UV laser used in PCB laser cutting machine
Beyond laser UV laser cutting machine cold light PCB processing, when choosing a PCB laser cutting machine, corporate manufacturers will ask what kind of laser cutting machine to use for PCB, what size can be processed, what is the processing effect, and how fast is the laser cutting PCB In the same way, the price and other issues, in fact, the application of the processing technology of the UV laser cutting machine has been mature, the following is a brief introduction to the PCB UV laser cutting machine.
The composition and principle of PCB UV laser cutting machine
PCB ultraviolet laser cutting machine refers to the use of 355nm ultraviolet laser, through the beam expander, galvanometer, focusing mirror and other optical devices to focus to form a small spot, through the software to control the deflection of the XY motor of the galvanometer, the spot moves within the scanning range of the focusing mirror, By controlling the movement of the light spot, scanning in a certain area over and over again, peeling off the material on the surface of the material layer by layer, so as to achieve the purpose of cutting the material. However, if the scanning range of the lens is exceeded, it is necessary to control the material placement platform XY linear motor to move the splicing method, and choose the gantry structure or the XY platform structure according to the size of the material. Under normal circumstances, the focal length of the Z-axis linear motor is adjusted according to the thickness of the material. The focal depth of the ultraviolet laser cutting machine is relatively short, and the focal length needs to be adjusted at any time according to the processing requirements.

Processing size of PCB UV laser cutting machine
The size of the stand-alone UV laser cutting machine is theoretically unlimited, and it can be customized according to the needs of major manufacturers.
The effect of PCB UV laser cutting machine
The effect of UV laser cutting PCB is closely related to the parameters of the laser, optical path components, processing speed and other conditions. Under normal circumstances, high frequency, narrow pulse width, and high single pulse energy of the ultraviolet laser cutting machine are required. The external optical path components should be used with high precision as much as possible. Device.

Speed of PCB UV Laser Cutting Machine
Ultraviolet laser cutting speed has a great relationship with power, material thickness, etc. At the same time, it is necessary to take into account the effect of cutting. Generally speaking, the higher the power of the UV laser, the faster the cutting speed, and the thinner the thickness, the faster the cutting speed.
The price of PCB UVlaser cutting machine
The right to decide the price is in the hands of the company, so each company needs to have a practical goal after the inspection, which is determined according to actual needs, while taking into account issues such as service life and maintenance costs.
In order to fully use the PCB UV laser cutting machine, it still needs the cooperation of major enterprise manufacturers and laser suppliers. As long as they understand each other and are familiar with each other, a win-win situation can be achieved.
