PI film is also known as polyimide film. It is no exaggeration to say that it is the best film insulation material in the world. It is widely used in space technology, electrical insulation, FPC (flexible printed circuit board), PTC electrothermal film, tab (pressure sensitive tape substrate), aerospace, aviation, computer, electromagnetic wire, transformer, audio, mobile phone, computer, smelting, mining, electronic component industry, automobile, transportation In the electronic and electrical industries such as the atomic energy industry, especially in recent years, the process reform of the mobile phone industry has used flexible OLED screens to replace the traditional mobile phone screens, which has led to a great increase in the demand for flexible OLED screens. As the most suitable flexible display material, PI film has risen with the tide, and the market demand has soared.
As a polymer material, PI film has high technological barriers and great processing difficulties. In the face of increasingly refined scene applications, the traditional PI film cutting methods can not meet people's needs. In order to balance the contradiction between the increase in demand and the difficulty in cutting, many manufacturers have introduced laser technology and used high-precision PI film laser cutting machines to cut polyimide films.
PI film laser cutting machine, also known as picosecond laser cutting machine, is equipped with ultraviolet picosecond laser, with delicate light source and small heat affected area. It is outstanding in the processing of polymer materials such as polyimide, non-metallic materials such as ceramics, quartz and various metal and alloy materials such as tungsten copper. It can also be used for cutting and opening FPC / PCB plates, and is widely used in camera modules, fingerprint identification and other fields.
