Index / Projects / Laser Macro-perforation on copper foil
Laser Macro-Perforation on copper foil is widely used in battery current collectors for venting and fluid channels, roll-to-roll alignment, structural weight reduction, thermal management, and welding positioning.
Laser perforation offers clean edges, no tooling, and flexible patterns, enabling high-precision holes from 0.5 mm to over 3 mm for advanced applications in batteries, circuits, and flexible electronics.
