What equipment is best for laser cutting thin films like PET/PI/FPC?

What equipment is good for Thin film laser cutting for materials like PET/PI/FPC? A thin film is a thin, soft, transparent film. Made of plastic, adhesive, rubber or other materials. The scientific explanation of a thin film is a two-dimensional material composed of atoms, molecules or ions deposited on the surface of a substrate. For example: optical films, composite films, superconducting films, polyester films, nylon films, plastic films, etc. Thin films are widely used in electronics, machinery, printing and other industries. Thin film materials refer to metal or organic layers with a thickness ranging from a single atom to several millimeters. Electronic semiconductor functional devices and optical coatings are the main applications of film technology. Common films include polyester, polyethylene, polyethylene, polypropylene and polypropylene.

In order to improve the material's absorption of laser energy, the cutting surface is vertical and smooth, the heat-affected area is small, and curling is prevented. Precision and low-heat-consuming laser equipment is required to process the above materials to solve the shortcomings of jagged, yellowing, blackening, and severe curling. The editor of Laisai Laser recommends several thin film laser cutting equipment:

1. Ordinary high-speedCO2 laser die-cutting machine, there is a slight melting phenomenon on the relative cutting edge.

2. Nanosecond UV laser cutting can be used, and the cutting edge is smooth, burr-free, and slightly black.

3. If the product cutting requirements are high and the budget is sufficient, picosecond UV or femtosecond and green laser cutting machines can be used. It can effectively solve the problems of speed, edge burrs, black carbonization, curling, etc. The cross section is smooth and beautiful.
