Let coating equipment maintenance has a higher value

Let coating equipment maintenance has a higher value

Each device has its own life, maintenance purpose is to maximize equipment performance and potential to improve the efficiency of the use of time and the value has risen considerably.
We often find that some coating plant equipment dirty, lots of grease, a lot of dust, many employers feel that as long as the equipment can do on the line, so clean out is no relationship between the external and internal, a complete waste of time is not necessary, did not realize the device from dust and grease will have an impact, it will reduce the life and performance of the equipment.
For maintenance coating equipment, maintenance and repair must have routine maintenance and periodic maintenance, equipment, the most important is attentive to the key analytical issues, well you can take a lot less detours, I believe that every teacher have deep get experience.
Routine maintenance coating equipment, for the conventional part of the day should be no time to check, for example, the oil will not be less, if the day was found in the production facilities have an adverse signs, even a little problem should be resolved immediately, less oil To add promptly, although oil is periodically replaced, parts can see a problem and do not work properly and so thoroughly broken in change, a problem may cause a chain reaction of problems arise more big losses, saying the remedy is better cooked rainy day.
Regular maintenance coating equipment, routine maintenance is not a substitute for regular maintenance, routine maintenance is shallow, regular maintenance should be deeper, who do not want to see is the machine problems in production led to production planning affected, coating operational status of the device directly affect product quality, production schedule, to ensure good operation of the equipment, establish and improve equipment maintenance and repair systems, standards are a must.
Many coating equipment pre-qualified, but often fails, coaters are not withstand even the best choice to use a lot of problems have appeared in the daily use, the machine does not allow the normal flow of work, there is no maintenance of equipment over . In good equipment is not withstand the toss, do not let the cold equipment at a critical moment, a little short of time to spend a day in maintenance equipment, perhaps unexpected potential value.

Why double door coater coating when two gate voltage difference is very big

Why double door coater coating when two gate voltage difference is very big

Should be a magnetron sputtering, but don't know whether I reaction sputtering, if is reactive sputtering, low voltage film slow is normal. Have not seen a similar coating machine, don't know whether two cavity is same? If not, there may be a flat place, but the speed is fast enough, show that the pressure is no problem. In addition, the stand or fall of magnet tests only target on the surface of the magnetic field strength is good, the higher the magnetic field intensity, the lower the voltage. Power supply is intermediate frequency or dc or rf, twin target, if not need to pay attention to whether the power cord connect anti? Made no mention of target's own reason, may be in the air oxidation, surface to sputter, with fine gauze after polishing time target practice.
In addition, the target water not too cold. When exposed to atmosphere are easy to be surrounded by water. Swap of vacuum coating machine equipment suggested that the two target location, so you can find out the cause of the target and magnet or coating chamber.

Vacuum coating machine coating principle is what?

Vacuum coating machine coating principle is what?

Vacuum coating machine coating principle is what? Vacuum coating machine is the product into during equipment widely used, with the rapid development of electronic industry, vacuum coating machine, coating quality gradually improve, so that we use in our everyday life come into contact with the plating products more and more.
In a sense, vacuum coating was also determined by the vacuum coating oil, in the vacuum coating, coating oil mentioned strong adhesive coating and the role of the metal film, it is in pieces at the bottom of the coating, plating and surface coating in the plating.
1. Vacuum environment

How to buy vacuum coating machine, it is necessary to pay attention to

How to buy vacuum coating machine, it is necessary to pay attention to

With the vigorous development of the vacuum coating industry, also more and more high to the requirement of vacuum coating machine, because the customer's products are constantly upgrading, all kinds of new product material appeared constantly, all kinds of coating requirements more and more complex, we now buy vacuum coating machine pay attention to the following three points:

First of all, the processing power of the vacuum coating machine shell Seemingly cases do not have what difficulty, every vacuum equipment factory can work, but a lot of knowledge, a device of light is not enough to have good vacuum system, vacuum chamber if processing is bad (such as welding), that this equipment to buy back to the customer will have a headache, processing of bad equipment often appear a few small leakage, pressure is not stable, and even some puzzling problems (such as stainless steel plating on titanium as long as more than 3 minutes in furnace into purple, no more than is normal, this is we meet client instance). So here we sincerely recommend our customers to buy the vacuum coating equipment as far as possible choose processing strength of the manufacturer (have) of machining center and other processing equipment.
Second vacuum system configuration as the saying goes, a penny a points goods, price and quality is actually a proportional to the relationship, even if is the same function of the equipment, different configuration, the price must be different, configured vacuum coating machine, long service life and easy to operate smoothly, but the low configuration equipment, problems, foibles, seriously affect the production schedule.
The last is not package process, don't buy equipment.
This is one of the most important among three o 'clock, because the core of the realization process is evaporating source (target) or electron gun, etc.), ready to evaporation source to develop the stability of the coating process, don't understand the process of manufacturer also do bad to evaporation source, good evaporation source is through continuously to improve to make all kinds of coating research, craft do bad evaporation source also do bad, so come to the conclusion that do bad evaporation source manufacturer all need not consider. Generally buy vacuum coating machine, therefore, must choose a proofing coating machine manufacturers, to take samples to plating, plating out samples can reach their testing requirements, in combination with the appeal two decision to buy or not. Equipment manufacturers must do a good job in the factory before the church your own equipment operators after the coating process and equipment factory warranty free coating process consultation and guidance.

The development of the vacuum magnetron sputtering deposition

The development of the vacuum magnetron sputtering deposition
So-called sputtering can be in the charge particles (usually with positive ions of inert gas) to bombard solid surface (hereinafter referred to as the "target"), so as to cause the target material on the surface of the atoms or molecules to escape from it a phenomenon. This phenomenon is glover (Grove) in experimental study in 1842, the cathode corrosion problems, cathode materials have been migrated to the vacuum tube wall. Vacuum coating machine to use this method of sputter deposition film on the substrate was introduced in 1877. Using this approach, however, exist in the early stages of the deposition film sputtering rate is low, film speed is slow, and must be set on high pressure and the device into the inert gas and so on a series of problems. As a result, the slow development of nearly eliminated. Only in the strong chemical activity of precious metals, little metal, get a small amount of medium and compound material application. Until the 1970 s, with the advent of magnetron sputtering in a timely manner, making sputtering deposition has been rapid development, started to go the way of revival.
This is because the magnetron sputtering method by orthogonal electromagnetic field on electronic constraints, increased the probability of electrons collide with gas molecules, such not only reduced on the cathode voltage, and improve the positive ions on target cathode sputtering rate, reduce the probability of the electron bombardment substrate, thus reducing its temperature, namely with the "high speed, low temperature" two big characteristics. In the 80 s, although he appeared just ten years, it will stand out from the lab, truly entered the field of industrial production. And, with the further development of the science and technology, in recent years in the field of sputtering coating introduced ion beam enhanced sputtering, ion source using broad beam intensity flow combined with magnetic field modulation, and combined with the conventional diode sputtering formed a new sputtering mode. And, again will be introduced to the intermediate frequency ac power magnetron sputtering target source. This is called the twin sputtering targets intermediate frequency ac magnetron sputtering technology, not only eliminates the anode effect "disappear". And also solve the problem of cathode "poisoning", which greatly improved the stability of the magnetron sputtering. For large-scale industrialized production of the preparation of compound film provides a solid foundation. Revival and development of coating has rapidly in recent years as people quite a new preparation technology of thin film and active in the field of vacuum coating technology.
