The system incorporates proven design features based on decades of experience that produce exceptional results with easy to use software and dependable run to run consistency. We strive to continuously obtain customer feedback from coating engineers, operators, and maintenance personnel to improve design features that will minimize system downtime and increase overall productivity. Subsystem equipment of our systems are from reliable and brand manufacturers such as Baosi, Edwards, Inficon, Burkert, Omron to name a few. This allows our clients to benefit from the depths of Guotai and its vendors for the availability of service and spare parts.

• Coating Process Capability and Support

The system includes optional process development, system calibration, film characterization and uniformity adjustment to less than 0.5%. They can be delivered with multiple, fully developed, production-ready coating processes, pre-programmed to minimize system downtime between production changeover's and to maximize run efficiencies and product yields. Calibration of the process is so consistent that new designs may be supplier to the operator from a remote site with the results from a test run analyzed and a small adjustment in calibration made before final production. Designed for run-to-run repeatability and to deliver excellent results after a minimum number of test coatings, the system lends itself to a fully automatic operation reducing time, manpower, and costs-even with high layer counts and complex layer stacks.

The processing methods of vacuum coating equipment of different processes are different. Inadvertent small faults may affect the normal operation of the entire machine and equipment. When problems are encountered, they need to be investigated one by one. Having experienced masters can often solve many problems. Speaking of the uniformity of the coating, this is one of the criteria for evaluating the quality of a vacuum coating machine. In the process of machine coating, processing the uneven coating of vacuum coating equipment, it is necessary to investigate the problems that may affect the uniformity of the coating, and the inspection and repair are completed before mass production. The coating of all coating equipment will be affected by some conditions that affect the uniformity of the coating. Take the magnetron sputtering vacuum coating equipment as a brief example:

The work of magnetron sputtering coating is originally not complicated. By equipping an efficient and stable sputtering source to bombard the target under a certain vacuum environment in the coating chamber, the target is decomposed. This is a PVD physical process. The decomposed target Atoms are deposited through the process to form a film on the surface of the product. In the reaction process, the influence of the uniformity of the magnetic field, the pressure holding of the vacuum environment, and the protective gas on the uniformity of the film should be considered. However, some uneven changes in the film layer may also be caused by the instability of the sputtering source or the target material. This type of situation is more difficult to deal with.

It should be understood that regardless of the accuracy of the monitor that comes with the coating equipment, it can only control the thickness of the film at a single point in the coating room. Generally, it refers to the middle position of the product. By controlling the uniformity of the film at this base point to ensure that the product is far away from this base point. Uniformity of the film.

The vacuum environment is controlled by pumping. To maintain a stable vacuum at all times requires an accurate detection and control system. When the vacuum reaches the required state, the pumping needs to be stopped, and the vacuum will be lower than the required state to be pumped in time. Voltage stabilization. The coating vacuum degree has a reasonable interval range. The smaller the difference in this range, the greater the accuracy required, the more difficult the control, and the better and more stable relative voltage stabilization; the greater the interval range, the lower the accuracy, and the requirements for the detection and control system are also Lower, the relative pressure fluctuation is greater, and the greater the impact on the uniformity of the film.

In the past few years, more and more customers have higher and higher requirements for vacuum coating equipment, especially in terms of film density and uniformity quality. For manufacturers of coating machines, they have improved their own process technology. It is the guarantee of competitiveness.
