Flexible circuit board (FPC) has many advantages such as saving space, reducing weight and high flexibility. The demand for FPC at home and abroad is increasing year by year. The characteristics of flexible circuit board (FPC) make it an alternative to rigid circuit board and traditional wiring scheme in many occasions, and it also promotes the development of many new fields.
Application of laser marking machine in flexible circuit board industry
The current flexible circuit board is mainly made of printed circuit boards based on polyimide or polyester film. It has the characteristics of high assembly density, small size, light weight, etc., and is widely used in the connection parts of electronic products. At present, it is in the stage of small but rapid development of the industry. It has good electrical performance and can meet the needs of the installation design of micro and high precision. It is the material for the miniaturization and mobile design of electronic products. It is difficult to damage the wire by freely bending, winding, folding and multiple bending. It can be freely arranged according to the space layout requirements. The integration of components and wire connection can be achieved in different spaces, which greatly reduces the volume and weight of electronic products. It is a powerful guarantee for the high density, miniaturization and high reliability of electronic products.
With the development of flexible circuits now, smaller and more complex flexible circuit boards will become the future development direction in the future. The traditional processing methods are difficult to meet the processing needs due to their own conditions. In order to achieve more refined flexible circuit design, more refined processing solutions are needed.
Because the current UV laser marking machine has a high-energy laser beam, which can convert light energy into chemical energy when acting on polymer materials such as PI. Under the action of precision laser beam, some chemical bonds connecting the atoms and molecules of substances change, thus achieving the purpose of surface treatment.
In this processing process, due to the processing time and energy concentration, the surface of the processed items will hardly be damaged, which can be effectively guaranteed in terms of processing accuracy and quality. Although the price of the current UV laser marking machine is still higher than that of the traditional processing equipment, the marking process requirements are now difficult to reach by other processing methods. It is believed that in the future, laser technology will provide more sophisticated processing solutions for flexible processing, and provide a strong guarantee for the smaller and more complex flexible circuits in the future.
