Cutting machine manufacturer explains in detail the working principle of FPC laser cutting

Laser cutting machines have been widely used in various industries, but some friends may not know too much about the principle of cutting FPC. The following laser cutting machine manufacturer introduces the laser cutting principle of FPC in detail. FPC is a printed circuit board with graphics made of flexible substrate. It is mainly used in mobile phones, laptops, PDAs, digital cameras, LCM and other products. It has the characteristics of high wiring density, light weight and thin thickness.. It is suitable for applications with complex circuits, high signal processing requirements, or special electrical or mechanical performance requirements.

The principle of all laser cutting is the same, only the laser configuration is different. The basic principle of the laser cutting machine is to focus the high-energy laser beam into a very small spot, forming a very high power density at the focus, causing the material to be cut to vaporize or melt in an instant, and then blow the molten material with the gas to form The process of cutting seams. Different lasers will affect the quality and efficiency of processing. The laser can be selected according to the customer’s actual application cutting needs. Laser cutting has the characteristics of non-contact processing, high degree of flexibility, fast processing speed, narrow slit, small deformation, wide adaptability and flexibility, and a wide range of cutting materials.

The working principle of the FPC laser cutting machine is to use a 355nm ultraviolet short-wavelength laser beam to scan the FPC surface, so that high-energy ultraviolet photons directly destroy the molecular bonds on the surface of the flexible material to achieve the purpose of removing the material. UV laser processing is a “cold processing”. The parts etched by this “cold” photolithography have a small heat-affected zone, smooth edges and minimal carbonization, which can ensure the best quality of the processed FPC products.

What are the processing advantages of men-luck FPC laser cutting machine? The laser processing method is non-contact processing, and the heat affected zone of the components during the processing is small; the high-performance ultraviolet laser has a small focused spot, uniform power distribution, small thermal effect, small slit width, and high cutting quality during operation; it adopts precision two-dimensional work Taihe fully closed-loop CNC system ensures rapid cutting while maintaining micron-level high precision; position sensor and CCD image positioning technology automatically position and focus, making positioning fast and accurate, saving time and worry, and high efficiency; with “cold processing” The effect is that it can cut different materials of different thicknesses. The edges of the cut contour are smooth without burrs and cracks. The heat-affected zone is small and there is no delamination and deformation caused by heat. No post-processing is required. The quality is stable, repeatable and precise. and high efficiency.

To sum up, FPC laser cutting machine, as an advanced non-contact processing method, has many advantages, can meet the increasingly complex FPC processing needs, and can ensure product quality and processing accuracy. With the continuous advancement of science and technology, I believe that FPC laser cutting technology will be more widely used and developed. Our company has a lot of experience in cutting processes for copper substrates, aluminum substrates, ceramic substrates, and stainless steel substrates such as FPC and PCB. We welcome new and old customers to make an appointment for substrate sample cutting services.
