Problems solved by technology

[0003] The above-mentioned vacuum magnetron sputtering coating machine sputters the required metal layer on one side of the roll substrate, and has the following disadvantages: (1), the vacuum chamber of the coating machine usually adopts a square chamber, and the vacuum obtaining system adopts an oil diffusion pump The system is distributed on both sides of the vacuum chamber. This layout causes uneven vacuum in the vacuum chamber, resulting in uneven sputtering film thickness; the oil diffusion pump often returns oil, which will cause the workpiece substrate in the vacuum chamber An oil film is formed on the surface, resulting in poor bonding between the sputtering film and the substrate; in addition, the power consumption of the oil diffusion pump is relatively large, because its control method is switch value control, so even if the pumping speed of the process becomes small, it can only use full power. output, the energy consumption is very large
(2) Usually only one set of rewinding and unwinding system is configured, so only one roll can be sputtered, and the work efficiency is low
(3) Usually, it is only equipped with sputtering targets, and not equipped with ion source treatment. When plating certain substrates, the peeling strength between the film layer and the substrate will be insufficient.
