This paper is mainly aimed at the study on the effect of the copper lead frame oxidation on the packaging industry. As the copper lead frame after baking in the high temperature will result in the falling off of the pins in soldering operation in the front-end manufacturing process of the semiconductor industry, this abnormity is positive correlation with the oxidation of the copper lead frame. In addition, the oxidation easily leads to the instability of the metal and quality control. Therefore, this study improves the baking environment of the high temperature furnace chamber with low oxygen content, effectively control the nitrogen flow, baking temperature, baking time, etc., to reduce the oxide on the copper conductive frame, and meet the criteria of experimental water droplets angle. Water droplets angle measurement is taken as an index for the eutectic plates and surface cleaning, and the experiment output response is analyzed with the smaller-the-better characteristics, so as to obtain the effects of various factors from the experiment on the copper lead frame.
