Abstract:
1. A device comprising: a housing including a bottom portion and a rim portion integrally formed around a perimeter of the bottom portion, the bottom portion including one or more holes to allow drainage of sacrificial material during a print forming process employed during manufacture of the device; a substrate strip constituting part of a cantilever beam formed from the rim portion and protruding over an area of the bottom portion; first conductive layer laid on top of the substrate strip; an inert layer laid on top of the first conductive layer; a second conductive layer laid on top of the inert layer; a first via formed within the rim portion and coupled to the first conductive layer; a second via formed within the rim portion and coupled to the second conductive layer; a proof mass attached to the cantilever beam; a void area separating the cantilever beam from the bottom portion, the void area configured to allow at least one end of the cantilever beam to move vertically relative to the bottom portion in response to movement of the device, the void area formed by drainage of the sacrificial material through the holes during the print forming process; a lid placed on a top area of the rim portion to seal the cantilever beam within the void area; a first surface mount pad on a surface of the lid and coupled to the first via; and a second surface mount pad on the surface of the lid and coupled to the second via.
