A die bonding method with corner or side contact without impact force includes the steps: picking up a die by a die bonding device, wherein a surface of the die has no solder and bump; moving the die to one side of a die placement area of a substrate, wherein the substrate has no solder and bump; blowing one corner or one side of the die a positive pressure from the die bonding device to bend the corner/side to contact the die placement area; forming a bonding wave after the corner/side of the die contacting the die placement area, and spreading the bonding wave from the corner/side to opposite corner/side of the die, and separating the die from the die bonding device gradually and bonding the die on the die placement area; and bonding the die on the die placement area completely.
