The objective of this work was to simulate lead frame etching characteristics to optimize the etching process. Characteristics such as the etching factor and uniformity were investigated for different actual operating conditions, including pressure, distance from the nozzle tip, pipe pitch, and feed speed. The correlation between the etching and spray characteristics was analyzed to develop the etching model. Spray characteristics obtained from an experiment using a phase Doppler anemometer system were then simulated using a Monte-Carlo technique. The etching process model was coded in the Java language. The spray and etching characteristics were correlated with each other and simulated results agreed well with the measured data for a lead frame etching process. The optimal operating parameters under various conditions were successfully determined.
