Second, the right side of the composite unit adjustment method:

1: When the ionization meter determines the pumping to show the above vacuum.

, turn off the auto first, then turn the resistor 2 on, and then slowly adjust the zero small hole potentiometer with a lot.

bring it to display -1).

2: Will open automatically.

3: After work, open the door.

4: Slowly adjust the es with a word batch so that it is adjusted to display 5), so that the composite meter is adjusted.

5: Generally speaking, the composite vacuum gauge should be adjusted and calibrated for a period of time (about 10 days), otherwise there will be measurement errors and affect the pumping time. (The description of the composite meter is clearly written, please read it carefully).

6: After the resistance tube has been used for a period of time (about a month), anhydrous alcohol can be used.

The first grade Hefei industrial grade can also be left on the page.

Hello, our company Zhaoqing Zhenhua Vacuum Machinery specializes in R&D and production of various types of vacuum coating equipment!

For details, please call 0755-26500053. When purchasing Zhenhua vacuum coating machine, our company will train operation and maintenance staff.

What products do you plate? You can be specific. Our coating process is slowly invading.

There is a short period of time when the vacuum level becomes low, but it will rise back quickly and steadily.

And what kind of coating are you? Heating or current? If it is a heating coating, the kind of tube furnace is to ventilate the airflow, the vacuum degree will be a little unstable, so before starting the evaporation film should be vacuumed for a period of time, and to stabilize for a period of time after ventilation, generally we have to pump for more than half an hour, the other is the vacuum coating instrument, which is heated by adjusting the current, for this, because you heat up faster, the impact on your vacuum environment is still relatively large, generally you will make the vacuum degree change more when you start to energize, At this time, you should reduce the current again, stabilize it, repeat it a few more times, you should always pay attention to the vacuum degree when turning on the current, and turn off the current as soon as possible once it goes down, otherwise it will affect the quality of the membrane.

Or the film material evaporates into gas, which will decrease a little.

or ion plating, lower some normal. It's normal.

Or leak detection. In the state of air pumping, whether there are bubbles seeping, but if it is really bubble infiltration, it will be difficult to detect the specific place of leak detection, and it will be difficult to troubleshoot.

There are several possibilities that can be summarized in detail:

1。There is a slight air leak in the vacuum furnace.

2。Mechanical pump oil change.

3。The inner film layer of the furnace is too thick, and the furnace should be cleared.

4。The diffusion pump is oiled and cleaned and it will be fine.

Hope it helps

You are 1: Open the fine suction valve [main valve] The vacuum level of the coater drops suddenly, and then recovers immediately. 2: The vacuum level suddenly drops when the coating is just started. Or something else!

Hello! I think when pumping a high vacuum, it is a large deflation in the furnace, you have to check: 1

The product is oven baked and dried. 2.Furnace deplating cleaning.

3.Mechanical pumps, roots pumps, oil change cleaning. 4.

Diffusion cleaning and oil change. 5.Whether there is a sand hole leaking in the vacuum furnace.

You check, and contact me if you still have questions.

If you turn off the machine, you still don't want to operate it, and it is easy to have problems if the valve is wrong.

Maintain the pump alone, maintain it here can be used, you can open the roots pump, under the valve, in the look, there is no to minus one, there may be a leak.

Vacuum coating machine mainly refers to a type of coating that needs to be carried out under a high vacuum degree, including many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition and many other kinds. The main idea is to divide into evaporation and sputtering two kinds of scope of application: 1 Building hardware:

Bathroom hardware (such as faucets) door locks, door handles...

Pull it out slightly, and push it back immediately (maybe there is a gap between the door and the closure).

I would also like to know the specific information.

The whole machine is cleaned again, the door is closed and the air is pumped, and it is heated to 400 degrees for 3 hours. During the heating process, see if the vacuum is good, if the vacuum is off, then the equipment is leaking, you have to check the leak first. If there is no air leakage, the preheating process just now is considered complete, plating it and seeing.

Pita-force gauge.

It is measured by the principle that the resistance of the resistance wire changes with the change of temperature, and the change of the temperature of the resistance wire is related to the thermal conductivity of the surrounding gas.
