RFH UV laser cutting earphone film does not turn black or yellow

The 3W5W ultraviolet laser has little thermal effect, and the earphone film will not be burnt.

355nm UV laser cold processing earphone film does not turn black, yellow and deform

The world needs music, and the careful taste of music requires the help of headphones. The invention, design and production of earphone membranes are particularly important for the performance of earphones. Through the small and thin earphone membrane, sound enters the ear canal, making the world more abundant. In the production process of the earphone film, the most easily encountered problem is how to ensure the accuracy of its cutting and the problem of black and yellow after the earphone film is cut.

In order to cut more accurate earphone film, the headset manufacturer from Dongguan ordered two RFH UV lasers to participate in the cutting of the earphone film. In the past, the earphone film cutting used the traditional cutting mode, and the traditional mode is no longer used in the current production in terms of speed, quality and cost. On the other hand, RFH ultraviolet laser, 335nm wavelength, small spot and frequent speed of light, make this non-contact processing method of laser more suitable for the production of earphone film.

In order to solve the problem of cutting accuracy, RFH chose a cold light source with narrow pulse width and high peak power to make its cutting accuracy up to 0.2mm, which fully meets the installation requirements of the earphone film. In addition, the output energy of cold-worked violet light can stimulate the photochemical reaction of the material, and at the same time avoid the blackening, yellowing and deformation of the material caused by excessive heat output.

As far as the current laser market is concerned, RFH’s major breakthroughs are not only for earphone membranes, but also have different degrees of improvement in many fields. With RFH that changes the goal of China’s laser technology industry, we will impress customers with sincerity, change the industry with innovation, and use Belief keeps going.
