Using a laser to cut copper foil, copper foil is also one of the commonly used components in the electronics industry. The electrolyte is a negative electrolyte, which is deposited as a layer on the substrate of the circuit board and acts as a conductor of the circuit board. Copper foil is a very thin copper product. Copper, like paper, is also micrometers thick. Usually 5um-135um, the thinner and wider, the harder it is to make. Simply put, pressing copper into a very thin sheet is copper foil.


Copper foil laser cutting


UV laser cutting machines are widely used in copper foil cutting applications. The difficulty of copper foil cutting is that the cutting edge is not carbonized, there is no burr, and the copper foil is not deformed, which realizes the processing method of roll-to-roll. Ordinary laser cutting machines have great thermal influence, different directions of use, and lower precision than UV laser cutting machines. When the edge is carbonized, the thermal effect of the edge is the warping and deformation of the copper foil.


The advantage of copper foil laser cutting is that the laser is a cold source, has little thermal impact on the processing material, small processing gap, smooth processing edge, no burr, especially suitable for cutting copper foil, ultra-thin metal alloy and other ultra-thin metal materials. In addition, it has also been widely used in the field of conductive metal films. The UV laser cutting machine adopts mirror scanning, vacuum adsorption at the bottom, and cold source to reduce the influence of heat source to achieve perfect copper foil cutting, and is also suitable for ultra-fine metal cutting.
