How to measure the thickness of vacuum coating film?

How to measure the thickness of vacuum coating film?

In the use of vacuum coating machine after coating, in order to measure the thickness of the film, may be measuring the thickness of the film with what method?
Quartz crystal is the most direct coating method trace balance method (QCM design), the instrument evaporation source, can be directly driven by the PID control loop drive panel, keep the evaporation rate.
As long as the instrument connected with the system control software, it can control the entire coating process. But the accuracy of the (QCM design) is limited, in part because of its monitoring is the quality of the coating instead of the optical thickness.
And although the QCM design is very stable at low temperatures, but at high temperature, it becomes very sensitive to temperature. After a long period of heating process, it is hard to stop sensor is sensitive to fall into this area, which cause significant error on membrane layer.
Optical monitoring is the first choice for high precision coating monitoring way, this is because it can be more precise control of film thickness (if used properly).
Accuracy improvement comes from many factors, but the most fundamental reason is the optical thickness monitoring.

Works multi-arc ion plating machine and application description

Works multi-arc ion plating machine and application description

Multi-arc ion vacuum coating machine is an efficient, safe, pollution-free ion plating equipment, with deposition speed, ionization rate, ion energy, the equipment is simple, low cost, the advantages of producing a large quantity.
Ion plating fact ion sputtering, the conductive target, DC bias power supply; non-conductive targets, using pulsed bias supply. Some multi-arc ion coating machines, you may also need a DC arc or pulsed arc power supply. Bias power supply is in fact between the cathode and the anode position sample bias electric field where the formation is generally negative high voltage cathodes. Free electron emission cathode surface directional acceleration in the electric field emission electron impact gas molecules, so that the ionization, and the gas is expelled electrons are accelerated by the electric field of continuing ionized molecules of other gases, continuous form avalanche effect, hit the gas wear, the formation constant of ionization current. In this case ions are accelerated to bombard the target, the target material atoms expelled surface, and deposited on the sample surface.
Application of multi-arc ion coating machine, multi-arc ion coating machine for different grades of hardware products, general construction hardware, locks, multi-arc ion plating equipment capable, high-grade products such as strap, case, glasses , mobile phone shell, golf equipment, sanitary ware, jewelry, and other commonly used arc / IF (+ DC) magnetron sputtering composite coating equipment, the choice of the size of the models based on loading. The device can be plated gold color, rose gold, brown, brown, tan, blue and other decorative film.

Vacuum coating machine system characteristics

Vacuum coating machine system characteristics

Vacuum coating machine in plasma beam sputtering, uniform sputtering ion etch target surface, and will not make the target surface oxidation. Compared with magnetron sputtering, the plasma beam is generated by the rf plasma source and the role of the magnetic field is the plasma beam convergence and deflection to the target surface, therefore, although plasma beam sputtering coating system also has a magnetic field, but its effect to the magnetic field does not control sputtering, which abandoned the magnetron sputtering caused by uneven magnetic field in the "magnetic control" shortcomings. In sputtering, after the completion of the target material utilization rate can be as high as above 90%.
  Vacuum coating machine, magnetron sputtering and plasma beam sputtering target surface etching after contrast figure. Due to greatly improve the utilization rate of target material, has solved the difficult to overcome shortcomings of magnetron sputtering, which results in uneven etching of the target poisoning
Vacuum coating machine in addition, magnetron sputtering produce sputtering runway due to uneven magnetic field on the back of the magnet, the magnetic field is prone to oxidation zone, so it is difficult to deposit of ferromagnetic materials, and in the plasma beam sputtering with no magnet as plasma constraint, ability of ferromagnetic material coating, and can use the thick target material, in figure 3 experimental cobalt metal thickness is 6 mm. For iron, nickel, chromium and ferromagnetic compounds, plasma beam sputtering are also has a high sputtering rate.
  A further advantage of application of the coating technology system, when the electromagnetic coil polarity reverse connection, due to the direction of the magnetic field produced change, plasma beam bombardment under the action of a magnetic field of the substrate, thus substrate cleaning action, as shown in figure 4. This can actually make the application of the technology of coating machine to omit conventional coating machine cleaning with ion source.

Vacuum coating vendors would coating technology application profile

Vacuum coating vendors would coating technology application profile
Is the most common wet coating deposition process we see glass coated with silver mirror, in some places is still in use today. Common wet French pattern on the plating items is to use chemicals to produce chemical reaction, reaction of adhesive on the surface of plated items, and combine together to form a layer of coating.
Wet coating work elements are:
1. Chemical agents to participate in chemical reactions
2. The chemical reaction pool
3. The auxiliary additives
4. The catalyst
5. Reaction electrode
We can see that due to the preparation of coating chemical reaction method, people can't accurate control of chemical reaction in the pool every small areas of the situation, to a great extent, people couldn't sophisticated control layer in the process of production of uniform thickness. In quite a number of cases is plated items do not allow to have a chemical reaction. For example, in the single pervious to light glass coating production such as glass and chemical reaction is likely to damage of the glass surface, pervious to light fall, it would be lost to the coating. Were the most serious questions, most used chemicals, auxiliaries, strong catalyst are polluting, some are highly toxic, he brings to the human and the nature, even catastrophic damage is huge. Some film system cannot be prepared with chemical method.
