Electromagnetic insulation (EMI) is an important
but expensive process necessary for a number of modern applications,
including shielding in mobile phones. Meanwhile, outdated coating
machines, including sputtering magnetrons, sit idle.
This project was focused on developing an economical
process for applying insulating oxide coatings for different applications.
A large disused air-to-air magnetron was refurbished and adapted
to use in large-scale high-quality coating, including lightweight
EMI shielding coating for mobile phones. The coating process takes
place under vacuum, meaning virtually no pollutants in the workplace.
Additional achievements included the development of improved targets
and new gas supply and process control systems. Sputtering rate
was also improved and prototypes of pulsed DC power supplies have
been produced and are operating.
Partners first intend to apply their new
coating system to the EMI shielding coating of mobile phone components
for NOKIA. Additional potential applications are envisioned in a
variety of other sectors. Subsidiaries are now being established
in a number of foreign countries.
