ITO film winding vacuum magnetron coating machine

Roll-to-roll coating equipment - ITO film roll-to-roll vacuum magnetron coating machine

The winding vacuum coating equipment produced by Zhicheng Technology has the ability to obtain high vacuum, and can carry out high-precision reciprocating winding transmission of flexible film materials such as PET and PI. Control to realize fully automatic preheating operation of the vacuum system, air extraction and cold pump operation, infrared heating, etc.

Features:

This equipment adopts the servo motor to adjust the speed of the driving device of the flexible base material to drive the main roller, winding roller and unwinding roller, and cooperate with its tension sensor to realize the automatic control of the constant tension of the winding and unwinding during the film transmission process.

The coating main roll of this equipment is equipped with a set of fast and efficient vacuum coating special heating device, which is used to heat the surface of the coating main roll to the temperature required by the coating process during the vacuum coating operation to heat the substrate material to be plated .

The equipment is equipped with a set of large-area low-temperature refrigeration coils in the vacuum working chamber, and uses imported low-temperature cryogenic system to remove water vapor in the vacuum chamber.

The main engine includes a set of ion source system, which can modify the film layer, and includes water cooling and gas charging system, which has high uniformity.

MF twin and DC cathode systems can be configured according to process requirements.

The structure of the vacuum chamber is a horizontal semi-cylindrical body, and the whole vacuum chamber is made of 304 stainless steel.

The front and back of the vacuum chamber are each equipped with a rectangular observation window to observe the winding of the base material and the coating effect; the side is equipped with a circular observation window to assist in observing the uncoiling and coating of the base material.

The winding system consists of a base material winding device and a mobile power trolley. The base material winding device is composed of an unwinding device, a coating main roller, a winding device and some guide rollers, as well as large and small wallboards and other components for installing these roller systems. The servo motor is used for speed regulation, and its tension sensor is used to realize the automatic control of the constant tension of the unwinding and winding during the coating process; the system has functions such as pre-tightening of the base material (anti-unwinding).

The vacuum pumping system uses a molecular pump and a domestic oil diffusion pump as the main exhaust pump to ensure the vacuum required for the coating.

What is ito film: characteristics and uses of ITO film

ITO thin film is an n-type semiconductor material with high electrical conductivity, high visible light transmittance, high mechanical hardness and good chemical stability. Next, let me tell you in detail what the ITO film is, the characteristics and uses of the ITO film.

1. What is ito film
ITO thin film is an n-type semiconductor material with high electrical conductivity, high visible light transmittance, high mechanical hardness and good chemical stability. It is the most commonly used film material for transparent electrodes of liquid crystal displays (LCD), plasma displays (PDP), electroluminescent displays (EL/OLED), touch screens (TouchPanel), solar cells and other electronic instruments.

2. The characteristics and application of ITO thin film

The ITO thin film has a complex cubic ferromanganese structure, and its characteristics mainly include:

1) Good conductivity (resistivity can be as low as 10-4Ω·cm), band gap width 3.5~4.3eV, carrier concentration (1021cm-3) and electron mobility (15~45cm2V-1s-1) are high ;

2) The transmittance in the visible light band can reach more than 85%;

3) The absorption rate of ultraviolet rays is high, which can reach more than 85%;

4) It is reflective to infrared rays, and the reflectivity is higher than 80%;

5) It has attenuation to microwave, and the attenuation rate can reach more than 85%;

6) The film layer has high hardness, wear resistance and chemical corrosion resistance (except hydrofluoric acid, etc.);

7) The film layer has good acid etching and photolithography performance, is convenient for fine processing, and can be etched into different electrical patterns.

With the rapid development of the display device industry, new requirements are put forward for the product performance characteristics of ITO thin films. At the same time, the in-depth development of ITO thin film preparation technology has made it possible to meet the needs of display devices. ITO thin films with different properties can be applied in different display devices.
