AI Technical Summary
Existing aluminum foil patterning methods suffer from limitations in precision, insufficient process compatibility, and a trade-off between cost and efficiency, making it difficult to meet the demands for high precision and miniaturization.
Using LDI printing technology, patterned aluminum foil is prepared through steps such as UV curing of graphic ink, LDI exposure, and chemical copper plating, improving the accuracy to ±3μm, adhesion, and corrosion resistance, making it suitable for automated mass production.
It has achieved the preparation of high-precision patterned aluminum foil with an edge accuracy of no more than ±3μm, an adhesion of ≥5N/cm, and a salt spray corrosion resistance time of ≥48h. It is suitable for flexible electronic circuits, lithium battery tabs, or radio frequency antennas, improving production efficiency and product qualification rate.
