Abstract

As mechanical shock performance expectations increase in personal communication devices, improved methods of shock isolation are needed to satisfy these demands. Existing designs utilize boots or snubbers formed from butyl or silicone to enclose shock sensitive components (i.e.: quartz, ceramic components). This approach can cause the device to be compressed between PCBs, other components, and the boot itself possibly inducing mechanical damage. This new approach uti- lizes the same materials as before, however, air pockets with tiny air valves allow for additional shock protection.
