Effect of Surface Roughness on Thermal Performance of Integrated Heat Spreaders of microelectronics package assembly

• Steady State Thermal Analysis of a microelectronics system to analyze the effect of surface roughness on the performance of Integrated Heat Spreaders (IHS) in terms of temperature of the die and consequently the contact surface resistance

• Modeled a local model with various roughness profiles to simulate the contact resistance between TIM1- IHS and TIM 2- Heat Sink using SolidWorks Simulation

• Analyzed global model with all the components including die, TIM 1, Integrated Heat Spreader (IHS), TIM 2 and heat sink to analyze the die temperature in ANSYS Workbench

• Plotted the relation between surface roughness (SR) and thermal contact resistance (TR) as TR decreases with increase in SR until a critical value after which the increase is SR results in increased TR Design and Manufacturing of smart Refrigerator Shelf (IoT)

• Carried out the end to end product development from idea conception to manufacturing for Smart Refrigerator Shelf

• Developed an algorithm and code on MATLAB which can predict the item that has been taken out from the refrigerator

• Programmed the Arduino for force resistive sensors and designed the mechanism to install the sensors in the shelf

• Integrated the MATLAB Code and Arduino code through ThingSpeak to get the output via interaction between the two Finite Element Analysis of composite bar of different conductivities with varying cross-section

• Performed Finite Element Analysis of composite bar of different conductivities using linear, quadratic and cubic elements

• Developed the MATLAB code for Temperature fields, Heat flux fields, L2 Norm Error and Energy Norm Error for all the elements and compared the results with Analytical as well as ABAQUS Solutions
