Abstract
A method of bonding a die comprising solder bumps to a substrate comprising bond pads, the method comprising the steps of heating the die from a first temperature to a second temperature, wherein the first temperature is below the melting point of the solder bumps, and the second temperature is above the melting point of the solder bumps; moving the die relative to the substrate to a first height, whereat the solder bumps contact the bond pads; moving the die further away from the substrate to a second height, while maintaining contact between the solder bumps and bond pads; and thereafter cooling the die from the second temperature to a third temperature to allow the solder bumps to solidify so as to bond the die to the substrate.
