Abstract
A 3-axis sensor package with on-board sensor support chip on a single chip. In one aspect of the invention, a sensor package includes an X-axis sensor circuit component, a Y-axis sensor circuit component, or alternatively a combined X/Y-axis sensor circuit component, and a Z-axis sensor circuit component, each mounted to a top surface of a rigid substrate, or alternatively to a printed circuit board (PCB). The pads may be arranged in variety of designs, including a leadless chip carrier (LCC) design and a ball grid array (BGA) design. An application-specific integrated circuit (ASIC), or sensor support chip, is additionally mounted to the top surface of the rigid substrate. The sensor components and ASIC may be ball bonded or wire bonded to the substrate.
