Description

Vacuum furnace

The present invention relates to a vacuum furnace body.

The world is now using round furnace design. Always cause PVD (Physical Vapor Deposition) coating (coating), there are many blind spots.

During production, the product often appears to be falsely attached, and the film is leaking. Pseudo-adhesion is a technical problem that cannot be seen and is the most headache of PVD coating (coating). Severe false attachment can be detected immediately after the furnace is leaked. The most feared is the slight falseness. It is often the product that comes to the market that the PVD coating (coating) leaks white and affects goodwill.

Referring to Figures 1-3, the vacuum furnace body 1' of a circular furnace body design in the world includes a vacuum chamber 11', an evaporation target 12', an evaporation target 13', an object hanger 14', a self-rotating frame 15' and a public Turntable 16'.

The evaporation target 12' is distributed on the outer surface of the vacuum chamber 11'. The prior art structure causes the entire vacuum chamber 11' to be covered with various deposited titanium dust, residue and oxidizing species R. The mixed gas is released during the heating process, and it is easy to contaminate the surface of the object to be coated, thereby causing false adhesion, causing the color to be irregular, and the residue is likely to fall on the object to be plated to cause whitening, and the temperature during the coating process is always rising. It is necessary to stop the machine and wait for the temperature to cool down to the required temperature before the coating can be followed. Referring to Figure 2, the evaporation target 13' is distributed within the vacuum chamber 11'. It can be seen that the target source and the target source cannot mutually Cross evaporation. It is easy to cause the dead zone 17', and it is easy to cause the object to be plated to have the same film thickness at the concave corner position as the positive angle position, so that the film thickness of the PVD coating (coating) is not uniform. The larger the furnace body, the more uneven the PVD coating (coating) film thickness. The concave corner position is larger and more serious than the PVD coating (coating) film thickness at the positive angular position. The plated product on the object hanger 14' cannot be rotated. After PVD coating (coating), the film thickness of the product cannot be uniform, such as 4un film thickness. The error value is about 0.5un-1un.
