  • What are the advantages of jewelry vacuum coating machine in coating?

          The decorations we wear in daily life are coated with a layer of film, such as rings, earrings, necklaces, and decorations applied to other products, all of which are coated with a film by the jewelry pvd coating machine to achieve the effect and performance we want.       Jewelry vibration plating is vacuum-plated by sputtering. Due to the different coating methods, the effect of the thin film prepared by the same plating material will be different. Although it cannot be seen by the naked eye, it does have certain advantages. The film thickness has good stability, because the thickness of the sputter coating layer has a great relationship with the target current and the discharge current. The higher the current, the greater the sputtering efficiency. The thickness of the coating layer is relatively large at the same time. Because as long as the current value is well controlled, how thick or thin the film needs to be.       The film has a strong binding force. During the vacuum plating process, some electrons hit the substrate surface, activate surface atoms, and produce a cleaning effect. The energy obtained by sputtering of the plating material is higher than the energy obtained by evaporation 1 to 2 orders of magnitude, when the atoms of the plated material with such high energy hit the surface of the substrate, more energy can be transferred to the substrate, generating more thermal energy, and accelerating the movement of atoms activated by electrons, and Some of the plating material atoms are fused with each other earlier, and other plating material atoms are deposited in succession to form a film, which strengthens the bonding force between the film layer and the substrate.      The plating material has a wide range, because the sputter coating is sputtered out by high-speed bombardment of argon ions, of course, this thickness is within the allowable range, and the current is controlled well, no matter how many times the coating is repeated, the thickness of the film is No change, the stability of the film thickness can be attributed to the good controllability and repeatability of the film thickness. Unlike metal electroplating, which is restricted by the melting point, only plating materials with a relatively low melting point can be used, and solid materials with sputter coatings can all become plating materials.
  • Introduction to the use steps of pvd vacuum coating machine

             PVD coating machine mainly refers to a type of coating that needs to be performed at a higher vacuum, including many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, and PLD laser sputtering deposition. The main ideas are divided into evaporation and sputtering.  Electric control cabinet operation   1. Turn on the water pump and air source.   2. Turn on the main power.   3. Turn on and maintain the power supply of the pump and the vacuum gauge, the position of the vacuum gauge position V1, wait for its value to be less than 10, and then enter the next step. It takes about 5 minutes.   4. Turn on the mechanical pump and pre-pump, turn on the turbo molecular pump power and start, the vacuum gauge switch is changed to the V2 position, and it takes about 20 minutes to pump to less than 2.   5. Observe that after the turbo molecular pump reading reaches 250, turn off the pump. Turn on the front machine and the high valve to continue the vacuum. After the vacuum reaches a certain level, you can only open the right high vacuum meter to observe the vacuum. The electron gun power can only be turned on after the vacuum reaches 2×10-3.  Machine operation   1. Main power supply.        2. Simultaneously turn on the power of electron gun control Ⅰ and electron gun control Ⅱ: Press the power and delay switch of electron gun control Ⅰ, the delay, power and protection lights are on, and the delay and protection lights are off after three minutes, if the back door is not closed or the water flow relay has Failure, the protection lamp will be on.   3. Turn on the high voltage, the high voltage will reach more than 10KV, the beam current can be adjusted to about 200mA, the curtain grid is 20V/100mA, the filament current is 1.2A, and the deflection current swings between 1~1.7.   Shutdown sequence   1. Turn off the high vacuum gauge head and turn off the molecular pump.   2. When the molecular pump shows 50, turn off the high valve, the fore stage, and the mechanical pump in sequence. This period takes about 40 minutes.   3. When it is below 50, turn off the maintenance pump
  • Advantage of glove box combination in the coating process

    In the vacuum environment, the technology of heating the material and plating it on the substrate is vacuum evaporation plating. In particular, vacuum evaporation is the process of evaporation or sublimation of the material to be coated in vacuum to make it precipitate on the surface of the workpiece or substrate. The coating in vacuum evaporation is usually aluminum film, but other coatings can also be formed by evaporation deposition. However, the existing coating machine structure is more complex and high cost, which can not fully meet the needs of industrial production, and is not conducive to reducing the cost of coating products.A glove box evaporation and plating integrated machine is provided as sample of our high quality pvd coating machines. The system is composed of a vacuum coating system and a glove box system, which can complete the film evaporation and plating in a high vacuum evaporation and plating chamber, and store, prepare and test samples after evaporation and plating in a high-purity inert gas atmosphere of the glove box.The combination of pvd coating machine and glove box can realize the completely closed production of evaporation coating, packaging, testing and other processes, so that the whole film growth and device preparation process are highly integrated in a complete system of controllable environmental atmosphere, eliminating the influence of unstable factors in the atmospheric environment during the preparation of organic large-area circuit, and ensuring the preparation of high-performance and large-area organic photoelectric devices and circuits.The beneficial effects are: high production efficiency and low cost of coating products.
