We have recently started serial deliveries of very small and precise gold-plated parts used as diaphragm in microphones. Each part is tiny, measuring around 4×6 mm and are etched from 100 micron thick steel plate. The parts are manufactured to extremely tight tolerances (+/- 20 microns) which are less then the industry standard minimum tolerance of +/- 25 microns. All this required in order to provide a final product with optimal sound characteristics.
