SHOCK RESISTANCE

One of the areas in which micromechanical resonator oscillators perform better over quartz crystal is the shock resistance. MEMS resonator typically has mass as small as 10-14kg and its stiffness is usually as high as tens thousand of N for high frequency structures. Simulations show being able to achieve up to 100,000g shock. The resonator itself will survive the g-shock very well.

However, the impact of the g-shock for the packaging could be severe since the packaging contains most of the mass. In this particular evaluation, we flip-chip resonator on top of an oscillator ASIC with solder balls as show below in Figure 1, which probably represent a worse case package compared to ceramic package or plastic over-mold package.

If the oscillator experience 30,000g shock along x, y, and z-axis, the z-axis stress and two shear stresses are listed in Table 1. Therefore, this type of oscillator will survive 30,000g of shock. A recent test has shown that MEMS oscillators can survived the g-shock of an air gun. All of the tested 125MHz MEMS oscillator tested, did not show any performance degradation.

VIBRATION OPERATION

Silicon MEMS oscillators were tested under random vibration ranging from 2.84G to 50G. The output spectral out of the oven for a thermal cycle test, as shown below, the frequency deviation across the temperature did not change with time.

Based on results of a previous test, we know that the packaged resonator passed the Height Temperature Storage Life (HTSL), this data indicates that the resonator/oscillator package did not degrade with high temperature storage.

With all the reliability data shown in previous sections, and with the fact these oscillators have met the XO specification including jitter, power consumption, voltage variation, and temperature stability, MEMS-based silicon resonator oscillators are now ready for commercialized shipping in timing and frequency reference applications.
