The objective of this study was to investigate the significant characteristics in the sprays of industrial etching nozzles for the sake of process design. The experiment was carried out with different spray pressures and industrial nozzles in the spray etching. Characteristics of the spray, such as the axial velocity and the Sauter mean diameter (SMD), were obtained through the Phase-Doppler Anemometer (PDA). The impact force was calculated through the spray characteristics. It was found that liquid with higher spray pressure resulted in a smaller SMD, higher droplet velocity, and greater impact force. The depth of etching was increased in the case of higher spray pressure. When the spray angle oscillated between $20^{circ}$ and $-20^{circ}$, the effect of etching remained constant. The relationships between the spray characteristics and the etching characteristics were analyzed. The depth of etching had significant, positive correlations with the axial velocity and the impact force. Four liquids of different kinematic viscosities were used to reveal the effects of the kinematic viscosity on the spray characteristics. The results indicated that a lower viscosity of the spray yielded a higher etching rate than a higher viscosity of the liquid. The results clearly show that the characteristics of the spray etching are strongly related to the spray characteristics with the spray conditions.
