Vacuum pump in the vacuum coating equipment

Vacuum pump in the vacuum coating equipment

Vacuum pump in the vacuum coating equipment, equipment operation will generate heat, if increase the hot conditions, such as the temperature increases, so the load of equipment will also increase, under this situation, how to maintain?
First: to prevent the vacuum pump or avoid vacuum pump is placed in the sun! As far as possible let the vacuum pump in a cool place, vacuum pump should pay attention to in the outdoor place cannot let vacuum pump exposure in the sun. Itself high vacuum pump temperature during work time, if it is difficult to heat, temperature vacuum pump increases, once reach zero boundary temperature of the vacuum pump, mechanical failure will occur!
The second: the vacuum pump in ventilated place or interior is equipped with cooling device can also be! Willing to also is same, just to let the vacuum pump cooling performance is better, the lower the temperature in the vacuum pump work as much as possible.
Third: material timely replacement. One of the most important is: oil and oil mist separator (exhaust filter)! These two kinds of material must be timely replacement. Exhaust filters if scrap or other quality problems when replacing the first time! Oil a color change color, sediment increase, began to appear the phenomenon such as emulsifying can't just stay in the refueling and maintenance, all want to replace the vacuum pump oil.
Fourth: before the hot weather of vacuum pump for a thorough cleaning and maintenance.
Fifth: the remaining matters needing attention of basically the same as regular maintenance.

What to buy vacuum coating machine equipment should pay attention to?

What to buy vacuum coating machine equipment should pay attention to?

Large investment funds items, we will be very careful when buying, it would be ready before the purchase of the required detailed understanding of the work done, a vacuum coating machines are not cheap, with the fast development of vacuum coating industry, for the film to be coated product requirements are also gradually increase, for the use of materials is also gradually expand the scope, and that the vacuum coating machine to keep the product in terms of rhythm with a certain challenge. Now we have to introduce a few precautions to purchase vacuum coating machine.

First, the configuration of the vacuum system: quality and price will always be proportional, regardless of what kind of technology the purchase of machinery and equipment, evaporation or, ions or, magnetron sputtering, or, the same function of the machine, with different configuration, the price is definitely a difference. In general, the use of materials on behalf configured well, the natural life will be longer, the efficiency will be higher, film better.

Second, the vacuum coating machine housing: If the surface, basically difficult to see is good or bad, not only from the surface gives the visual effect to distinguish the case basically every vacuum equipment manufacturers can be processed out. For the case should focus on sealing, welding is very important, if you buy back the equipment found to have leakage problems that customers will be very headache, even indirectly, some inexplicable problems, causes leak occur often because processing not good. Therefore, customers choose to buy vacuum coating machine / coating equipment when we must focus on processing power.

Third, the core technology: the different processes used in the core is not the same, unified call evaporation source, but it is a target head or electronic guns. If you do not have good evaporation source, basically not try to complete the stable quality of the coating. Good evaporation source is needed after years of constantly improve and perfect coating of data and then come out, do not understand the process of evaporation source manufacturers difficult to do. If what manufacturers say that their equipment does not include the process, some do not buy it.

Fourth, field trips, samples proofing: Before you buy or coating equipment vacuum coating machine, take samples to coating, check the film coating system is not able to reach their own requirements, its technical service and after-sales service is not perfect, combined with the above mentioned consulting Consulting more points, the last shop around

Vacuum coating vendors would introduce coating control mode wavelength

Vacuum coating vendors would introduce coating control mode wavelength

Vacuum coating machine, vacuum coating vendors would introduce our materials for its membrane layer of materials, figure 1. The experimental results obtained for SiN film plating. Curve 1 is the reflection spectrum of epitaxial wafer before coating, curve 2 and 3, respectively corresponding to the film thickness of 95 nm and 135 nm, film thickness with elliptic partial instrument to measure. From the curve 1, film e - lh peak at 840 nm, e - hh peak at 848 nm, the location of the pattern wavelength at 832 nm. In type Chang Tong modulator, mode wavelength position should be in e ￣ hh peak of long wavelength direction; And often shut device, pattern wavelength location should be near the e - hh peak, and the top must be decreased membrane plating, otherwise the device will work in the saturated zone, reduce the modulation features of the device. Because the pattern wavelength position is not appropriate, to adopt the method of plating SiNO minus the membrane to move mode wavelength.
Vacuum coating machine, vacuum coating vendors would introduce 2 film thickness of 95 nm by curve of reflection spectrum, the wavelength shifted, but as a result of surface reflectivity, ASFP cavity resonance absorption and exciton absorption compared to compare weak, so can not see clearly on the curve mode wavelength position. Measured with elliptic partial instrument, the film refractive index of 1.8 or so, move about 10 nm wavelength by a theoretical calculation of the mode, at about 842 nm. After coating, e - hh peak of significantly lower reflectivity, although the model at this time Wavelength in e - hh peak position, but because the pattern wavelength from closer to make e - hh exciton peak near the reflectivity of reduce a lot.
Vacuum coating machine, vacuum coating vendors would introduce three film thickness of 135 nm by curve reflection spectrum shows that compared with the mode wavelength before coating, coating mode wavelength decreases after, from the original 832 nm to 832 nm. Film refractive index is 1.8, from the above theoretical analysis shows that when the refractive index of 1.8, film thickness increased to 135 nm, the model about 10 nm wavelength will drop, curve 3 belongs to this kind of situation.
