Copper foil is also one of the common components in electronic applications. It is a cathodic electrolytic material and a thin, continuous layer of metal foil deposited on the base layer of the circuit board. It serves as the conductor of the circuit board. Copper foil is a very thin copper product. The thickness of paper-like copper is expressed in microns. Generally between 5um and 135um, the thinner and wider it is, the harder it is to produce. Simply put, copper is pressed into very thin sheets, which is copper foil.
Advantages and Features of UV Laser Cutting Copper Foil
In the cutting application of copper foil, UV laser cutting machines are more common and widely used. The difficulty of cutting copper foil lies in the fact that the cutting edges are free of carbonization and burrs, and the copper foil will not be deformed, allowing roll-to-roll processing to be achieved. General laser cutting machines have a greater thermal impact, and their application directions are different. The accuracy is lower than that of UV laser cutting machines. In the eyes of edge carbonization, the thermal impact of the edges will cause the copper foil to warp and deform.
What to use UV laser cutting
The advantage of UV laser cutting machine is that the laser it uses is a cold light source, which has little thermal impact on the processed materials, small processing gaps, smooth processing edges and no burrs. It is especially suitable for cutting ultra-thin metal materials, such as copper foil, ultra-thin metal Alloys etc. In addition, it is also widely used in the field of conductive metal films. The processing mode of the UV laser cutting machine adopts the galvanometer scanning method, the bottom uses vacuum adsorption, and the cold light source reduces the thermal impact to achieve perfect cutting of copper foil. It is also suitable for ultra-thin metal cutting.
When applying UV laser cutting machines to cutting copper foil, we consider not only equipment hardware, but also comprehensive strength assessments such as process experience and process capabilities. To cut copper foil well, laser equipment suppliers need to break through in UV laser cutting machines. Innovation.
