Machine working principles
ZZS series vacuum coating machine adopts electronic gun bombardment coating material evaporation technology to achieve the purpose of changing the surface performance of the workpiece and get desired coating products.
vacuum evaporation coating means putting the material in the chamber to heat it until evaporate at the vacuum of 1.3x10-2Pa～1.3×10-3Pa . When evaporation molecules' average free path is greater than the linear size of the vacuum coating chamber, the atoms and molecules of steam escape from the surface of the evaporation source, attacked and blocked little by other molecules or atoms, so it can directly arrive to the surface of the substrate , due to the relatively low temperature of the substrate, it condense to film.
E-beam gun working principles:
E-beam gun produces electron beam by high voltage in the vacuum condition ,the electron beam is accelerated after passing the electric field of 5 ~ 10KV, by the action of a specific magnetic field ,through certain route, focus on the surface of the material to be vaporized to bombard the material, then transfer the energy to the material to be vaporized and melt it until vaporized
The material to be evaporated is placed in a water-cooled crucible in electron beam evaporation apparatus . only a small part of the material is bombarded by the electron gun and the most of remaining material is in a low temperature state in the cooling crucible, keeping solid state, there is no chance that material reacts with the crucible. Its can avoid pollution by other substances in the deposition process and get the desired pure clean film.
Electron beam evaporation apparatus is suitable for coating high purity, hard material film. For the evaporating of the refractory material, several or more crucibles can be placed simultaneously and evaporate several material at same time or independently. thereby coating the optical film, electronics and optoelectronics field material.
Resistance evaporation source:
Usually three water-cooled electrodes can be installed in two evaporation boats. A set of power supply for public using which connect separately by one shift switch, alternately evaporate (can be controlled independently).it can adopt the structure of 4 water-cooled electrodes erection joint.
Electron beam evaporation source:
Single gun is equipped with one set of power supply, one operational hand-held remote control box. Two guns are equipped one set of power supply, two operational hand-held remote control boxes.
Workpiece driving device:
It consists of gear motor outside of the door, synchronous belt, magnetic fluid, the gear at the top of vacuum chamber ,workpiece holder and other components .The transmission of gear motor drive the synchronous pulley outside of the magnetic fluid through reducer, then achieve the revolution of workpiece through the gear engagement inside of magnetic fluid . Gear motor can stepless speed regulation. The device can be installed flat workpiece plate, spherical workpiece plate, planetary workpiece plate, fan workpiece plate, other forms of workpiece plate and the interchange is very convenient.
Workpiece baking device:
There are upper baking and lower baking and upper baking use tubular heater, the highest baking temperature up to 350 ℃, tubular heaters arranged evenly and multiple temperature control, each heating wire has a K- type thermocouple to test temperature. Heating wire connector is water cooling structure ,if the baking cannot open, the whole heating zone can be controlled and adjustable. Lower baking is iodine-tungsten lamp heating, its heating fast.
Baffle structure:
It close to evaporation source which is used to shield the impurities and dirty evaporation material when pre-melting and to shield the evaporation material when get the required film thickness to ensure the purity and thickness. The specific height and the distance to the evaporation source can be adjusted. Baffle is pneumatic rotation structure. Sometimes one baffle can be used by resistance steaming and electron gun evaporation source at same time.
Vacuum measurement socket:
It is placed behind the chamber and can be installed in different vacuum measuring tube which is national standard opening size, easy to install required vacuum regulation.
Chamber deflation valve
It is placed behind the chamber for deflating the gas. There is silencer at the deflation gas port(silencer is leaded in the clean-room) to prevent the dust is sucked in the chamber and there are two different diameter deflation valve(One group can be adjustable)to realize the requirements of fast or slow.
Chamber lighting
Low power bromine tungsten lamp for evaporation room lighting which installation position can be moved.
Hold-down mechanism
Be installed on the door of the chamber . when close the door ,the cylinder running. Drive the rotating wheel to compress the door.
