A method for deprotecting alkyl arylamine ethers to produce hydroxyl arylamine compounds by reacting the alkyl arylamine ether with a thiolate reagent. A collar is disposed around the ball to provide support, and prevent solder interaction in the undercut areas of the UBM. Moreover, conventional wet cleaning agents such as hydrofluoric acid and ammonium fluoride may be used with the present invention to perform substrate pre-treatments prior to precision drying and cleaning treatments described herein. A rudder assembly and a deflector structure are secured to an exterior of the nozzle and function to determine the craft’s direction of travel.
