Description

Technical Field

[0001] This utility model relates to the field of electrolytic clamp technology, specifically to an electrolytic clamp for copper foil. Background Technology

[0002] Copper foil is a thin, continuous metal foil deposited on the substrate layer of a circuit board using an anionic electrolytic material. As a conductor in the PCB, it easily adheres to the insulating layer, receives the printed protective layer, and forms the circuit pattern after etching. Copper foil has low surface oxygen properties, allowing it to adhere to various substrates such as metals and insulating materials. It has a wide operating temperature range and is mainly used for electromagnetic shielding and antistatic purposes. Placing conductive copper foil on the substrate surface, combined with the metal substrate, provides excellent conductivity and electromagnetic shielding.

[0003] Copper foil generally requires electroplating during production to increase its conductivity, corrosion resistance, and surface smoothness. Electroplating of copper foil typically uses electrolytic fixtures, but existing electrolytic fixtures are inconvenient to install quickly on fixed crossbars and are not convenient for secondary adjustment of the spacing after installation. Therefore, there is an urgent need for an electrolytic fixture for copper foil to overcome these shortcomings. Utility Model Content
