Drop tests and impact simulation for cell phones Journal
Figure 2: Simulation of a cell phone assembly drop test using SolidWorks sofware. Figure 3: You can easily define the orientation of the model as well as the height it is being dropped from.... Reliability of handheld electronic devices such as cell phones and PDAs due to drop/impact event is a major concern in electronics industry. During a drop/impact event, the PCB assembly inside the phone casing vibrates causing a flexural/bending motion of the board. The PCB bending results in high stress or strain on solder joints of electronic components due to high level of impact forces. It

Modeling Techniques for Board Level Drop Test for a Wafer

A drop test is a method of testing the in-flight characteristics of prototype or experimental aircraft and spacecraft by raising the test vehicle to a specific altitude and then releasing it....
Transient Dynamic Simulation and Full-Field Test Validation for A Slim-PCB Of Mobile Phone under Drop / Impact Abstract: Product durability due to drop shock is a critical element for assessment of reliability for handheld devices.

How we test cell phones Digital Trends
drop tests familiar, the technology behind them is more complex than it looks. To simulate an object dropping and hitting a hard surface, the simulation soft- ware has to solve the following equation iteratively, because as the object falls john stevens search and reflect pdf As depicted in Figure 3, a drop test machine is employed for the drop/impact experiments on cell phones. In the experiment, a specimen is released to fall freely from the bracket of the drop test machine down to the floor.. Marine transgression and regression pdf

drop test performance of a mobile electronic device. • These results show that ANSYS LS-DYNA submodeling techniques can be employed to rapidly and accurately

  • The drop tests were conducted using a Lansmont M23 TTSII shock test system, which applies a single half-sine shock impact pulse to the test vehicle for each drop.
  • Hi, can anyone tell me the procedure how to conduct drop-test analysis in ANSYS LS-Dyna step-by-step..??? I tried to use help tutorial but its not so useful for me. I want to do drop-test for an electronic component of size 80x50x20mm.
  • Drop/impact protection is an important concern for the design of portable electronic products. Drop/impact forces may cause severe functional damage in form of component failure and/or interconnection breakage.
  • Drop Testing. At NTS, we can evaluate vehicles, products and packaging using multiple varieties of drop testing. As a crucial aspect of testing for many items and materials, drop testing serves as an important indicator of quality and durability.
