We designed the Air Retractable Magnet Bar (ARM-Bar™) for sputtering ferromagnetic materials: alloys of iron, cobalt and a few “rare-earth" elements.
With the magnet bar raised and lowered using air bladders, the ARM-Bar™ provides the utilization and up-time benefits of a rotary cathode while allowing safe and easy insertion into the target, adjustment and removal.
In order to penetrate the magnetic material, the ARM-Bar™ has our strongest magnet bar, the QRM-Bar™.
Typical applications include EMI shielding, nickel sputtering as an adhesion layer for polyimide substrates, and magnetic storage.
