Copper foil laser cutting (ultra-thin metal film laser cutting application)

Use Laser Cutting 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 serves as a conductor of the circuit board. Copper foil is a very thin copper product. Copper, like paper, is also micron thick. Usually 5um-135um, the thinner and wider it is, the more difficult it is to make. In short, copper foil is copper pressed into a very thin sheet.

Ultraviolet laser cutting machine has been widely used in copper foil cutting applications. The difficulty of copper foil cutting is that the cutting edge is not carbonized, there are no burrs, and the copper foil is not deformed, realizing the roll-to-roll processing method. Ordinary laser cutting machines have a large thermal impact, different use directions, and lower precision than ultraviolet 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, which has little thermal impact on the processed material, small processing gap, smooth processing edge and no burrs. It is especially suitable for cutting ultra-thin metal materials such as copper foil and ultra-thin metal alloys. In addition, it has also been widely used in the field of conductive metal films. The UV laser cutting machine adopts mirror scanning, bottom vacuum adsorption, cold source to reduce the influence of heat source, and achieve perfect copper foil cutting. It is also suitable for ultra-fine metal cutting.
