From electrochemical kinetics to evaluate the through hole thickening

Acidic and alkaline [5], [6], [7] copper plating processes have been both proposed for the through hole thickening and blind via filling. For the widely used acidic copper sulfate process, three additives such as suppressor [8], [9] (polyether, such as polyethylene glycol, PEG), accelerator [10], [11] (sulfonate-terminated alkyl-disulfide, such as bis-(3-sulfopropyl) disulfide, …

Thickener optimizer

Thickening is, by nature, a slow process with multiple variables influencing process performance. For example, when the feed mass flow and its properties change, timely adjustments are needed to maintain a stable output. This requires a good understanding of process dynamics and overall process behavior.

How a Thickener Works

For good dewatering, you always need a pressure filter after thickening. The Dorr traction thickener is the type most frequently used for heavy- duty work with large tonnages. The machine is so called because the thickening mechanism is driven by means of a traction wheel which travels around the periphery of the tank on a rail.
