Gold coating on hearing devices

Demaco sold several gold coating machines to one of the global leaders of advanced miniature components for hearing instruments.

The product range includes balanced armature receivers, high-end microphones and electromechanical components for the hearing instruments and high-end audio headsets. One of the major components in these hearing devices needs to have a thin gold coating layer. Our gold coating systems need to have a maximum reliability as they are in operation 24/7. Pumpdown time from Atmospheric pressure to 5.10 e-6 mBar takes only 30 minutes. At this pressure the gold coating will start.
