uvled exposure machine What is it, what is its development process, and why more and more companies are now willing to choose UVLED exposure machines instead of traditional ones. Yongcheng Optoelectronics exist uv I have ten years of experience in the industry and have been working hard in this industry for so many years. Next, I will answer these questions one by one for everyone.
first What is a UV-LED exposure machine? UV-LED exposure machine At once It refers to a device that transfers image information on film or other transparent objects to a surface coated with photosensitive material by turning on a light. Among them, the UV-LED exposure machine uses UV-LED ultraviolet light source with LED chip as the luminous body. The traditional light source is a mercury lamp, which is currently being slowly eliminated. In addition, UV-LED exposure machine equipment is widely used in my country's optoelectronic industry at this stage and plays a decisive role.
At present, the new exposure machine is equipped with the application of UV-LED cold light source curing machine. It also has precision double aspherical quartz lenses that can make the parallel half-angle of light less than 2° and the line resolution can reach 50um/um (ordinary machine is 100um/um). Moreover, the absence of infrared thermal radiation avoids the film expansion and contraction effect, ensuring high-fidelity image transfer quality and almost no light attenuation, which fully reflects the higher stability of UV-LED light sources in the manufacturing process. It not only improves the qualification rate of the product, but also does not produce polluting ozone and is environmentally friendly. It is an ideal substitute for the ordinary mercury lamp exposure machine currently used in PCB circuit board production.
The development history of uvled exposure machines in China
1. Based on the current market development trends and the analysis of the broad market demand, it is concluded that it has become an inevitable trend for UV-LED exposure machines to replace UV mercury lamp exposure machines. UV-LED exposure machines are mainly used in PCB circuit board manufacturing, semiconductor production and high-precision thin circuit exposure. It is very energy-saving and environmentally friendly, but the cost is relatively high and needs to be imported. Although the application market of foreign UV-LED exposure machines is wider than that in mainland China, importing foreign equipment is quite expensive, and the later use and maintenance costs must also be considered.
For ordinary enterprises, this will be a big problem. From the perspective of enterprise development, it will also become a bottleneck for enterprise development. Because the cost is too high and there is no advanced equipment, high-profit projects cannot afford to operate. If there is no high profit, there will be no funds to purchase new equipment, and the company will fall into an infinite loop, resulting in declining performance or being unable to make ends meet.
2. From this point of view, domestic UV-LED exposure machines are the best choice for small and medium-sized enterprises to get rid of the current situation. UV-LED exposure machines can not only enable small and medium-sized enterprises to turn around, but also promote the strategic development of large enterprises. In terms of performance, the LED parallel light exposure machine is precisely configured and has good functionality. UV-LED has the advantages of long service life and small energy attenuation. It can also improve production efficiency and product quality stability. It does not produce any pollutants, is green and environmentally friendly, and purifies the production environment. It is the best choice for exposure machine manufacturers.
Advantages of UV-LED exposure machine
1）Easy to use
2) Parallel light, precise optical combination
3）Cold light source, no film expansion and contraction
4）Scan back and forth, high uniformity
5) Deep solidification, high stability
6）Energy saving, emission reduction, consumption reduction, long service life
At present, the technical level of domestic UV-LED curing is gradually maturing, and UV-LED exposure machines are increasingly valued and accepted by more manufacturers. Faced with the current situation of rising production costs, choosing UV-LED curing/exposure equipment to replace traditional light sources can not only reduce production costs and improve production efficiency, but also reduce ozone production and reduce environmental pollution. It is simply killing two birds with one stone.
