| titleOfInvention | Copper foil surface treatment method |
| abstract | [PROBLEMS] To develop a uniform and high-adhesion surface roughening method by an easy method without using toxic elements such as arsenic, selenium, and tellurium. SOLUTION: After the pickling step, at least one surface of the copper foil is activated by a positive / negative alternating pulse electrolysis or an activation processing step by performing an alternating current electrolysis in a sulfuric acid acid bath containing 1 ppm to 1000 ppm of chloride ions. , Fine roughening, followed by sulfuric acid, roughening of copper projections by performing cathodic electrolysis near or above the limiting current density in a copper sulfate bath, and further forming a coating layer by copper plating to form a copper foil Surface roughening, Then, a surface treatment method for the copper foil characterized by performing a rust prevention treatment.If necessary, a sulfur-containing organic compound is added in an amount of 0.001 to 0.5 mol / l between the pickling step and the activation treatment step. The organic compound containing sulfur, or treated with an aqueous solution containing sulfur, may be included in the bath of the pickling step. Furthermore, the positive and negative alternating pulse electrolysis time is appropriately set to 0.2 to 200 ms per cycle, and after the surface is roughened, a rust preventive treatment such as a chromate treatment and / or an organic rust preventive treatment is performed as necessary. |
