An Enhanced Micro-Suspension System

VueReal is currently developing LED technology that requires transfer of devices during fabrication to other sites. However, these devices are fragile. During the transfer process, an unacceptably large number of devices are damaged due to failures in their suspension systems. This reduces the fabrication yield and therefore increases production cost. It is not obvious whether these failures arise due to temperature variations, shocks during transportation, or other reasons. This project aims to address this challenge and propose directions for further development.

The objective of this project is to propose a solution that will alleviate device failures during transportation. The first step in the proposed approach is to model and simulate the device and its suspension system using Finite Element Modeling and to carry out thermal and structural (shock) analyses on the model. This will allow us to identify the root cause(s) of those failures. We will then re-design the suspension system in order to address those causes. Different solutions will be developed, simulated, and validated. Finally, a candidate solution will be proposed.
