What are the working principles and characteristics of UV-LED exposure machine? Next, Xiaozhao will explain to you!

1. Power saving, energy saving and cost reduction - When the LED reaches a certain brightness, only about 15 watts of energy will be consumed, while the traditional lamp will consume 1500 watts of energy to achieve the same brightness. Even compared with the UV halogen lamp, 80% of energy can be saved, so the LED lamp is very energy-saving and environmentally friendly.

2. The lamp source system is guaranteed for 3 years and has a long service life - LED lamp has a service life of more than 20000 hours.

3. Wider application range - LED light emission is not infrared heating, and its heat release is low, so it will not affect the transmission of media (such as foam plastic plate, foil film, PVC, etc.) that are easy to be heated and deformed in the printing process. In this way, the application scope of media is more extensive.

4. Fast reaction (switching) time - LED light does not need to be preheated, and can be printed immediately after startup, thus improving productivity.

5. High safety - LED lamp has no UVC rays, no ozone release and is not easy to be damaged.

6. High stability - The printing quality of the UV ink-jet printer is closely related to the UV drying and curing process. The stability of the LED light makes the output energy predictable and stable, so the printing effect is also predictable and stable.

7. LED allows ink to be deeply solidified - LED light emits light with a wavelength of 395nm, which allows ink to be deeply solidified, so it will not occur when the surface of the printed matter is dry but the bottom layer is not. Printing on various media has strong adhesion and scratch resistance.

8. The products have applied for national patents and obtained four seven national patent certificates. Now the high-power UV-LED exposure machine with independent intellectual property rights is mass produced and listed, which will save more than 85% of the energy compared with the traditional metal halide lamp exposure machine.

9. In the face of high labor costs, the manual model will be upgraded to automatic equipment. The CCD automatic alignment LED light source exposure machine currently produced by SUN-FUBAO is widely used in mass production.

Exposure machine is an indispensable equipment for modern manufacturing of printed circuit board (PCB). In the manufacturing process of PCB, one of the most critical processes is to transfer the negative image to the copper foil substrate. First, a layer of photosensitive material (such as liquid photosensitive adhesive, photosensitive dry anti-corrosive film, etc.) is coated on the substrate, and then the photosensitive material coated on the substrate is subjected to light radiation to change its solubility. The resin in the non photosensitive part does not polymerize, but dissolves under the action of developer, and the resin in the photosensitive part remains on the substrate to form an image. This process is exposure, which is the process completed by the exposure machine in the production of printed circuit boards.
