by means of a sucking nozzle, and lifting up the pellet. CONSTITUTION:An upper end surface 1a of a pushing-up pin 1 is cut in a slant shape. The slanted upper end surface 1a of said pushing-up pin 1 is pushed to the rear surface of a defective pellet 3 through an electron sheet 4. The defective pellet 3 is pushed up in a slant attitude with said pushing-up pin 1. An inserting space S for a sucking nozzle 2 is secured between a part of a rear surface 3a of the defective pellet 3 and the electron sheet 4. Then, the sucking nozzle 2 is inserted into the inserting space S between the rear surface 3a of the defective pellet 3 and the electron sheet 4. A part of the rear surface 3a of the defective pellet 3 is chucked with said sucking nozzle 2. With the sucking nozzle 2 being attached to a part of the rear surface 3a of the defective pellet 3, the sucking nozzle 2 is lifted up to the slant upper part. Thus, the defective pellet 3 is released and removed from the electron sheet 4.
