Claim:
1. A thermocompression bonding system for bonding semiconductor elements, the thermocompression bonding system comprising: a bond head assembly including a heater for heating a semiconductor element to be bonded, the bond head assembly including a fluid path configured to receive a cooling fluid during a cooling phase of a bonding cycle of the thermocompression bonding system; a pressurized cooling fluid source; a booster pump for receiving a pressurized cooling fluid from the pressurized cooling fluid source, and for increasing a pressure of the received pressurized cooling fluid; a pressurized fluid reservoir for receiving pressurized cooling fluid from the booster pump; and a control valve for controlling a supply of pressurized cooling fluid from the pressurized fluid reservoir to the fluid path to be different during different stages of the cooling phase of the bonding cycle.
