Ultraviolet laser cutting FPC flexible circuit board without carbonization

FPC flexible circuit boards, light, thin, soft, and flexible, are very suitable for the needs of portable medical equipment, and are widely used in medical equipment, such as ultrasonic equipment, probe equipment of various instruments, medical equipment buttons and so on. In order to meet the application needs of different customers, during the production and production process, it is necessary to perform processes such as plate cutting and two-dimensional code etching. Therefore, RFH355nm ultraviolet laser cutting, marking, and drilling technologies are required.

The S9 series of pulsed ultraviolet solid-state lasers developed and produced by RFH specifically for the 3C electronics industry have won the favor of FPC flexible circuit board manufacturers since they were put on the market. The following editor will explain the characteristics of S9 UV laser in detail:

Compared with products of the same type, S9 UV laser is smaller in size, more exquisite in design, and more stable in light output. The small and exquisite design means that users do not need to make a large optical path, which can greatly reduce costs, save space, and have good mobility. It is easy to install in the field of equipment such as flying marking. The S9 ultraviolet laser is not only compact, but also has a more stable cavity structure and stronger scalability than similar products. The same cavity can produce lasers of different powers, and the stability of different power ranges is greatly improved

At the same time, superior product quality is more competitive.

Ultraviolet lasers usually output wavelengths below 0.4μm, which is the main advantage of processing polymer materials. Unlike infrared processing, ultraviolet micro-processing is not essentially a heat treatment, and most materials absorb ultraviolet light more easily than infrared light. The short wavelength of ultraviolet itself has advantages for the mechanical micro-processing of metals and polymers. It can be focused to a point on the order of sub-micrometers, so it is widely used in the processing of fine parts.

For machine manufacturers, a good solid-state laser can effectively improve production efficiency and provide terminal equipment with stronger market competitiveness. The new product series of RFH pulsed ultraviolet solid-state laser S9 has a laser wavelength of 354.7nm and a wide range of repetition frequency (single pulse to 200kHz), which can be better absorbed by the material and is less destructive to the material. And it has superior beam quality (M2<1.2), which is strictly guaranteed in all frequency ranges; pulse width is <20ns@30k, and the heat-affected area is small during processing.

S9 series UV lasers also have unique Q-switching control technology, full digital intelligent power control, simple operation, low cost of hands-on, and suitable for various laser application control needs; the internal cavity self-purification system makes the laser long life, stable operation, and low Maintenance costs. We fully consider the convenience of machine control in the workshop, so the laser also supports communication with the computer, and the laser can be controlled externally through RS232.

After 13 years of development and precipitation, RFH laser currently has a senior laser research and development team composed of domestic and foreign professors, experts, and doctors. It has established an application process research and development department, a laser research and development department, and an electrical research and development department. It has obtained dozens of national patents and software. It is a "high-tech enterprise" and "Shenzhen high-tech enterprise". The rich technical reserve is the core competitiveness of RFH laser.

In terms of product guarantee, we will provide customers with a full set of services including procurement-quality inspection control before production-rigorous assembly process-finished product testing-warehousing quality inspection-pre-delivery inspection-after-sales service to overcome your purchase, installation, commissioning, and use Technical problems in all links, and provide high-quality after-sales service, check at every level, to ensure stable quality and consistency of equipment parameters with actual operating parameters.

At present, RFH Laser has launched the 3W-5W S9 series of ultraviolet lasers, which will increase to 8W, 10W, 12W, 15W in the future. This series can be widely used in electronic product marking, electrical appliance shell marking, food and drug production date Marking, consumer electronics micromachining, etc.
