Effect of Time and Temperature on the Quality of Stator Connectivity in the Dip Soldering Process of Electric Toothbrush Products

Abstract

In the development of electronic component production, the mechanical quality of electronic component assembly is an important part to estimate the overall quality of electronic equipment, especially for electric toothbrush products. The performance, dependability and durability of an electric toothbrush are directly affected by the connectivity of the stator, making it a critical component in the manufacturing process. Solder dipping is an important step in guaranteeing good connectivity. The process involves dipping the metal contacts into solder tin to create a strong electrical connection. The temperature and duration of the dipping process are crucial factors that significantly affect the quality of the final product. Lack of solder penetration or component damage due to overheating can result from inappropriate temperatures or time periods. To determine the ideal parameters, tests were conducted using anova methodology on several stator samples. The optimal parameter combination was found at 380 °C with a dipping duration of 4 seconds, which provided complete solder penetration, strong mechanical bonding, and no observable thermal damage to the stator components. Lower temperatures tended to cause incomplete soldering, while higher temperatures or longer dipping times increased the risk of overheating and deformation. The findings from this study can be used as a guide by the electronics sector to optimize soldering procedures and improve the caliber and longevity of its products.
