Abstract :
This paper reviews the design and manufacture of an improved quad relief mount (QRM) resonator. It discusses the mechanical resonance and how the lead-frame structure was modified to push the mechanical resonance well above 2 kHz. The results of a design of experiments (DOE) are discussed and show that the azimuthal mounting angle (Ψ) has a dramatic effect on the g-sensitivity performance of the QRM resonator. Finally, preliminary results on a QRM design that uses a larger diameter blank (0.390") are compared to the current 0.320" QRM design.
