Quartz boat is fragile goods, the operation must be handled with care;
1.Two persons must cooperate with each other in the quartz boat boarding and disembarking, and they must move horizontally face to face in the process of moving;6. 3 Do not knock quartz boat with hands or other objects and tools in normal operation;
2. If quartz boat is used to need cleaning;By two cleaning personnel gently lifted on the special cart;One person pushes the car;Another person is holding the quartz boat by the side to prevent the cart from being hit and damaging the boat;
3. Before putting the quartz boat on the paddle and preparing to enter the furnace, it is necessary to confirm whether the quartz boat is placed smoothly and just to a fixed position;At the same time, attention should be paid to avoid the phenomenon of collision with equipment and other positions;
4. One person opens the door when the quartz boat needs to be cleaned and the door is fixed so that it does not swing and collide with the quartz boat;And determine that there is no contact with both sides of the door frame after gently pushed past;
5.During the cleaning process, please follow the process instructions and SOP regulations, and pay special attention to the cleaning machine to clean or clean 0K out of the boat before moving to the designated placement table, and the placement table must be kept clean and free of water stains;
6.after the wafer diffusion is completed, the quartz boat is in a high temperature state, and the quartz boat must be moved to wear high-temperature gloves;
7.in the quartz boat into the clean cabinet is to first open the door of the clean cabinet;Gently put into the layer to be placed, and gently on both sides of the cabinet at the same time force into the innmost;
8. In order to ensure the quality of diffusion, the quartz boat must be cleaned every 15 days;After cleaning, do saturation work according to the process instructions;
9. Staff who do not carry out quartz boat operation in accordance with the regulations will be seriously dealt with once discovered;
10.The quartz boat shall be handed over by each shift. If there is any abnormality, it must be reported to the manufacturing manager within 12 hours.
11. Those who fail to operate in accordance with the above provisions and damage the quartz boat will be given a heavy penalty: specific reference will be made to the company's economic loss and relevant internal regulations of manufacturing;
The Main Properties of Quartz Glass:
* Mechanical properties
Quartz glass is a brittle material with low tensile strength and high compressive strength. The latter is 20 times that of the former.
* Thermal performance
Quartz glass has a very low coefficient of linear expansion, very good resistance to thermal vibration, and is a poor conductor of heat.
* Optical performance
An important difference between quartz glass and ordinary glass is its good transmittance in the entire spectrum, especially in the ultraviolet and deep ultraviolet spectrum, which is not available in ordinary optical glass.
* Electrical performance
The main electrical properties of quartz glass are high dielectric electric field strength, low dielectric loss and low conductivity.
* Chemical properties
Quartz glass is a material with very good chemical stability and does not react with water, salt solutions and most acids.
* Radiation resistance
Compared with ordinary glass, quartz glass has excellent radiation resistance. Among them, synthetic quartz glass has the best radiation resistance and hardly produces color centers.
