Shanghai futanxi Electronic Technology Co., Ltd. mainly produces: UV LED point light source, UV LED surface light source, UV LED line light source, UV LED oven and other product equipment. It is a semiconductor UVLED exposure method, suitable for using UVLED exposure machine to expose wafer. The semiconductor UVLED exposure machine consists of at least one exposure lens carrying a wafer and a liquid circulating device supplying liquid between the wafer and the exposure lens during exposure.

 

 

 

 

The utility model is characterized in that before the semiconductor UVLED is exposed, the alignment phase is subject to an alignment operation by using at least one alignment light source, wherein the alignment light source has a specific wavelength, and the influence source of the liquid volatilization alignment light source is minimized to prevent the liquid from flowing from the liquid. Affects the above alignment operations.

 

 

 

 

Principle and characteristics of semiconductor UVLED exposure machine:

 

 

 

 

1. It can save energy and reduce cost. When the UVLED of semiconductor UVLED exposure machine reaches a certain brightness, it only consumes 15 watts of energy. However, even if the traditional lamp uses UV halogen lamp, it also needs 1500 watts of energy to achieve the same brightness. It can also save 80% of energy.

 

 

 

 

 

2. The illumination of LED light is not infrared heating, and the heat released is very low. Therefore, UVLED ink will not affect the medium (such as foam board, foil, PVC, etc.) in the printing process easy to be hot deformation. In this way, the application of media is more extensive.

 

 

 

 

 

3. The reaction time is fast, the LED light does not need to be preheated, it can be printed immediately after startup, and the production efficiency can be improved.

 

 

 

 

 

4. High safety and stability. The printing quality of UV ink jet printing machine is closely related to the UV drying and curing process. The stability of LED lamp makes the output energy predictable and stable, and the printing effect is the same. Predictable and stable.
