Effect of material creeping on the reliability of thermal interface of LED spotlight module
In this study,the reliability of LED spotlight module with consideration of the contact between a module made of polybutylene terephthalate (PBT) and the aluminum heat sink is investigated by non-linear finite element modeling.The mechanical behavior of the contact interface under high temperature storage was simulated.The force applied on the thermal interface (FTIM) was obtained from the simulation and experiments.The simulation results agree with the experimental measurement.The proposed simulation is an efficient tool to depict the effect of the creeping of PBT on the reliability of thermal interface of LED spotlight module.
