The vacuum chamber module is designed for laser welding small production series of packages under vacuum or shielded atmosphere.
As an effective alternative to a full-sized glovebox, the vacuum chamber module fits inside the NOVA-6. The module consists of a vacuum chamber, vacuum pump, safety overpressure valve, baseplate and piping.
The vacuum pump evacuates the chamber to a vacuum of a few mBar. In this vacuum, the laser can weld through the cover glass.
Optionally the operator can choose to flush the chamber (and the package) with a controlled atmosphere. After 2 to 3 repeat pumping and flushing actions, the device will have an atmosphere suitable for closing the package.
- Low moisture and oxygen content
- Vacuum pump evacuates the chamber to a vacuum
- Laser welding through the cover glass
- Ideal for specialty and low-volume series
