Description

technical field [0001] The invention relates to the technical field of electrolytic copper foil experiments, in particular to a system for experimental research on electrolytic copper foils and a method for using the same. Background technique [0002] Electrolytic copper foil is an important conductor raw material for the manufacture of copper clad laminates (CCL), printed circuit boards (PCB), flexible circuit boards (FPC) and lithium-ion batteries (LIB), and is widely used in electronics, communications, computers and other fields. With the rapid development of electronic technology, the market demand for high-performance electrolytic copper foil is increasing. In the production process of electrolytic copper foil, the solution and electrolytic process parameters play a very important role. However, in actual production, due to various conditions, the required electrolytic copper foil cannot be prepared truthfully. Therefore, in order to avoid the trial production process...

AI Technical Summary

Problems solved by technology

As far as static electroplating is concerned, the concentration polarization of the cathode is serious, which is likely to cause loose electrolytic copper foil deposition structure, especially high-current deposition is more likely to produce copper powder; at the same time, the electrolyte of electrolytic copper foil is continuously diluted with the electroplating time. Static electroplating cannot maintain the stability of the electrolyte composition; moreover, the electrolytic copper foil is produced stably within the set temperature range, and the constant temperature needs to be considered during the test

Therefore, the current test equipment alone cannot fully meet the needs of actual production. It is urgent to design an electrolytic cell device that can not only eliminate the concentration polarization problem, but also supplement the electrolyte components and keep the temperature constant.
