The small-scale evaporation coating machine can be used for vacuum evaporating. During the evaporation coating process of the sample, the sample stage can be rotated to obtain a more uniform film. The coating current can reach up to 60A. This type of small evaporation coating machine has a wide application range and can prepare various metal thin films and some non-metal thin films, so it is widely used in the preparation of electrodes and the preparation of organic light-emitting LEDs. The equipment has two sets of evaporation sources, which can be used to prepare double-layer films; each set of evaporation sources are equipped with baffles, which can conveniently control the start and stop of the evaporation process of each evaporation source, and can effectively prevent the film material from being contaminated. The evaporation coater is small in size, which can effectively save laboratory space; it is simple to operate and has strong adaptability to different materials, making it very suitable for laboratory purchases.

The Dual Sources High Vacuum Desktop Evaporation Coater for OLED is an advanced piece of equipment designed for precision and efficiency in the field of thin film deposition. Here are some of its key features:

Stainless Steel Chamber with Excellent Vacuum Performance: The equipment utilizes a stainless steel chamber that provides superior vacuum performance. This is crucial for creating a contamination-free environment, which is essential for high-quality OLED production. The stainless steel construction also ensures durability and resistance to corrosive materials used in the coating process.
Rotatable Sample Stage for Uniform Coating: The sample stage of this evaporator can be rotated. This feature ensures a more uniform coating effect on the OLED substrates. Uniformity is key in OLED manufacturing as it directly affects the performance and longevity of the OLED display. The rotation helps in distributing the evaporated material evenly across the substrate, reducing the risk of uneven film thickness and other coating defects.
High-Temperature Tungsten Wire Basket Heating Source: The equipment uses tungsten wire baskets as its heating source, capable of reaching temperatures up to 1700°C. This high-temperature capability is vital for the efficient evaporation of materials used in OLED production, such as organic and metallic components. The use of tungsten ensures that the heating elements can withstand the high temperatures required for the evaporation process without degrading.
Introduction of Inert and Reactive Gases: The vacuum chamber is designed to allow the introduction of inert gases for cleaning purposes or reactive gases for reactive evaporation coating. This feature enhances the versatility of the equipment, making it suitable for a variety of coating processes. Inert gases like argon or nitrogen can be used to purge the chamber and prevent oxidation, while reactive gases can be introduced to achieve specific coating properties or to deposit compounds.
Precision Gas Flow Control with Needle Valve: The gas inlet of the equipment is equipped with a needle valve, allowing for precise adjustment of the air flow. This level of control is important for maintaining the desired pressure and atmosphere within the vacuum chamber during the coating process. It also enables the operator to fine-tune the process parameters to achieve the best possible coating results.

In summary, the Dual Sources High Vacuum Desktop Evaporation Coater for OLED is a sophisticated piece of equipment that offers excellent vacuum performance, uniform coating capabilities, high-temperature evaporation, versatile gas introduction options, and precise gas flow control. These features make it an ideal choice for research and production in the field of OLED technology, ensuring high-quality and consistent results in the manufacturing of OLED displays.
