Vacuum coating technology
Common coating techniques are shown in the figure, ranging from traditional electroplating to today's vapor phase methods, such as physical vapor deposition(PVD) and chemical vapor deposition(CVD). As the industry progresses, the requirements for the quality of the film are also raised. Compared with the traditional electroplating method, the vacuum environment can ensure that no other substances are added to the film during the process. In today's high-tech industry and the high-quality requirements of the semiconductor industry, vacuum coating technology is the most suitable coating technology, and it is also a key technology for high-tech industries.
