Abstract:
1. Method for detaching a die from an adhesive tape on which the die is mounted, comprising the steps of: supporting with a support surface inner and outer portions of a first side of the die which is in contact with the adhesive tape; contacting the inner and outer portions of a second side of the die opposite to the first side with a collet; withdrawing support from the outer portion of the die such that the outer portion of the second side of the die bends away from contact with the collet while the support surface only supports the inner portion of the die; applying vacuum suction from the collet to attract the outer portion of the die towards the collet and monitoring the vacuum suction pressure until a threshold pressure is reached indicating that the outer portion of the die is contacting the collet; and thereafter lifting the collet while the collet is holding the die with vacuum suction to completely separate the die from the adhesive tape.
