Role of Shock Response Spectrum in Electronic Product Suspension Design

摘要

The Shock Response Spectrum (SRS) analysis provides general guidelines for the design of suspensions and cushions for shock- protection of fragile components. This paper presents the central results of the SRS approach in the context of designing a compliant suspension for a Printed Circuit Board (PCB) in a wireless telephone handset, for shock amelioration. The dynamic response of the PCB, to a spectrum of shock pulses, is measured for a rigid suspension and for three versions of a grommeted compliant suspension.
