Abstract: During detachment of a die from an adhesive tape, the inner and outer portions of a first side of the die which is in contact with the adhesive tape is supported with a support surface. A collet contacts the inner and outer portions of a second side of the die opposite to the first side. Support is withdrawn from the outer portion of the die such that the outer portion of the second side of the die bends away from the collet while the support surface only supports the inner portion of the die. Vacuum suction from the collet is applied to attract the outer portion of the die towards the collet and the vacuum suction pressure is monitored until a threshold pressure is reached indicating that the outer portion of the die is contacting the collet. Thereafter, the collet is lifted while holding the die with vacuum suction to completely separate the die from the adhesive tape.
