Advantages of Laser Cutting in FCB and PCB Manufacturing

PCB is one of the important electronic components in the electronic industry. Almost every electronic device, such as electronic watches, calculators, computers, communication electronic devices, military weapon systems, etc., requires the use of printed circuit boards for electrical interconnection as long as there are electronic components such as integrated circuits. PCB has evolved from single sided to double-sided, multi-layer, and flexible, continuously moving towards high-precision, high-density, and high reliability, and continuously reducing volume, reducing costs, and improving performance, making PCB always maintain strong vitality in the development process of electronic devices.

Compared to hard circuit boards, flexible circuit boards have flexible material characteristics and have advantages such as easy turning, light weight, and thin thickness. The structure of soft board products is made of soft copper foil substrate and soft insulation layer adhered and pressed with adhesive (adhesive), which has many advantages that hard printed circuit boards do not have. For example, free bending, winding, and folding can be arranged according to spatial layout requirements, and can be moved and expanded freely in three-dimensional space, achieving the integration of component assembly and wire connection. The use of flexible circuit boards can greatly reduce the volume of electronic products, which is suitable for the development of electronic products towards high-density, miniaturization, and high reliability. Therefore, FPCB has been widely used in fields or products such as aerospace, military, mobile communication, laptops, computer peripherals, PDAs, and digital cameras.

1) High precision

Compared to traditional cutting techniques, the high accuracy of laser cutting is self-evident. Usually, taking the Daizu Superenergy MPS-0606LP model as an example, the positioning accuracy of laser cutting is ± 0.01mm, and the repeated positioning accuracy is 0.005mm. Suitable for cutting precision accessories and fine cutting of various craft characters and paintings.

2) Narrow slit

The laser beam is focused into very small light points, achieving a high power density at the focal point. The material is quickly heated to the point of vaporization and evaporates to form holes. As the beam of light moves linearly with the material, the holes continuously form narrow slits. The width of the incision is generally 0.10-0.20mm, and compared to traditional cutting techniques, the slit formed by laser cutting is very narrow.

3) Smooth cutting surface

Generally speaking, for industries or products with very high cutting requirements, it is not allowed to have any burrs. Traditional cutting techniques cannot meet such requirements, while laser cutting technology can achieve a burr free cutting surface.

4) Fast speed

Another significant advantage of the new laser cutting technology is its very fast cutting speed. Under normal circumstances, taking the Daizu Superenergy MPS-0606LP model as an example, the maximum acceleration can reach 1.5G and the maximum positioning speed can reach 60m/min, which is much faster than the speed of gongs and punches. For some demanding fields, laser cutting applications are also very frequent.

5) Good quality, no damage

Laser cutting belongs to non-contact cutting, and the cutting edge is minimally affected by heat. There is basically no thermal deformation of the workpiece, completely avoiding the collapse of edges formed during material punching and shearing. The cutting seam generally does not require secondary processing. The laser cutting head will not come into contact with the material surface, ensuring that the workpiece is not scratched.

6) Not affected by material properties

Laser can process steel plates, stainless steel, aluminum alloy plates, hard alloys, and substrates of various materials in the PCB industry. Regardless of their hardness, they can be cut without deformation. Laser processing has good flexibility and can process any shape, as well as cut pipes and other irregular materials.

7) Compared to punching machine processing, laser processing does not require molds, does not consume molds, does not require mold repairs, saves time on mold replacement, thus saving processing costs and reducing production costs, especially suitable for processing large products.

8) Material saving

By using computer programming, products of different shapes can be cut to maximize material utilization.

9) Increase the speed of sample delivery.

After the product drawing is formed, laser processing can be carried out immediately to obtain the physical product of the new product in the shortest possible time.

10) Safety and environmental protection

High equipment integration, small footprint, low processing waste, low noise, cleanliness, safety, and pollution-free, greatly improving the working environment.
