|Portable electronic devices suffer from impact-induced failure in usage. These products must pass drop or impact tests before shipment, so that there are no grievances at the customer end due to poor life of the product. Hence, drop or impact performance is one of the important concerns in product design. Because of the small size of these kind of electronics products, it is very expensive, time-consuming, and difficult to conduct drop tests to detect the failure mechanism and identify their drop behaviors. A large number of sensors are required in the extremely small space of the electronic device, so as to obtain sufficient data for failure analysis. To overcome this hurdle, a combination of only a few sensors, a rudimentary test rig, and finite element analysis with the help of software can be used to study device behavior during impact. Recent work has shown that due to the multiple impacts that result during an accidental drop of a portable electronic product, the propensity for damage to the product can be significantly higher than in a single impact. When viewed in light of these findings, conventional methods for drop-testing of portable products, either constrained or free, suffer from drawbacks. In the former, the object being tested is not allowed to move naturally during impact, and in the latter, it is difficult to control the orientation of the object at impact and to instrument it. In this project, a new method of drop-testing has been designed, that combines the advantages of the constrained and free methods, without their drawbacks. It is proposed that the object being tested be suspended onto a guided drop-table in the precise desired impact orientation. The test device, drop test and correlation of analysis to test data are illustrated in the report.|
