InvenSense’s dual-axis gyroscopes utilize MEMS technology which consists of microscopic moving silicon
structures to sense rotations and have a shock tolerance of 10,000g. InvenSense packages its gyroscopes
as it deems proper for protection against normal handling and shipping. It recommends the following
handling precautions to prevent potential damage.
1. Individual or trays of gyroscopes should not be dropped on hard surfaces. Components in trays if dropped
could be subjected to g-forces in excess of 10,000g.
2. Printed circuit boards with mounted gyroscopes should not be separated by manually snapping apart. This
could create g-forces in excess of 10,000g.
9.11 Gyroscope Surface Mount Guidelines
Any material used in the surface mount assembly process of the MEMS gyroscope should be free of
restricted RoHS elements or compounds. Pb-free solders should be used for assembly.
In order to assure gyroscope performance, several industry standard guidelines need to be considered for
surface mounting. These guidelines are for both printed circuit board (PCB) design and surface mount
assembly and are available from packaging and assembly houses.
When using MEMS gyroscope components in plastic packages, package stress due to PCB mounting and
assembly could affect the output offset and its value over a wide range of temperatures. This is caused by
the mismatch between the Coefficient Temperature Expansion (CTE) of the package material and the PCB.
Care must be taken to avoid package stress due to mounting.
