This type of small plasma sputtering coating machine adopts two-stage sputtering method, which is widely used for SEM sample preparation or metal coating experiment. Using low-temperature plasma sputtering process, there is no high temperature during the coating process, and it is not easy to produce thermal damage. This small plasma sputtering coater uses PLC control system, all touch screen operation, easy to learn and use. This equipment is equipped with a rotatable heating sample stage, which can improve the uniformity of the coating and the adhesion of the film. This small plasma sputtering instrument uses a PLC control system, all touch screen operation, easy to learn and use. The equipment is small in size and beautiful in appearance, making it the best choice for laboratory coating experiments.
