Abstract:
1. A method of manufacturing a pendulous acceleration sensor, which comprises a pendulous electrode in a thickness of a substrate, the method comprising: (a) forming an encapsulation cover provided with at least one counter electrode thereunder; (b) forming spacers of a preset thickness on a first surface being one of the cover and the substrate; (c) plating a eutectic coating on a second surface being another of said one of the cover and the substrate, a first thickness of said coating measured from said second surface being greater than the preset thickness of said spacers from said first surface; (d) positioning the cover on the substrate; and (e) heating the eutectic coating causing a subsidence of the cover until said spacer contact said second surface, wherein after said subsidence, said coating is a second thickness equal to the preset thickness.
