pvd Vacuum sputtering coating machine of magnetic recording media

The pvd sputtering coating equipment of magnetic recording media requires sputtering targets with low gas content, high purity, fine-grained microstructure, high magnetic penetration and utilization, uniform metallography, and excellent electrical and mechanical properties.

PVD sputtering coating machine

The film stretches during aluminum plating

the reason:

① The substrate tension is too high. Solution: Adjust the unwinding tension control system to appropriately reduce the tension.

② The cooling system is operating abnormally. Solution: Check the cooling system and clear the fault.

3. There are brown stripes on the surface of the film

the reason:

① Solutions for low vacuum: clean the aluminum delivery equipment, evaporation equipment, cooling system, unwinding equipment, and guide rollers in the vacuum chamber; check the vacuum system; reduce the environmental humidity.

② The film releases gas. Solution: Film pre-monotonous; extend the vacuum time.

③ Too much aluminum is sprayed. Solution: forward speed; reduce the water flow of the evaporation boat; reduce the aluminum delivery speed.

④ There are impurities in the evaporation vessel. Solution: Clean the evaporation boat and heat insulation board.

⑤ The evaporator is aging. Solution: Replace the evaporation boat.
