Description

Technical Field

[0001] The present application relates to the field of pulse electroplating, and in particular to a pulse electroplating solution addition technology, and specifically to a pulse electroplating solution quantitative addition device and addition method. Background Art

[0002] In the process of pulse plating, in order to achieve the ideal plating effect, it is generally necessary to add a pulse plating solution composed of different types of additives (such as brighteners, leveling agents, etc.). Different additives can have different effects on improving the quality of the coating, such as improving surface finish, enhancing conductivity or increasing hardness. However, the characteristics of different additives (such as density, viscosity, etc.) vary greatly, so it is necessary to accurately control their addition amount. At present, the addition of pulse plating solution is generally to connect multiple pumps in parallel to the same pipeline, and each pump adds a specific additive through a separate pipeline. This design allows different additives to be added simultaneously or one by one according to specific needs to meet the process requirements under different current intensities. Due to the different densities of different additives, the speed at which each pump delivers the additive varies greatly, making it difficult to ensure a consistent addition speed, which can easily lead to problems such as uneven mixing of additives; and different liquids have different corrosiveness and wear on the pump itself. As time goes by, the performance of the pump will decline, affecting the speed and accuracy of adding pulse plating solution, and ultimately affecting the quality of pulse plating.
