Tao conductive ceramic evaporation boat operation suggestion

In recent years, the domestic market has continued to be popular, and the conductive ceramic evaporation boat is our company's flagship product. It is also firmly at the peak of the evaporation boat industry with its competitive technology and product quality advantages, but it is worth noting that Many users have many problems in operation, which also reduces the longest service life of the evaporation boat to a certain extent, which is not conducive to the best performance of the evaporation boat. For this problem, I will give you a detailed introduction to this topic. The operation points of the conductive ceramic evaporation boat produced by the company are to help the users to better exert the performance of the conductive ceramic evaporation boat.

1. The two rows of fixtures should be kept in alignment and the surface should be kept clean.

2. Use graphite paper on the end or side to ensure good electrical contact and heat transfer.

3. When the new boat is heated for the first time, put a piece of aluminum wire in the center of the groove to facilitate accurate determination of the temperature of the evaporation boat.

4. The contact point of the aluminum wire should be located between one-third and two-fifths of the length of the boat.

5. The first heating of the new boat should not be too fast, so as not to affect the deflation.

6. For the first time, the speed of the aluminum feeding should be gradually increased from the normal 75 percent, and the power should be gradually reduced to reach the maximum liquid aluminum spreading area.

7. The new boat is heated for the first time for 15 minutes, and the aluminum is sent to the vapor deposition in the above manner.

8. When each roll is finished, stop sending aluminum first, and then turn off the power after 30-60 seconds.

9. After turning off the power for about two minutes, until the evaporation boat cools to dark red, the vacuum is turned off.
