  • Detaching a die from an adhesive tape by air ejection
    Patent number: 11764098
    Abstract: When picking a die from an adhesive tape, a collet of a pick arm is positioned at a distance over the die, the die being mounted on a first surface of the adhesive tape. A flow of air is then generated onto a second surface of the adhesive surface opposite to the first surface for blowing the adhesive tape to displace the die towards a die-holding surface of the collet. Thereafter, the die is retained on the die-holding surface of the collet while the adhesive tape separates from the die.
