High power UV laser for FPC cover film cutting

FPC cutting

I. Introduction


With the continuous development of science and technology, laser technology has been widely used in many fields. Among them, high-power ultraviolet lasers have significant advantages in FPC (flexible circuit board) cover film cutting. This article will focus on the application of high-power UV lasers in FPC cover film cutting.


2. Characteristics of high-power ultraviolet lasers


High-power UV lasers have high beam quality and energy density, which can quickly heat materials and achieve efficient cutting. Its wavelength is short and has high penetrating power. It can act on the surface of the material and heat it quickly, causing cracks inside the material to achieve cutting. In addition, high-power UV lasers also have high processing speed and good cutting accuracy, which can effectively improve production efficiency.


3. Application of high-power UV laser in FPC cover film cutting


FPC cover film is a film used to protect circuit boards and can improve the corrosion resistance and insulation of circuit boards. Traditional FPC cover film cutting methods mainly include mechanical cutting and chemical etching methods, but these methods have problems such as low cutting efficiency, poor precision, and environmental pollution. High-power UV lasers have obvious advantages in FPC cover film cutting.


First of all, high-power UV laser can achieve fast and precise cutting of FPC cover film. Through high-precision optical systems and advanced control algorithms, high-precision cutting can be achieved to ensure cutting quality and efficiency. Secondly, the heat generated during the cutting process of high-power UV laser has a small impact range, which can effectively reduce the heat-affected zone and reduce material damage and deformation. In addition, due to the extremely fast processing speed of ultraviolet lasers, the production cycle can be greatly shortened, production efficiency can be improved, and production costs can be reduced.


High-power UV lasers have significant advantages in FPC cover film cutting. Its high-precision cutting and high-speed processing speed can effectively improve production efficiency and product quality, while reducing production costs and environmental protection pressure. With the continuous development of science and technology, we have reason to believe that the application of high-power UV lasers in FPC cover film cutting will become more and more widespread and become an important development direction of the future manufacturing industry.
