Any electronic product is inseparable from the application of PCB circuit board, which is an important device in the electronics industry. Portable and multi-functional electronic products have high requirements on printed circuit boards (PCBs), and the application of laser processing can better meet the quality requirements. Let Leapion Laser share the laser processing technology in PCB circuit boards.

1. Laser cutting technology

With the continuous development of the manufacturing industry, the miniaturization and high speed of electronic products have put forward higher and higher requirements for circuit boards. The processing of PCB products has also derived a huge industry market, of which the application of PCB laser cutting processing technology is an important part.

The application of PCB laser cutting technology in the PCB industry started earlier. We have a special article before that introduced the application advantages of laser cutting machines in PCB circuit boards. You can learn about them.

2. Laser marking technology (PCB QR code marking)

1) In the application of PCB QR code laser laser engraving, UV ultraviolet laser marking machine, CO2 laser marking machine, fiber laser marking machine, green laser marking machine, etc. are selected according to different paint surfaces and materials.

2) With the development of thinning and miniaturization of electronic equipment, the size of the PCB board is very small. In order to save space utilization, usually, the QR code marked on the PCB board is very small, such as 2x2mm size 2. One-dimensional code, and contains more than 20 character information, the marking of this kind of high-density, small-format two-dimensional code can only be realized by PCB laser marking machine technology.

3) Compared with the inkjet method, the PCB laser marking technology is more environmentally friendly and economical, and the permanent mark will not be easily erased.

4) Non-contact non-destructive marking, will not damage the substrate, high processing accuracy, small format can achieve 0.12x0.12mm 31-digit two-dimensional code laser marking, making

5) The PCB laser marking machine has a long service life and can work continuously for more than hundreds of thousands of hours; and the processing efficiency is fast, a two-dimensional code can be completed within 1 second, the marking is exquisite, and there is no obvious tactile feeling when touched by hand, and manual operation is required. Simple, fool-proof processing.

6) The application of PCB QR code marking can enhance the brand effect on the one hand, and facilitate the traceability of product quality and market direction on the other hand. It is convenient for management and at the same time helps to improve the market competitiveness of products and effectively realize the control of automatic production of products.

Now, PCB laser marking has been fully rolled out in the market, and there will be a very broad market in the future.

3. Laser welding technology

Since the development of laser welding technology, it has continuously penetrated into every industry. With welding efficiency and quality, laser welding has high quality and long service life, and can realize automatic production. Many manufacturers are using it.

The application of laser technology in the PCB industry also includes laser drilling, line engraving, laser tin spraying and other technologies, which will be introduced later by Leapion laser.
